Application Example OmniSwitch 9000 Series

Application Example

The following application example shows one of the many ways OmniSwitch 9000 switches can be used in an Enterprise network setting:

• Core Switch. In this example, an OS9800 is used as the core switch. Because the example network has

a high-speed Gigabit Ethernet or 10-gigabit Ethernet backbone, the Network Interface (NI) cards in the chassis will be comprised mainly of Gigabit Ethernet or 10-gigabit Ethernet Network Interface (GNI, XNI) modules. The core switch connects to wiring closet switches as well as the company server farm.

• Wiring Closet Switches. The switches in wiring closets 1, 2, and 3 must contain some GNI/XNI

modules in order to link to the Gigabit Ethernet/10-gigabit Ethernet core switch. However, in most cases, these switches will largely be comprised of Gigabit Ethernet Network Interface (GNI) modules. GNI modules support either 10/100/1000 (copper) or 100/1000 (fiber) Gigabit Ethernet connections. These Ethernet ports connect to various network devices, such as workstations, IP phones, and servers.

OmniSwitch 9000 Series Availability Features

Availability Features

The switch provides a broad variety of Availability features. Availability features are hardware and software-based safeguards that help prevent the loss of data flow in the unlikely event of a subsystem failure. In addition, some Availability features allow you to maintain or replace hardware components without powering off your switch or interrupting switch operations. Combined, these features provide added resiliency and help ensure that your switch is consistently available for your day-to-day network operations.

Hardware-related Availability features include:

• Hardware Redundancy

• Smart Continuous Switching

• Software Rollback

• Hot Swapping

• Hardware Monitoring

• Power Checking Sequence

Information on software-related availability is provided in the OmniSwitch 6800/9000 Switch Management Guide and the OmniSwitch 6800/9000 Network Configuration Guide. Refer to the corresponding

feature chapter (e.g., VRRP).

Hardware Redundancy

Hardware redundancy refers to backup hardware components. If primary hardware components fail or go offline for any reason, the redundant hardware automatically assumes the primary hardware functions (this is also referred to as failover). The following components offer redundancy:

• Chassis Management Modules (CMMs)

• Power Supplies

• Fan Units

• MAC EEPROM

Note. Redundancy is a key Availability feature; it is recommended that you install redundant hardware components in your switch whenever possible. However, CMM redundancy is not supported on the OS9600 switch because it contains only one CMM slot.

For detailed information on CMM redundancy, refer to Chapter 4, “Chassis Management Module

(CMM).” For information on power supply and fan redundancy, refer to Chapter 2, “Chassis and Power Supplies.”

OmniSwitch 9000 Series Hardware Users Guide June 2007 page 1-3

Availability Features OmniSwitch 9000 Series

Smart Continuous Switching

In redundant CMM configurations, the switch provides support for NIs during failover. In other words, if the primary CMM fails or goes offline for any reason, NI modules will continue data transmission and routing functions during the secondary CMM’s takeover process. This Availability feature is referred to as Smart Continuous Switching.

Incoming Layer 2 packets will continue to be sent to the appropriate egress port during failover. Known routes will also be supported. (Note, however, that the NI cannot learn new routes without CMM support. Any new route information will be ignored.) Spanning Tree will continue handling BPDUs received on the switch ports, as well as port link up and down states. The Spanning Tree topology will not be disrupted.

Note. Smart Continuous Switching is designed to maintain data flow only during CMM failover and is not intended to support long-term data flow. If both the primary and secondary CMM modules go offline or are removed from the chassis, switch operations (including all NI support) will be disabled. However, smart continuous switching is not possible on the OS9600 switch because it contains only one CMM slot.

For more information on CMM redundancy and the failover process, refer to Chapter 4, “Chassis Manage-

ment Module (CMM).”

Software Rollback

Software rollback (also referred to as image rollback) essentially allows the switch to return to a prior “last known good” version of software in the event of a system software problem. The CMM controls software rollback through its resilient directory structure design (i.e., /flash/working and /flash/certified).

For detailed information on the software rollback feature, as well as the switch’s /flash/working and

/flash/certified directories, refer to the “Managing CMM Directory Contents” chapter in the Switch Management Guide.

page 1-4 OmniSwitch 9000 Series Hardware Users Guide June 2007

OmniSwitch 9000 Series Availability Features

Hot Swapping

Hot swapping refers to the action of adding, removing, or replacing certain hardware components without powering off your switch and disrupting other components in the chassis. This feature greatly facilitates hardware upgrades and maintenance and also allows you to easily replace components in the unlikely event of hardware failure. The following hardware components can be hot swapped:

• Chassis Management Modules (CMMs)

• Gigabit Ethernet Network Interface modules (GNIs)

• 10-gigabit Ethernet Network Interface modules (XNIs)

• Power supplies

• Fan tray

Hot Swapping Non-Redundant Management Modules and Power Supplies. If there is only one CMM or power supply installed in the chassis and either of these components is removed or replaced, all switch functions will stop until a replacement is installed. However, hot swapping is not possible on the OS9600 switch because it contains only one CMM slot.

Hot Swapping NI Modules. It is recommended that you hot swap NIs of the same type (e.g., OS9-GNI-C24) whenever possible. Otherwise, the network configuration may be adversely affected.

For information on hot swapping CMMs, refer to Chapter 4, “Chassis Management Module (CMM).” For information on hot swapping NI modules, refer to Chapter 5, “Network Interface (NI) Modules.” For information on hot swapping power supplies and the fan tray, refer to Chapter 2, “Chassis and Power

Supplies.”

Hardware Monitoring

Automatic Monitoring

Automatic monitoring refers to the switch’s built-in sensors that automatically monitor operations. The majority of automatic monitoring is provided by the CMM. If an error is detected (e.g., over-threshold temperature), the CMM immediately sends a trap to the user. The trap is displayed on the console in the form of a text error message. (In the case of an over-threshold temperature condition, the CMM displays an amber TEMP LED in addition to sending a trap.)

LEDs

LEDs, which provide visual status information, are provided on the CMM, NI, and power supply front panels. LEDs are used to indicate conditions, such as hardware and software status, temperature errors, link integrity, data flow, etc. For detailed LED descriptions, refer to the corresponding hardware component chapter (e.g., “Network Interface (NI) Modules”).

User-Driven Monitoring

User-driven hardware monitoring refers to CLI commands that are entered by the user in order to access the current status of hardware components. The user enters “show” commands that output information to the console. The Show commands for all the features are described in detail in the OmniSwitch CLI Refer- ence Guide.

OmniSwitch 9000 Series Hardware Users Guide June 2007 page 1-5

Availability Features OmniSwitch 9000 Series

Power Checking Sequence

The power checking sequence is another built-in Availability feature. This feature helps regulate power in the switch whenever the switch is booted or an NI module is installed in the chassis.

