same rack cabinet. Do not plug a power cord from a device installed in one rack cabinet into a power device installed in a different rack cabinet.

v An electrical outlet that is not correctly wired could place hazardous voltage on

the metal parts of the system or the devices that attach to the system. It is the responsibility of the customer to ensure that the outlet is correctly wired and grounded to prevent an electrical shock.

(R001 part 1 of 2) CAUTION:

v Do not install a unit in a rack where the internal rack ambient temperatures will

exceed the manufacturer’s recommended ambient temperature for all your rack-mounted devices.

v Do not install a unit in a rack where the air flow is compromised. Ensure that air

flow is not blocked or reduced on any side, front, or back of a unit used for air flow through the unit.

v Consideration should be given to the connection of the equipment to the supply

circuit so that overloading of the circuits does not compromise the supply wiring or overcurrent protection. To provide the correct power connection to a rack, refer to the rating labels located on the equipment in the rack to determine the total power requirement of the supply circuit.

v (For sliding drawers) Do not pull out or install any drawer or feature if the rack

stabilizer brackets are not attached to the rack. Do not pull out more than one drawer at a time. The rack might become unstable if you pull out more than one drawer at a time.

v (For fixed drawers) This drawer is a fixed drawer and must not be moved for

servicing unless specified by the manufacturer. Attempting to move the drawer partially or completely out of the rack might cause the rack to become unstable or cause the drawer to fall out of the rack.

Rack relocation (19″ rack)

CAUTION: Removing components from the upper positions in the rack cabinet improves rack stability during relocation. Follow these general guidelines whenever you relocate a populated rack cabinet within a room or building:

v Reduce the weight of the rack cabinet by removing equipment starting at

the top of the rack cabinet. When possible, restore the rack cabinet to the configuration of the rack cabinet as you received it. If this configuration is not known, you must do the following:

– Remove all devices in the 32U position and above. – Ensure that the heaviest devices are installed in the bottom of the rack

cabinet.

– Ensure that there are no empty U-levels between devices installed in the

rack cabinet below the 32U level.

– If the rack cabinet you are relocating is part of a suite of rack cabinets,

detach the rack cabinet from the suite.

– Inspect the route that you plan to take when moving the rack to

eliminate potential hazards.

– Verify that the route that you choose can support the weight of the

loaded rack cabinet. Refer to the documentation that came with your

rack cabinet for the weight of a loaded rack cabinet. – Verify that all door openings are at least 760 x 2030 mm (30 x 80 in.). – Ensure that all devices, shelves, drawers, doors, and cables are secure. – Ensure that the four leveling pads are raised to their highest position. – Ensure that there is no stabilizer bracket installed on the rack cabinet

during movement. – Do not use a ramp inclined at more than 10 degrees. – Once the rack cabinet is in the new location, do the following:

- Lower the four leveling pads.

- Install stabilizer brackets on the rack cabinet.

- If you removed any devices from the rack cabinet, repopulate the rack cabinet from the lowest position to the highest position.

– If a long distance relocation is required, restore the rack cabinet to the

configuration of the rack cabinet as you received it. Pack the rack cabinet in the original packaging material, or equivalent. Also, lower the leveling pads to raise the casters off of the pallet and bolt the rack cabinet to the pallet.

2 Ethernet Switch s-series Installation and User Guide

Chapter 2. Product Overview

This chapter contains an overview of the IBM Ethernet Switch B08S and B16S Layer 2 and Layer 3 switches. Designed for medium to large enterprise backbones, these devices are modular switches that provide the enterprise network with a complete end-to-end Enterprise LAN solution, ranging from the wiring closet to the LAN backbone.

Through the remainder of this guide, these products will be referred to as the B08S and the B16S. When reference to a specific model is not required, the general terms switch, product, or device will be used to refer to all the models. The term s-series may also be used to collectively refer to these switch products.

Hardware benefits

The s-series switches provide the following benefits: v The management module is non-blocking, with a adjustable switch fabric module

and twelve combination Gigabit Ethernet (GbE) copper or fiber ports that provide connectivity to your existing management network.

v The management modules have a console port and a 10/100/1000 port that

provide connectivity to your existing management network. The management modules optionally support 2-port 10-GbE ports or 8-port GbE fiber and copper ports.

v The management modules are interchangeable between the IBM Ethernet Switch

s-series models. However, you cannot mix IPv4 and IPv6 modules together in the same chassis.

v Optional dual management modules provide 100% redundancy. v The crossbar (xbar) architecture enables the management module to switch 30

Gigabits per second between each interface module and within the management module.

v The interface modules and power supplies are interchangeable between the IBM

Ethernet Switch s-series models. However, you cannot mix IPv4 and IPv6 modules together in the same chassis.

v The management, switch fabric, and interface modules are hot swappable, which

means you can remove and replace them while the chassis is powered on and running.

v The devices have a passive backplane. v Completely separate data and control planes, which results in uncompromised

switching performance, increased reliability of both planes, and increased security of the control plane in the event of a Denial of Service (DoS) attack on the data plane.

v Distributed data and control planes, which results in uncompromised wire-speed

performance for the data plane and faster and more efficient performance of management functions for the control plane.

POE port density

Table 2 details the maximum number of POE class 3 (15.4W) ports allowed per power supply used.

maximum of 384 POE ports.

Supported configurations

Standard devices support Layer 2 and base Layer 3 switching. All standard devices can be upgraded to full Layer 3 multiprotocol routing through the purchase of an upgrade feature, at which time they are considered to be premium devices.

The IBM Ethernet Switch s-series can be configured with either all IPv4 management and IPv4 interface modules, or all IPv6 management and IPv6 interface modules. You cannot mix IPv4 and IPv6 modules within a chassis.

Depending on the type of management module installed in the device, IPv6 premium devices support either:

v IPv4 multiprotocol routing and IPv6 host and management features, or v IPv6 and IPv4 multiprotocol routing and IPv6 host and management features

The devices optionally support Power over Ethernet (POE), providing the means for integrating data, voice, and video over existing Ethernet cables.

4 Ethernet Switch s-series Installation and User Guide

Power over Ethernet (POE) applications

B08S and B16S devices with Power over Ethernet (POE) are compliant with the standards described in the IEEE 802.3af specification for delivering in-line power. The 802.3af specification defines the standard for delivering power over existing network cabling infrastructure, enabling multicast-enabled full streaming audio and video applications for the following converged services:

v Voice over IP (VoIP) v WLAN access points v IP surveillance cameras v IP technology devices

POE technology eliminates the need for an electrical outlet and dedicated UPS near IP powered devices. With POE power sourcing devices, power is consolidated and centralized in the wiring closets, improving the reliability and resiliency of the network. Because POE can provide power over Ethernet cable, power is continuous, even in the event of a power failure.

For POE port density, see “POE port density” on page 4.

For more information about POE and how to configure it, see the Configuration Guide.

Support for IPv6 modules

The B08S and B16S support IPv6 management and interface modules starting with software release 04.0.00.

For details about IPv6 modules, see the following sections in this chapter:

v “IPv6 hardware support guidelines” v “Hardware features” v “Interface modules” on page 13

IPv6 hardware support guidelines

Note the following guidelines and restrictions with IPv6 Management and Interface modules:

v IPv4 interface modules must only be matched with IPv4 management modules

and IPv4 interface modules within the same chassis.

v If you install dual IPv6 management modules, the modules must be identical. For

example, you cannot install one 2-port management module and one 8-port management module together in the same chassis. The modules must be of like-kind.

Hardware features

The s-series switches include the following major hardware components:

v Chassis v Management module with optional support for dual management modules that

Enhanced Hot Swap is supported, meaning you can remove and replace the interface modules without powering down the system, and without executing the disable module command. However, it is recommended that the modules be disabled through the CLI before removal from the chassis.