The sequence is a joint effort between the CMM, the NI modules, and the power supplies. During the boot sequence, the primary CMM automatically compares the power consumption required by installed NIs with the power available from the power supplies. If there is not adequate power to support all NIs, the CMM will power on only the supported number of NIs, starting from the first NI slot position.

Important. During the power checking sequence, CMMs receive priority and are always powered on. NI modules are then powered on sequentially by slot position. In other words, the NI in slot 1 is powered on, then slot 2, then slot 3, etc. For information on slot positions, refer to Chapter 2, “Chassis and Power

Supplies.”

Installing a New NI into a Running Chassis

When an NI module is installed in the chassis, only a small portion of the circuitry is initially powered up. The CMM immediately reads the incoming module’s ID and determines how much power the module will require. If the number of power supplies installed in the chassis can provide sufficient power, the CMM turns on the incoming module. If the number of installed power supplies cannot provide sufficient power, the incoming NI will remain powered off.

Rack-Mounting

Refer to the important guidelines below before installing the OmniSwitch 9800/9700/9600 chassis in a rack.

• Be sure that all modules and power supplies are removed before rack-mounting the switch. For instruc-

tions on removing CMM or NI modules, refer to Chapter 5, “Network Interface (NI) Modules.” For instructions on removing power supplies, refer to “Removing a Power Supply” on page 2-30.

• Rack-mounting the chassis requires three people—two people to hold the chassis and position it in the

rack and a third person to secure the chassis to the rack using the attachment screws.

• The chassis has two integral rack-mount flanges that support standard 19-inch rack mount installa-

tions. Refer to page 2-15 for information on optional rack-mounting hardware.

• Alcatel-Lucent does not provide rack-mount screws. Use the screws supplied by the rack vendor.

• To prevent a rack from becoming top heavy, it is recommended that you install the switch at the

bottom of the rack whenever possible.

• If you are installing the switch in a relay rack, be sure to install and secure the rack per the rack manu-

facturer’s specifications.

• Refer to page 2-12 for important chassis airflow recommendations before installing.

To rack-mount the switch, follow the steps below:

1 Mark the holes on the rack where the chassis is to be installed.

2 Using two people, lift and position the chassis until the rack-mount flanges are flush with the rack post.

3 Align the holes in the flanges with the rack holes you marked in step 1.

4 Once the holes are aligned, use a third person to insert a screw through the bottom hole on each flange.

Tighten both screws until they are secure.

Chassis and Power Supplies Monitoring Chassis Power

Monitoring Chassis Power

Adding Network Interface (NI) modules and removing power supplies significantly affects the overall power budget for the switch. Therefore, before adding a module or removing a power supply, you must first verify that the current chassis power supports the change.

Refer to the sections below for important information on monitoring the current chassis power.

Checking Chassis Power Before Adding a Module

Depending on the module type, adding a single module can add up to 88 watts to the existing chassis power requirements. The table below shows the requirements for CMM and NI modules currently supported on OS9800, OS9700 and OS9600 switches:

Module Type Power Required, in Watts

OS9800-CMM 88 OS9600/OS9700-CMM 33 OS9-GNI-C24 51 OS9-GNI-P24 54 OS9-GNI-C20L 55 OS9-GNI-C48T 105 OS9-GNI-U24 55 OS9-XNI-U6 77 OS9-XNI-U2 36

Note. Technical specifications for NI modules are provided in Chapter 5, “Network Interface (NI)

Modules.”

As soon as a module is inserted, and the module’s connectors make contact with the chassis backplane, the power requirements take effect. If there is no adequate power, the incoming module will not power on. Additional power errors may also occur, which can interrupt data flow on the switch. Therefore, it is important to manually check the current chassis power before adding a module.

For examples, showing effective ways to check the current chassis power, refer to the examples beginning on page 2-22.

OmniSwitch 9000 Series Hardware Users Guide June 2007 page 2-21

Monitoring Chassis Power Chassis and Power Supplies

Example 1: Adequate Power to Add a Module

1 First, enter the show chassis command. A screen similar to the following displays:

-> show chassis Model Name: OS9700, Description: OS9700, Part Number: 901748-ÿÿÿ, Hardware Revision: 202, Serial Number: 1467014A, Manufacture Date: NOV 16 2005, Admin Status: POWER ON, Operational Status: UP, Free Slots: 8, Power Left: 535, Number Of Resets: 2

Note that the “Power Left” field in the table output shows 535. This value, displayed in watts, indicates that 535 watts are available for additional hardware (e.g., CMM and NI modules).

2 Next, tabulate the power requirements for all modules to be added. For example, let’s say that the

following modules are to be added to the chassis:

• OS9600/OS9700-CMM (33 watts)

• OS9-GNI-C24 (54 watts)

• OS9-XNI-U2 (36 watts)

The total power required for all incoming modules is 231 watts. Even after the 231 watts are allocated to the incoming modules, the chassis will retain 304 unused watts. The modules listed above can be safely added to the chassis.

3 After the modules have been installed, re-enter the show chassis command to confirm the results:

As shown in the display, there are 304 watts of unused power in the chassis power supply budget. In this scenario, there was adequate power to add all NI modules, as well as the OS9600/OS9700-CMM.

page 2-22 OmniSwitch 9000 Series Hardware Users Guide June 2007

Chassis and Power Supplies Monitoring Chassis Power

Example 2: Inadequate Power to Add a Module

1 Enter the show chassis command. A screen similar to the following displays:

Note that the “Power Left” field in the table output shows 40. This value, displayed in watts, indicates that only 40 watts are available for additional hardware.

2 Tabulate the power requirements for the module(s) to be added. For example, let’s say that the

following module is to be added to the chassis:

• OS9-GNI-C24 (54 watts)

As shown, the total power required for the incoming module is 54 watts. If the module is installed, the switch’s power budget will exceed by at least 14 watts. The module will not be power on until:

• One or more modules are removed from the chassis and the switch is rebooted

• An additional power supply is added (if applicable) and the switch is rebooted

OmniSwitch 9000 Series Hardware Users Guide June 2007 page 2-23

Monitoring Chassis Power Chassis and Power Supplies

Note. If a module of the same type is already installed in the chassis, you can use the show ni command to determine the power requirements for the module to be added. For example, if an OS9-GNI-C24 is to be added to the chassis, and there is already an OS9-GNI-C24 installed at slot 8, enter the following command:

-> show module long 8 Module in slot 8 Model Name: OS9-GNI-C24, Description: 24pt 10/100/1000 Mod, Part Number: 901765-10, Hardware Revision: 413, Serial Number: 1453410A, Manufacture Date: NOV 16 2005, Firmware Version: 5, Admin Status: POWER ON, Operational Status: UP, Power Consumption: 54, Power Control Checksum: 0x808, MAC Address: 00:d0:95:6b:0b:30, ASIC - Physical: 0x1901 0x0201 0x0201 0x001e 0x001e 0x001e

Note that the module’s power requirement is 54 watts, as shown in the “Power Consumption” field.

page 2-24 OmniSwitch 9000 Series Hardware Users Guide June 2007

Chassis and Power Supplies Monitoring Chassis Power

Checking Chassis Power Before Shutting Off or Removing a Power Supply

When shutting off or removing a power supply, it is important to remember that you are reducing the amount of watts available for NI and CMM modules. In other words, disabling a power supply significantly affects the switch’s overall power budget.