Chapter 2. Product Overview 13

Attention: It is important to wait a minimum of 10 seconds between the removal and insertion of a line module. Re-insertion of a line module less than 10 seconds after the removal of a line module may result in the line module not being properly recognized.

See “Replacing an interface module” on page 97 for instructions.

24-port 10/100/1000 Mbps Ethernet RJ45 copper interface module

The 24-port 10/100/1000 Mbps Ethernet RJ45 copper interface module has twenty-four 10/100/1000 ports with RJ-45 connectors for Cat5 cabling. The copper ports support automatic MDI/MDIX detection, and use auto-sensing and auto-negotiating to determine the speed (10, 100, or 1000 Mbps) and duplex mode (full-duplex or half-duplex) of the port at the other end of the link, and adjust the port accordingly. Ports operating at 1000 Mbps operate in the full-duplex mode only and cannot be modified.

This interface module supports Power over Ethernet (POE).

18 Ethernet Switch s-series Installation and User Guide

v Non-POE devices:

– The 12-volt AC power supplies (also called system (SYS) power supplies)

provide power to one management module and up to eight non-POE interface modules. In the B08S, you can install a second 12-volt power supply for redundancy. The B16S comes with and requires two 12-volt power supplies and supports up to four 12-volt power supplies for redundancy.

v POE devices:

– The 12-volt AC power supplies (also called system (SYS) power supplies)

provide power to the management module, all non-POE interface modules (if applicable), and all ports on POE modules that do not require POE power or to which no power-consuming devices are attached. In the B08S you can install a second 12-volt power supply for redundancy. The B16S comes with and requires two 12-volt power supplies and supports up to four 12-volt power supplies for redundancy.

– The 1250 W 48-volt POE power supplies provide power to the POE daughter

card, and ultimately to POE power-consuming devices. The number of POE power-consuming devices that one 48-volt power supply can support depends on the number of watts required by each power-consuming device. Each 48-volt power supply can provide a maximum of 1080 watts of POE power, and each POE port supports a maximum of 15.4 watts of power per POE power-consuming device. for example, if each POE power-consuming device attached to the IBM device consumes 15.4 watts of power, one 48-volt supply will power up to 70 POE ports. You can install a second 48-volt supply for additional POE power.

– The 48-volt (220-volt input only) POE power supplies provide power to the

POE daughter card, and ultimately to POE power-consuming devices. The number of POE power-consuming devices that one 220-volt power supply can support depends on the number of watts required by each power-consuming device. Each 220-volt power supply can provide a maximum of 2160 watts of POE power, and each POE port supports a maximum of 15.4 watts of power per POE power-consuming device. For example, if each POE power-consuming device attached to the device consumes 15.4 watts of power, one 220-volt supply will power up to 140 POE ports. You can install a second 220-volt supply for additional POE power.

Note: The system powers on as many POE ports as the 48-volt POE power

supplies can handle. The system calculates the maximum number of POE ports it can support based on the number of POE power supplies installed. POE ports are enabled based on their priority settings. Keep in mind that the system will reserve the maximum configured power per POE-enabled port, even if the POE power-consuming device is drawing less power.

Attention: The POE power supply is designed exclusively for use with the B08S and B16S devices. The power supply produces extensive power to support 802.3af applications. Installing the power supply in a device other than the ones documented here will cause extensive damage to your equipment.

All power supplies are auto-sensing and auto-switching.

The power supplies are installed in the slots along the bottom of the chassis.

In the B08S the 12-volt (system) power supplies occupy slot numbers 3 and 4 on the right, with the redundant supply in slot 4. The POE power supplies occupy slot numbers 1 and 2 on the left. Figure 11 on page 20 shows power supply placement.

The installed power supplies provide power to all chassis components, sharing the workload equally. If a power supply fails or overheats, the failed power supply’s workload is redistributed to the redundant power supply, if one is present.

The power supplies are hot swappable, which means you can remove and replace them without powering down the system. You can remove and insert a power supply without opening the chassis. If the device contains redundant 12-volt power supplies, you can remove one of the power supplies without interrupting operation. The remaining power supply provides enough power for all the ports. For more information about removing and installing the power supplies, see “Installing or replacing a power supply” on page 107.

CAUTION: The power supplies are hot swappable, which means they can be removed and replaced while the chassis is powered on and running. However, IBM recommends that you disconnect the power supply from the wall outlet before removing and replacing the supply. The device can be running while a power supply is being installed or removed, but the power supply itself should not be connected to a power source. Otherwise, you could be injured or the power supply or other parts of the device could be damaged.

About replacement power supplies

Replacement power supplies for the 90-240 VAC SYS and 90-240 VAC POE, are functionally equivalent to the original power supplies, and can be used in combination with the original power supplies in the same chassis. Although the model numbers for both the newer and older versions of the power supplies are identical, the front of the power supplies are visually different and the manufacturing part numbers are different.

The following illustration shows a side-by-side comparison of the 90-240 VAC SYS replacement power supply and the original power supply. The one on the left is the replacement power supply and the one on the right is the original power supply.

The latching mechanism on the front of the replacement power supplies differ from the latching mechanism on the original power supplies. The latching mechanism protrudes slightly in front, making the power supplies slightly longer in depth. For the actual dimensions, see “Physical dimensions and weight of power supplies” on page 129.

Although the model numbers 90-240 VAC SYS for the replacement and original power supplies are identical, the manufacturing part numbers are different, as noted in Table 11 on page 18. The manufacturing part numbers are inscribed on the labels affixed to the top of the power supplies. As well, the manufacturing part numbers for all installed power supplies display in the output of the show chassis command. See “Displaying chassis status and temperature readings” on page 57.

Hardware specifications for the power supplies are in Chapter 8, “Hardware specifications,” on page 121.

About redundant power supplies and power supply failure

A chassis with redundant power supplies can maintain full operation when one or more power supplies fail. Power supply failure can be a failure of the supply itself or the office power grid connected to the power supply.

A chassis can be either1+1redundant orN+1redundant. 1 + 1 redundancy implies that for every power supply, there is another redundant (backup) power supply. In other words, half of the supplies in the system can fail, and the system will still operate normally. N + 1 redundancy implies that there is one redundant power supply for N power supplies, where N is a number greater than one. for example,3+1redundancy means that in a system with four power supplies, the system will continue to operate normally if one power supply fails, but will not operate if more than one power supplies fail.

Power consumption is equally distributed (within a certain percentage depending on power load or power supply type) among all power supplies in the system. When a power supply fails, the power load is redistributed equally among the remaining power supplies. Note that power consumption between POE and System power supplies is not shared, meaning loss of a System power supply does not impact a POE power supply, and vice versa.

What happens when one or more system power supplies fail

If one or more System power supplies fail and the system is left with less than the minimum number of power supplies required for normal operation, the power supplies will go into overload and the system will start to shut down. Several things can happen. The output voltage of the remaining good power supplies will likely drop as they try unsuccessfully to generate more power than they are capable of. The system will react to a drop in voltage by increasing the current draw. The hardware will shut down due to over-current protection or under-voltage protection, whichever takes place first. One by one, the interface modules shut down until the power is within the power budget of the remaining power supplies. There is no particular order in which the interface modules will shut down, as this will occur in hardware and not in software. The management CPU requires power as well, and may also shut down during a power supply failure.

After a power loss, if the system is left with less than the minimum number of power supplies required for normal operation, the system will be left in an unknown state. At this point, manual recovery is required (restore power and power-cycle the chassis).

What happens when one or more POE power supplies fail

If one or more POE power supplies fail and the system is left with less than the minimum number of POE power supplies, the POE power supplies will go into overload. Non-POE functions will not be impacted, provided the System power supplies are still up and running. Several things can happen with a POE power supply failure. The output voltage of the remaining good power supplies will likely drop as they try unsuccessfully to generate more power than they are capable of. The system will react to a drop in voltage by increasing the current draw. The hardware will shut down POE function due to over-current protection or under-voltage protection, whichever occurs first. The interface modules will start to shut down its POE ports one by one until the over-power is within the power budget of the remaining power supplies. There is no particular order in which the POE ports will shut down, as this occurs in hardware and not in software.