Before shutting off or removing a power supply, note that an AC power supply provides approximately 480 usable watts. Therefore, when removing a power supply, you must first verify that enough watts will be maintained by the remaining power supplies to support the number of modules installed.

Example 1: Adequate Power to Remove a Power Supply

1 Enter the show chassis command. A screen similar to the following displays:

-> show chassis Model Name: OS9700,

Description: OS9700,

Part Number: 901748-ÿÿÿ,

Hardware Revision: 202, Serial Number: 1467014A, Manufacture Date: NOV 16 2005, Admin Status: POWER ON, Operational Status: UP, Free Slots: 8,

Power Left: 535,

Number Of Resets: 2

In this example, the “Power Left” field displays 535 unused watts. If one power supply is removed, the switch will have 55 unused watts (535 – 480 = 55). This is adequate power to support the current modules installed; one power supply can be safely removed.

2 After the modules have been installed, re-enter the show chassis command to confirm the results:

-> show chassis Model Name: OS9700,

Description: OS9700,

Part Number: 901748-ÿÿÿ,

Hardware Revision: 202, Serial Number: 1467014A, Manufacture Date: NOV 16 2005, Admin Status: POWER ON, Operational Status: UP, Free Slots: 8,

Power Left: 55,

Number Of Resets: 2

Important Power Supply Redundancy Recommendation. It is strongly recommended that the switch maintains power supply redundancy whenever possible. Refer to “Power Supply Redundancy” on

page 2-27 for detailed information on power supply redundancy.

Description: OS9700,

Part Number: 901748-ÿÿÿ,

Hardware Revision: 202, Serial Number: 1467014A, Manufacture Date: NOV 16 2005, Admin Status: POWER ON, Operational Status: UP, Free Slots: 8,

Power Left: 400,

Number Of Resets: 2

In this example, the “Power Left” field displays 400 unused watts. If one power supply is disabled, the switch’s power budget will be exceeded by at least 80 watts (400 – 480 = – 80). If a power supply is shut off or removed for any reason, the switch will automatically power down NI modules until the power budget shortfall has been corrected.

Adding a Power Supply

You can add a power supply to the chassis at any time without disturbing the switch’s network functions. You are not required to power down the switch.

Hot Swapping a Power Supply

Hot swapping a power supply refers to the action of replacing a power supply while the switch is operating. To hot swap a power supply without disrupting switch operations, you must first have power supply redundancy. Otherwise, switch operations may be disrupted.

Permanently Removing a Power Supply

If you plan to permanently remove a power supply from the chassis while the switch is operating, verify that you have effective power supply redundancy before doing so. Otherwise, switch operations may be disrupted.

Additional Information. For instructions on installing and removing power supplies, refer to page 2-28 through page 2-30. For information on power supply redundancy, refer to “Power Supply Redundancy” on

page 2-27.

page 2-26 OmniSwitch 9000 Series Hardware Users Guide June 2007

Chassis and Power Supplies Power Supply Redundancy

Power Supply Redundancy

While the switch is running, all power supplies installed and operating share the electrical load. If a power supply is physically removed from the chassis or fails unexpectedly, the remaining power supplies automatically take up the load without disrupting the switch. However, for this failover to work, you must have at least one redundant power supply installed and running in your switch at all times. Refer to the important information on page 2-18 through page 2-26 to determine minimum switch power requirements, as well as redundant power supply requirements.

Redundancy Defined

Power supply redundancy is defined as having at least one power supply more than the minimum switch requirement.

In the example below, a minimum of two power supplies is required to support the switch’s basic operations (see page 2-18). A third power supply provides failover (i.e., redundancy) if one power supply is physically pulled from the chassis or quits unexpectedly.

Chassis and Power Supplies Power Cords

Power Cords

Because the power cord is the power supply’s main disconnect device, it should be plugged into an easily accessible outlet. In the event that your power cord is lost or damaged, refer to the specifications below.

Specifications

The power cord to be used with 115-Volt configuration is a minimum type SJT (SVT) 14/3, rated at 250 Volts AC, 10 Amps with a maximum length of 15 feet. One end terminates in an IEC 320 attachment plug and the other end terminates in a NEMA 5-15P plug.

The power cord to be used with 230-Volt configuration is minimum type SJT (SVT) 14/3, rated 250 Volts ac, 10 Amps with a maximum length of 15 feet. One end terminates in an IEC 320 attachment plug and the other end terminates as required by the country where it will be installed.

European cords must be Harmonized (HAR) type.

Important. The specified replacement power cord for OmniSwitch 9000 switches is 14-gauge (14/3). Do not use standard 18-gauge (18/3) cords such as those supplied with personal computers.

Redundant AC Circuit Recommendation Chassis and Power Supplies

Redundant AC Circuit Recommendation

If possible, it is recommended that each AC outlet resides on a separate circuit. With redundant AC, if a single circuit fails, the switch’s remaining power supplies (on separate circuits) will likely be unaffected and can therefore continue operating.

Note. The switch must have power supply redundancy for the redundant AC circuit to be effective. Refer to “600 Watt DC-to-DC Power Supply” on page 2-18 for more information.

Chassis and Power Supplies Temperature Management

Grounding the Chassis

The switch has two threaded holes for grounding screws located on the back of the chassis. These holes use 10-32 screws and are approximately one inch apart. These holes are surrounded by a small paint-free rectangular area, which provides metal-to-metal contact for a ground connection.

Use this connector to supplement the ground provided by the AC power cord. To do so, install a Panduit Grounding Lug (type LCD8-10A-L) using 8AWG copper conductors to the paint-free rectangular area. Be sure to use a crimping tool.

Temperature Management

The operating temperature of your switch is an important factor in its overall operability. In order to avoid a temperature-related system failure, your switch must always run at an operating temperature between 0 and 45 degrees Celsius (32

To avoid chassis over-temperature conditions, follow these important guidelines:

1 Be sure that your switch is installed in a well-ventilated environment. To ensure adequate airflow,

allow at least six inches of clearance at the front and back of the chassis. In addition, leave at least two inches of clearance at the left and right sides.

to 113 degrees Fahrenheit).

2 If your switch chassis is not fully populated with NI modules, be sure that blank cover panels are

installed at empty slot positions at all times. Blank cover panels help regulate airflow and thus regulate the overall operating temperature in the switch. Refer to page 2-43 for more information.

Monitoring Chassis Temperature Status. To check the switch’s current temperature status, use the

show temperature command. For example:

-> show temperature Hardware Board Temperature (deg C) = 35, Hardware Cpu Temperature (deg C) = 29, Temperature Upper Threshold Range (deg C) = 30 to 80, Temperature Upper Threshold (deg C) = 60, Temperature Range = UNDER THRESHOLD, Temperature Danger Threshold (deg C) = 80

For more information about these displays, see the “Chassis Management and Monitoring Commands” chapter in the OmniSwitch CLI Reference Guide.

OmniSwitch 9000 Series Hardware Users Guide June 2007 page 2-33

Temperature Management Chassis and Power Supplies

Temperature Errors

The CMM monitors the chassis ambient air temperature at all times via an onboard sensor. If an overtemperature condition occurs, there are two different levels of error severity:

• Warning threshold has been exceeded

• Danger threshold has been exceeded

Warning Threshold

If the temperature exceeds the switch’s user-configurable warning threshold, the CMM sends out a trap. Traps are printed to the console in the form of text error messages. The CMM’s TEMP LED also displays amber, indicating an error. (Refer to Chapter 2, “Chassis and Power Supplies” for CMM front panel descriptions, including status LEDs.)

When the warning threshold has been exceeded, switch operations remain active. However, it is recommended that immediate steps be taken to address the over-temperature condition.

Addressing warning threshold temperature conditions may include:

• Checking for a chassis airflow obstruction

• Checking the ambient room temperature

• Checking the fan tray status using the show fan command. See page page 2-37 for more information.

• Verifying that the warning threshold has not been manually set to an otherwise common or acceptable

ambient temperature—for example, 31

degrees Centigrade. (The default warning threshold is 60C.

This value may be configured using the temp-threshold command. The current set warning threshold may be viewed using the show temperature command.)

Note. Once the ambient air temperature is reduced to below the warning threshold, the CMM’s TEMP LED automatically resets to green.

Danger Threshold

If the chassis ambient air temperature rises above the danger threshold (75 degrees Centigrade for OmniSwitch 9600 switches and 70 degrees Centigrade for OmniSwitch 9700/9800 switches), the switch will power off all Network Interface (NI) modules until the temperature conditions have been addressed and the switch is manually booted. The danger threshold is factory-set and cannot be configured by the user.

Addressing danger threshold temperature conditions may include:

• Checking for a chassis airflow obstruction

• Checking the ambient room temperature

• Checking the fan tray status using the show fan command. See page page 2-37 for more information.

Note. When the danger threshold has been exceeded, the CMM’s TEMP LED will not reset from amber to green until after a system boot.

Chassis and Power Supplies Chassis Fan Tray

Chassis Fan Tray

The OmniSwitch 9700 and OmniSwitch 9800 switches house a single fan tray located at the top-rear of the chassis and at the front-left of the chassis on OmniSwitch 9600. This fan tray consists of three independently-operating fans on OS9700 and OS9800, and four independently-operating fans on OS9600 and is the main temperature control component of the switch. The fan tray provides cooling airflow for all NI modules and CMMs. This airflow is a crucial factor in the switch’s overall operability. Refer to “Chas-

sis Airflow” on page 2-40 for an overview of chassis airflow. Also, refer to page 2-12 for important

airflow considerations.

Chassis and Power Supplies Chassis Fan Tray

Monitoring Fan Tray Status

The CMM constantly monitors fan operation. If any of the switch’s fans unexpectedly shuts down, the CMM sends out a trap and the FAN LED on the CMM’s front panel displays amber.

Note. To check the switch’s current fan tray status, use the show fan command. For example:

-> show fan Fan Status

------+--------------Fan-1 Running Fan-2 Running Fan-3 Running

For more information about these displays, see the “Chassis Management and Monitoring Commands” chapter in the OmniSwitch CLI Reference Guide.

Fan Redundancy

In the event that one fan quits unexpectedly, the remaining fans will continue running; switch operations are not disrupted.

Note. One fan failure needs to be reported immediately to have an RMA unit available, and upon receiving the unit it must be replaced immediately. If no action is taken and a second fan fails, the chassis will shutdown all NIs after one minute and fifteen seconds. For information on emergency replacement of the fan tray, refer to “Hot Swapping the Fan Tray” below.

Storing Backup Fan Trays. It is a good idea to keep at least one backup fan tray in your data facility or other hardware storage area.

Hot Swapping the Fan Tray

As stated previously, the fan tray is the main temperature control component of the switch. As a result, the fan tray should never be removed while the switch is operating unless it is absolutely necessary.

However, if the fan tray requires immediate replacement or service, the fan tray can be hot swapped—i.e., it can be changed out without shutting off the switch.

Important. Hot swapping the fan tray is a time-sensitive procedure. If the fan tray is removed, it must be replaced within one minute and fifteen seconds. Otherwise, overheating will occur, which can lead to

system failure.

For detailed instructions on properly removing and installing a fan tray, refer to page 2-38 through page

Chassis Airflow Chassis and Power Supplies

Chassis Airflow

The fan tray pulls air from the air intake vents located at the bottom-front and left and right sides of the chassis. The air is directed vertically through the chassis’ module compartment and past the NI and CMM circuit boards. Airflow is then exhausted through the fan tray at the top-rear of the chassis.

Important. Maintain a clearance of at least six inches at the front and back of the chassis, as well as at the left and right sides. Otherwise, airflow may become restricted. Restricted airflow can cause your switch to overheat; overheating can lead to switch failure.

Blank Cover Panels and Chassis Airflow

Blank cover panels are provided with your switch and are used to cover empty CMM and NI slots, as well as empty power supply bays. These cover panels play an important role in chassis airflow and temperature management. If your switch is not fully populated and blank cover panels are not installed over empty slot locations, airflow is affected. When blank cover panels are missing, air does not take the direct route from the air intake vents, up through the chassis module compartment, and out through the fan tray. Instead, a portion of the airflow is allowed to be drawn in through the front module compartment of the chassis. As a result, normal airflow is disrupted and an extra task is placed on the fan tray to cool the chassis. Refer to the figure below for more information.

Cover panels also provide protection for module processor boards and other sensitive internal switch components by closing off a chassis that is not fully populated.

Note. Because they regulate airflow and help protect internal chassis components, blank cover panels should be installed over empty module slots and power supply bays at all times.

Missing Cover Panels.

Missing cover panels affect airflow by allowing air to be drawn in through the front module compartment of the chassis. As a result, the direct route from the air intake vents to the fan tray exhaust is disrupted.

For optimal airflow and chassis component protection, always install blank cover panels over empty module slots and power supply bays.

3 Installing and Managing

Power over Ethernet (PoE)

Power over Ethernet (PoE) is supported on OmniSwitch 9600, 9700, and 9800 switches and provides inline power directly from the switch’s Ethernet ports. Powered Devices (PDs) such as IP phones, wireless LAN stations, Ethernet hubs, and other access points can be plugged directly into the Ethernet ports. From these RJ-45 ports, provided on Alcatel-Lucent’s OS9-GNI-P24 modules, the devices receive both electrical power and data flow.

Since the feature reduces devices’ dependence on conventional power sources, PoE eliminates many restrictions that traditional electrical considerations have imposed on networks.

In a PoE configuration, power source equipment (PSE) detects the presence of a PD and provides an electrical current that is conducted along the data cable. The PD operates using the power received via the Ethernet data cable; no connection to an additional power source (e.g., an AC wall socket) is required.

Note on Terminology. There are several general terms used to describe this feature. The terms Power over Ethernet (PoE), Power over LAN (PoL), Power on LAN (PoL), and Inline Power are synonymous

terms used to describe the powering of attached devices via Ethernet ports. For consistency, this chapter and the OmniSwitch CLI Reference Guide refer to the feature as Power over Ethernet (PoE).

Additional terms, such as Powered Device (PD) and Power Source Equipment (PSE) are terms that are not synonymous with PoE, but are directly related to the feature:

• PD refers to any attached device that uses a PoE data cable as its only source of power. Examples

include access points such as IP telephones, Ethernet hubs, wireless LAN stations, etc.

• PSE refers to the actual hardware source of the electrical current for PoE. In the case of OS9600,

OS9700, and OS9800 switches, the PSE is the peripheral power shelf unit; 510W and 360W power supplies are exclusive for the OS9600 only.

Power over Ethernet Application Example

The diagram above shows the power path from a conventional power source—e.g., an Uninterruptible Power Source (UPS)—to attached powered devices (PDs) located in a separate area of the building or campus. PDs include IP telephones and wireless LAN devices.

Important. Alcatel-Lucent recommends that PoE-enabled switches with attached IP telephones should have operational power supply redundancy at all times for 911 emergency requirements. In addition, both the chassis and the power shelf should be plugged into an Uninterruptible Power Source (UPS).

The items listed below (1–5) describe the major components and connections in the application example. Refer to the corresponding numbers (1–5) in the diagram above for specific locations of these major components and connections.

1 The power supplies in the OS9800 chassis are plugged into an AC power source located in the

Building One data center. These power supplies provide power for basic switch operations.

2 Also in the Building One data center, an OS-IP-SHELF is attached to the OS9800 via DB-25

chassis-to-power-shelf cables. (Connections for the chassis-to-power-shelf cables are located on the rear panel of the switch chassis, as well as the rear panel of the separate OS-IP-SHELF.)

page 3-4 OmniSwitch 9000 Series Hardware Users Guide June 2007

Installing and Managing Power over Ethernet (PoE) Power over Ethernet Overview

3 The power shelf includes four power supply bays of its own. These power supplies provide inline

power through the switch’s backplane to the Ethernet ports located on OS9-GNI-P24 modules. The power supplies in the OS-IP-SHELF are plugged into an AC power source in the Building One data center.

Note. PoE is supported only on Ethernet ports in OS9-GNI-P24 modules.

4 Standard Category 5 Ethernet cables are connected to the RJ-45 ports on the switch’s OS9-GNI-P24

module. Like many typical campus network layouts, the Ethernet cable runs from the data center to a separate building nearby. (The maximum cable distance is approximately 100 meters.)

5 The Ethernet cables are then plugged into PDs (i.e., IP telephones and wireless LAN devices), which

are used by operators and staff in the adjacent Building Two. Both electrical power and data flow are provided via these standard Category 5 Ethernet cables. No additional AC power source (such as a 110V wall socket) is required for any of these attached PDs.

Note. Because OS9-GNI-P24 modules fully support 10/100/1000 Ethernet connectivity, you may also attach non-PD equipment—such as computer workstations, printers, servers, etc.—to the OS9-GNI-P24 ports. See Chapter 5, “Network Interface (NI) Modules,” for more information on the OS9-GNI-P24.

OS-IP-SHELF PoE Power Shelf

The OS-IP-SHELF unit is the chassis’ peripheral power shelf, which provides the electrical current used for PoE ports. The OS-IP-SHELF contains up to four load sharing power supply modules can be used for a maximum of 2400W PoE power source. Redundancy is supported when two modules are in use.

Note. Use the appropriate Power Cable(s) provided by Alcatel-Lucent with the OS-IP-SHELF power supplies.

Note. You must not connect OS-IP-SHELF at the same time a 510W/360W power supply is plugged in and vice versa on the OS9600. There is a rotating plate on the back of the OS9600 chassis that prevents the OS-IP-SHELF and 510W/360W power supplies from being connected at the same time. The 510W/360W power supplies cannot be used on the OS9700 or OS9800 switches.

The OS-IP-SHELF must be properly connected to the chassis and fully operational for PoE to function. For information on setting up the OS-IP-SHELF, refer to the sections below:

510W/360W Power Supply

The 510W and 360W power supplies can be used as an alternate power source for PoE. A single 510W power supply allocates 390W for the PoE functionality; Similarly, a single 360W power supply allocates 240W for the PoE functionality. Only one power supply module can be installed per switch, not both. These power modules do not support load sharing.

Note. The 360W/510W power supplies are only supported on OS9600 switches and not on OS9700/ OS9800 switches.

Note. Use the appropriate Power Cable(s) provided by Alcatel-Lucent with the 360W/510W power supplies.

Note. You must not connect OS-IP-SHELF at the same time a 510W/360W power supply is plugged in.

Installing and Managing Power over Ethernet (PoE) Power Shelf and PoE Port Guidelines

Power Shelf and PoE Port Guidelines

The tables below list PoE power support for both non-redundant and redundant power supply configurations.

Note. PoE power supply redundancy is not related to the switch’s chassis power supply redundancy. For information on chassis power supply redundancy and minimum power requirements for switch operations, refer to the “Chassis and Power Supplies” chapter.

Non-Redundant Power Supply Configurations

Use the table below to determine the minimum number of power supplies needed in a non-redundant PoE configuration.

Power Supplies Power

1600 watts 2 1200 watts 3 1800 watts 4 2400 watts

For example, a PoE configuration with 192 powered devices, each requiring 7 watts of power, uses a total of 1344 watts. Because two power supplies support up to 1200 watts only, a total of three power supplies is required for this non-redundant 1344 watt PoE application.

OmniSwitch 9000 Series Hardware Users Guide June 2007 page 3-9

Power Shelf and PoE Port Guidelines Installing and Managing Power over Ethernet (PoE)

Redundant Power Supply Configurations

Power supply redundancy is defined as having at least one power supply more than the minimum requirement (i.e., N+1). With redundancy, if a power supply is removed from the power shelf or fails unexpectedly, the remaining power supplies automatically take up the load without disrupting PoE support.

Use the table below to determine the minimum number of power supplies needed in a redundant PoE configuration

Power Supplies Power

1+1 600 watts 2+1 1200 watts

For example, a PoE configuration with 92 powered devices, each requiring 7.5 watts of power, uses a total of 690 watts. Because 1+1 power supplies support up to 600 watts only, a configuration of 2+1 is required for this application.

Installing and Managing Power over Ethernet (PoE) Setting Up Power over Ethernet Hardware

Setting Up Power over Ethernet Hardware

Setting up PoE hardware involves the following general steps:

• Positioning the Power Shelf on page 3-11

• Installing the Power Supplies on page 3-15

• Connecting the Power Shelf to the Chassis on page 3-19

• Connecting Powered Devices on page 3-22

Note. Before beginning these steps, be sure to review the basic guidelines outlined below.

Basic Guidelines for Setting Up PoE Hardware

Positioning the Power Shelf

When positioning the power shelf for installation, please note the following important guidelines:

• In free-standing (i.e., non-rack-mounted) installations, the power shelf cannot support the weight of a

switch chassis. As a result, do not attempt to stack an OS9600, OS9700, or OS9800 chassis directly on top of the power shelf at any time; damage to the power shelf chassis and its components may result. For free-standing installations, the power shelf must either be placed on top of, or alongside, the switch chassis.

• The cables connecting the power shelf to the chassis are approximately 49 inches in length. When

positioning the power shelf for installation, be sure that the unit is close enough to the OS9600, OS9700, or OS9800 chassis to provide a connection.

• For rack-mounted installations, the power shelf may be installed either above or below the switch

chassis.

OmniSwitch 9000 Series Hardware Users Guide June 2007 page 3-11

Setting Up Power over Ethernet Hardware Installing and Managing Power over Ethernet (PoE)

Rack-Mounting the Power Shelf

Refer to the important guidelines below before installing the power shelf in a rack.

• If the power shelf was not shipped with power supplies installed, it is recommended that you install the

power supplies after you have rack mounted the switch. This will minimize the weight of the chassis when positioning and installing the power shelf. For detailed information on installing power supplies, refer to page 3-15.

• It is recommended that two people install the power shelf in the rack—one person to hold the unit and

position it in the rack, and a second person to secure the unit to the rack using the rack attachment screws (not provided).

• Alcatel-Lucent provides two rack-mount flanges with each power shelf. These flanges support standard

19-inch rack mount installations. These flanges must be attached to the power shelf before the power shelf can be rack mounted.

Note. If you are installing the power shelf in a 23-inch wide rack, Alcatel-Lucent offers optional 23-inch rack-mounting hardware. For more information, contact your Alcatel-Lucent representative.

• Alcatel-Lucent does not provide rack-mount screws. Use the screws supplied by the rack vendor.

• To prevent a rack from becoming top heavy, it is recommended that you install heavier equipment at

the bottom of the rack whenever possible.

• If you are installing the power shelf in a relay rack, be sure to install and secure the rack per the rack

manufacturer’s specifications.

Enabling PoE

By default, Power over Ethernet is administratively enabled in the switch’s system software. However, in order to physically activate PoE, you must issue the lanpower start command on a slot-by-slot basis before any connected PDs will receive inline power.

To activate power to PoE-capable ports in a slot, enter the corresponding slot number only. For example:

-> lanpower start 3

Note. You cannot activate PoE for more than one slot at a time. Also, a valid PoE module (OS9-GNI-P24) must be installed in the corresponding slot position.

OmniSwitch 9000 Series Hardware Users Guide June 2007 page 3-23

Configuring Power over Ethernet Parameters Installing and Managing Power over Ethernet (PoE)

If power to a particular port has been disconnected via the lanpower stop command, you can reactivate power to the port by specifying both the slot and port in the command line. For example:

-> lanpower start 3/11

Note. You cannot use the slot/port syntax to initially activate PoE on a port. This syntax is intended only to reactivate power to those ports that have been disconnected via the lanpower stop command. To initially activate PoE, you must use the lanpower start slot syntax only, as described above.

Disabling PoE

To disable PoE on a particular slot or port, use the lanpower stop command.

To disable PoE on a specific PoE-capable port, enter a slot/port number. For example:

-> lanpower stop 9/22

To disable PoE for all PoE-capable ports in a slot, enter the corresponding slot number only. For example:

-> lanpower stop 9

Configuring the Total Power Allocated to a Port

Each port is authorized by the system software to use up to a maximum of 18000 milliwatts to power any attached device.

You can either increase or decrease this value. Values may range from 3000 to 18000 milliwatts.

Increasing the total power allocated to an individual port may provide a more demanding Powered Device (PD) with additional power required for operation. Decreasing the total power allocated to a port helps preserve inline power and assists in the overall management of the switch’s power budget.

To increase or decrease the total power allocated to an individual port, use the lanpower power command. Because you are setting the power allowance for an individual port, you must specify a slot/port number in the command line. For example, the syntax

-> lanpower 3/12 power 3000

reduces the power allowance on port 12 of the OS9-GNI-P24 module installed in slot 3 to 3000 milliwatts. This new value is now the maximum amount of power the port can use to power any attached device (until the value is modified by the user).

Configuring the Total Power Allocated to a Slot

Like the maximum port power allowance, the system software also provides a maximum slot-wide power allowance. The switch allocates 260 watts for each slot installed in the OS9600, OS9700 or OS9800 chassis. However, when the 360W/510W power supply is used, the OS9600 will allocate 240W/390W. respectively. In other words, each slot is authorized by the system software to use up to either 240 or 390 watts to power all devices connected to its ports depending on the power supply used.

As with the maximum port power allowance, the user can either increase or decrease this value. Values may range from 37 to 260 watts.

Installing and Managing Power over Ethernet (PoE) Configuring Power over Ethernet Parameters

Increasing the total power allocated to a slot may provide more demanding Powered Devices (PDs) with additional power required for operation. Decreasing the total power allocated to a slot helps preserve inline power and assists in the overall management of the switch’s power budget.

Important. Before changing the maximum slot-wide power allowance, you must disable PoE for the slot via the lanpower stop command. Once the new value is assigned, re-enable PoE for the slot via the

lanpower start command.

To increase or decrease the total power allocated to a slot, use the lanpower maxpower command. Because you are setting the power allowance for an individual slot, you must specify a slot number in the command line. For example, the syntax

-> lanpower 3 maxpower 80

reduces the power allowance of the OS9-GNI-P24 module installed in slot 3 to 80 watts. This value is now the maximum amount of power the slot can use to power all attached devices (until the value is modified by the user).

Setting Port Priority Levels

Because not all Powered Devices (PDs) connected to the switch have the same priority within a customer network setting, OS9600/OS9700/OS9800 switches allow the user to specify priority levels on a port-byport basis. Priority levels include low, high, and critical.

• Low. This default value is used for port(s) that have low-priority devices attached. In the event of a

power management issue, inline power to low-priority ports is interrupted first (i.e., before critical and high-priority ports).

• High. This value is used for port(s) that have important, but not mission-critical, devices attached. If

other ports in the chassis have been configured as critical, inline power to high-priority ports is given second priority.

• Critical. This value is used for port(s) that have mission-critical devices attached, and therefore require

top (i.e., critical) priority. In the event of a power management issue, inline power to critical ports is maintained as long as possible.

To change the priority level for a particular port, use the lanpower priority command. Because the switch allows you to set priority levels on a port-by-port basis, be sure to specify slot/port information in the command line. For example, the syntax

-> lanpower 8/22 priority critical

changes the priority value of port 22 of the OS9-GNI-P24 module installed in slot 8 to the highest priority level of critical. Now that the default value has been reconfigured, this port should be reserved for those PDs that are mission critical for network operations.

Setting PoE Redundancy Status

The PoE feature has built-in hardware redundancy. PoE power redundancy status can be configured by the user. Redundancy is disabled by default. To enable the feature, use the lanpower redundant-power command. Enter the keyword enable in the command line, as shown:

-> lanpower redundant-power enable

To disable the feature, use the keyword disable in the command line:

-> lanpower redundant-power disable

Important. In order to comply with 911 emergency requirements, PoE power redundancy status must be

enabled at all times.

Note. For information on the priority disconnect function, refer to “Understanding Priority Disconnect” on

page 3-27.

Setting the Capacitor Detection Method

To enable the PowerDsine capacitor detection method use the lanpower capacitor-detection command by entering lanpower capacitor-detection followed by the slot number of the OS9-GNI-P24 and enable.

For example, to enable the capacitor detection method on the OS9-GNI-P24 with slot number 2 enter:

-> lanpower 2 capacitor-detection enable

To disable it use the lanpower capacitor-detection command by entering lanpower capacitor-detection followed by the slot number of the OS9-GNI-P24 and disable.

For example, to disable the capacitor detection method on the OS9-GNI-P24 with slot number 2 enter:

-> lanpower 2 capacitor-detection disable

Note. The capacitive detection method should only be enabled to support legacy IP phones only—this feature is not compatible with IEEE specification 802.3af. Please contact your Alcatel-Lucent sales engineer or Customer Support representative to find out which Alcatel-Lucent IP phone model needs capacitive detection enabled.

Installing and Managing Power over Ethernet (PoE) Understanding Priority Disconnect

Understanding Priority Disconnect

The priority disconnect function differs from the port priority function described on page 3-25 in that it applies only to the addition of powered devices (PDs) in tight power budget conditions. Priority disconnect is used by the system software in determining whether an incoming PD will be granted or denied power when there are too few watts remaining in the PoE power budget for an additional device. For example, if there are only 2 watts available in the current PoE power budget and a user plugs a 3.5W powered device into a PoE port, the system software must determine whether the device will be powered on. Based on priority disconnect rules, in some cases one or more existing devices may be powered down in order to accommodate the incoming device. In other cases, the incoming device will be denied power.

Priority disconnect rules involve the port priority status of an incoming device (i.e., low, high, and critical), as well as the port’s physical port number (i.e., 1–24). Understanding priority disconnect rules is especially helpful in avoiding power budget deficits and the unintentional shutdown of mission-critical devices when PDs are being added in tight power budget conditions. For detailed information on how priority disconnect uses port priority and port number criteria for determining the power status of incoming PDs, refer to the illustrated examples on pages 3-28 through 3-31.

Reminder. Priority disconnect only applies when there is inadequate power remaining in the power budget for an incoming device.

For information setting the priority disconnect status, refer to the section below. For information on setting the port priority status (a separate function from priority disconnect), refer to “Setting Port Priority

Levels” on page 3-25.

Setting Priority Disconnect Status

By default, priority disconnect is enabled in the switch’s system software. For information on changing the priority disconnect status, refer to the information below.

Disabling Priority Disconnect

When priority disconnect is disabled and there is inadequate power in the budget for an additional device, power will be denied to any incoming PD, regardless of its port priority status (i.e., low, high, and critical) or physical port number (i.e., 1–24).

To disable priority disconnect, use the lanpower priority-disconnect command. Because the switch allows you to set priority disconnect status on a slot-by-slot basis, be sure to specify the slot number in the command line. For example, the syntax

-> lanpower 2 priority-disconnect disable

disables the priority disconnect function on the OS9-GNI-P24 module installed in slot 2.

Enabling Priority Disconnect

To enable priority disconnect, use the lanpower priority-disconnect command. Be sure to specify the slot number in the command line. For example, the syntax

-> lanpower 9 priority-disconnect enable

enables priority disconnect on the OS9-GNI-P24 module installed in slot 9.

OmniSwitch 9000 Series Hardware Users Guide June 2007 page 3-27

Understanding Priority Disconnect Installing and Managing Power over Ethernet (PoE)

Priority Disconnect is Enabled; Same Priority Level on All PD Ports

Reminder. Priority disconnect examples are only applicable when there is inadequate power remaining to power an incoming device.

When a PD is being connected to a port with the same priority level as all other ports in the slot, the physi- cal port number is used to determine whether the incoming PD will be granted or denied power. Lowernumbered ports receive higher priority than higher-numbered ports. In other words, a PD connected to Port 1 will have a higher power priority than a PD connected to Port 2; a PD connected to Port 23 will have a higher power priority than a PD connected to Port 24. In order to avoid a power budget deficit, another port in the slot is disconnected. In determining which port to power off, the system software disconnects the port with the highest physical port number.

In the example below, there are only 2 watts available in the current PoE power budget. When the additional 3.5W powered device is added to the configuration, the system software must determine whether the device will be granted or denied power. Because the incoming device is being connected to a lowernumbered physical port, it receives higher priority over the existing PDs and is granted power. Meanwhile, to avoid a deficit in the power budget, the PD connected to the highest physical port number (in this case, Port 18) is disconnected.

Installing and Managing Power over Ethernet (PoE) Understanding Priority Disconnect

Priority Disconnect is Enabled; Incoming PD Port has Highest Priority Level

Reminder. Priority disconnect examples are only applicable when there is inadequate power remaining to power an incoming device.

When a PD is being connected to a port with a higher priority level than all other ports in the slot, the incoming PD will automatically be granted power over the other devices, regardless of its physical port number.

In order to avoid a power budget deficit, another port in the slot is disconnected. In determining which port to power off, the system software first selects the port with the lowest configured priority level. For example, if a critical priority device is being added to a slot in which five existing devices are attached to high priority ports and one device is attached to a low priority port, the low priority port is automatically disconnected, regardless of its physical port number.

If all existing devices are attached to ports with the same lower priority level, the system software disconnects the port with both the lowest priority level and the highest physical port number. For example, if a critical priority device is being added to a slot in which six existing devices are attached to high priority ports, the high priority port with the highest physical port number is automatically disconnected.

In the example below, there are only 2 watts available in the current PoE power budget. When the additional 3.5W powered device is added to the configuration, the system software must determine whether the device will be granted or denied power. Because the incoming device is being connected to a critical priority port, and all existing devices are connected to high priority ports, one of the high priority ports must disconnect in order to accommodate the incoming critical device. According to the priority disconnect rules outlined above, the system software selects the port with the lowest priority level and the highest physical port number. In this example, Port 12 is disconnected.

Reminder. Priority disconnect examples are only applicable when there is inadequate power remaining to power an incoming device.

When a PD is being connected to a port with a lower priority level than all other ports in the slot, the incoming PD will be denied power, regardless of its physical port number. Devices connected to other higher-priority ports will continue operating without interruption.

In the example below, there are only 2 watts available in the current PoE power budget. When the additional 3.5W powered device is added to the configuration, the system software must determine whether the device will be granted or denied power. Because the incoming device is being connected to a high priority port, and all existing devices are connected to critical priority ports, the incoming high-priority PD is denied power; meanwhile, the critical priority devices remain powered on. This ensures that no power budget deficit occurs and that higher priority devices (e.g., mission-critical IP phones) are allowed to operate without interruption.

Reminder. Priority disconnect examples are only applicable when there is inadequate power remaining to power an incoming device.

When priority disconnect is disabled, power will be denied to any incoming PD, regardless of its port priority status (i.e., low, high, and critical) or physical port number (i.e., 1–24).

In the example below, there are only 2 watts available in the current PoE power budget. An incoming PD requiring 3.5W is being attached to a critical priority port. All existing PDs are attached to low priority ports. If priority disconnect was enabled (the default setting), the incoming device would easily have power priority over all other connected devices. However, because priority disconnect status is disabled in this example, any incoming PD is denied power, regardless of its priority level. The incoming 3.5W device remains powered off. The existing devices connected to low-priority ports continue operating without interruption.

Monitoring Power over Ethernet via the CLI Installing and Managing Power over Ethernet (PoE)

Monitoring Power over Ethernet via the CLI

To monitor current PoE statistics and settings, use the show lanpower command. The command output displays a list of all current PoE-capable ports, along with the following information for each port:

• Maximum power allocated to the port, in milliwatts

• Actual power used by the port

• Current port status

• Power priority status

• Power on/off status

Aggregate slot and chassis management information also displays. This information includes:

• Maximum watts allocated to the corresponding slot

• Amount of power budget remaining that can be allocated for PoE modules

• Total amount of power remaining that can be allocated for additional switch functions

• Number of power supplies installed and operating in the power shelf

When entering the show lanpower command, you must include a valid slot number in the command line syntax. For example:

-> show lanpower 3 Port Maximum(mW) Actual Used(mW) Status Priority On/Off

Power over Ethernet Tutorial Installing and Managing Power over Ethernet (PoE)

Power over Ethernet Tutorial

The following tutorial provides information in a sample scenario for the following PoE configuration steps:

• Activating power to two slots

• Disconnecting power to a particular port in the slot

• Allocating additional power to an individual device

• Increasing a port’s overall priority level within the PoE configuration

• Reducing the maximum overall power allocated to all ports in a slot

• Verifying configuration changes and the overall PoE power budget

1 Begin by activating PoE on two separate slots. Note that each slot must be activated separately.

For example:

-> lanpower start 3

-> lanpower start 4

2 Disconnect power to one of the ports in slot 3. For this example, port 13:

-> lanpower stop 3/13

3 In this example, a new wireless LAN device is being added to port 3/12. The wireless LAN device

being added requires a minimum of 16000 milliwatts for operation. By default, OS9-GNI-P24 ports have a power allowance of 15400 milliwatts. Therefore the power allowance for the port must be increased, as shown:

-> lanpower 3/12 power 16000

Note. Any milliwatt surplus provides additional overhead in the event of a power spike on the new wireless LAN device.

4 Also, this new wireless LAN device will undergo critical testing within the network. Unexpected

downtime should be avoided at all costs. Therefore, the priority value for the corresponding port must be increased to critical:

-> lanpower 3/12 priority critical

page 3-34 OmniSwitch 9000 Series Hardware Users Guide June 2007

Installing and Managing Power over Ethernet (PoE) Power over Ethernet Tutorial

5 Verify all changes made to port 3/12:

-> show lanpower 3 Port Maximum(mW) Actual Used(mW) Status Priority On/Off

----+-----------+---------------+--------------------+---------+----- 1 15400 3000 Powered On Low ON 2 15400 3000 Powered On Low ON 3 15400 3000 Powered On Low ON 4 15400 3000 Powered On Low ON 5 15400 3000 Powered On Low ON 6 15400 3000 Powered On Low ON 7 15400 3000 Powered On Low ON 8 15400 3000 Powered On Low ON 9 15400 3000 Powered On Low ON 10 15400 3000 Powered On Low ON 11 15400 3000 Powered On Low ON 12 16000 3000 Powered On Critical ON 13 15400 3000 Powered Off Low ON

(Additional output not shown)

Note that the operational status for port 3/12 is on. Also, the maximum power allowance has been increased to 16000, and the port priority status is critical. Port 3/12 is now ready for the new wireless LAN device to be added.

6 To further manage the power budget on the switch, the user can reduce the maximum power allow-

ance on another OS9-GNI-P24 installed in the chassis (in this case, the module installed in slot 4).

The default value for a PoE-capable slot is 260 watts. For this example, the maximum power allowance will be reduced to 70 watts in order to conserve the PoE power budget:

-> lanpower 4 maxpower 70

7 Verify the changes made to slot 4:

-> show lanpower 4

(Initial output not shown)

Slot 4 Max Watts 70 364 Watts Total Power Budget Remaining 514 Watts Total Power Budget Available 1 Power Shelf Power Supplies Available

Note that the maximum power allowance for slot 4 is 70 watts, as specified at step 5. By reducing the power allowance for all ports in this slot, PoE power is conserved. A high-use PoE slot (e.g., slot 3) will have an increased power budget from which to draw necessary power for incoming PDs.