Chapter 2. Product Overview 23

Cooling system

The cooling system is contained within the system’s fan tray assembly and modules. The following components comprise the cooling system:

v The B08S each has six fans. v The fans operate at four speeds. v The B16S has two five-speed fans in the rear of the chassis. v One fan control module. The fan control module maintains the power to the fans,

and controls the fan speed and the reporting of the fan status to the management module.

v Two temperature sensors on each management module, and one temperature

sensor on each interface module

v One temperature sensor on each switch fabric module (B08S and B16S only).

The fan tray in the B08S is located in the right side of each chassis. The B16S has two fan trays which are located in the top rear of the chassis.

Upon system startup, the fans operate at low speed, then adjust their speed based on the current temperature of the modules and the configured temperature thresholds, or by the manually configured fan speed.

By default, the system polls the temperature sensor on each module every 60 seconds to get a temperature reading. To read additional information about changing the default temperature polling interval, see “Changing the temperature polling interval” on page 68. Depending on the temperature readings for the modules, the system can do the following:

v Leave the fan speed at its current setting. v Increase the fan speed. v Decrease the fan speed. v If the chassis exceeds the highest temperature threshold or shutdown

temperature for five minutes, the system will shut down the device to prevent damage

If the temperature of a module exceeds specified high temperature thresholds, the system generates a Syslog message. The system can also power down the chassis if the temperature exceeds the highest threshold.

You can change default low and high temperature thresholds for modules and fan speeds. For more information, see “Changing temperature thresholds for thermal planes and fan speeds on the on the B16S” on page 62.

The chassis ships with all fan components fully installed in the fan tray. To read additional information about replacing the fan tray, see one of the following sections:

28 Ethernet Switch s-series Installation and User Guide

Power precautions and warnings

CAUTION: The power supplies are ″hot swappable″, which means they can be removed and replaced while the chassis is powered on and running. However, IBM recommends that you disconnect the power supply from the wall outlet before removing and replacing the supply. The device can be running while a power supply is being installed or removed, but the power supply itself should not be connected to a power source. Otherwise, you could be injured or the power supply or other parts of the device could be damaged.

Attention: Use a separate branch circuit for each AC power cord, which provides

redundancy in case one of the circuits fails.

Attention: The POE power supply is designed exclusively for use with the X-Series POE devices. The power supply produces extensive power to support

802.3af applications. Installing the power supply in a device other than the X-Series POE will cause extensive damage to your equipment. Use a separate branch circuit for each AC power cord, which provides redundancy in case one of the circuits fails.

Attention: Make sure the power supply is properly inserted in the slot. Never insert the power supply upside down.

Attention: Do not attempt to install the power supply without first opening the latch on the front of the power supply. Attempting to install the power supply with a closed latch will result in mechanical damage to the power supply and power supply slot.

v “Attaching a management station” on page 37 v Chapter 4, “Connecting Network Devices and Checking Connectivity,” on page 45 v “Cable specifications” on page 127.

Installation location

Before installing the device, plan its location and orientation relative to other devices and equipment. Allow at least 7.6 cm (3 in.) of space at the front of the device for the fiber-optic and power cabling. Also, allow a minimum of 7.6 cm (3 in.) of space between the sides and the back of the device and walls or other obstructions.

Removing extra shipment screws (B08S only)

The B08S ship with two extra screws installed in the right side of the chassis. These screws secure the fan tray, protecting it from damage during shipment. You must remove these screws before installing the chassis. Figure 16 on page 30 shows the location of the screws.

To perform this task, you need a #2 Phillips-head screwdriver.

Installing a chassis in a rack

Because of the weight of a fully loaded chassis (97 lbs minimum), IBM recommends mounting a chassis in a rack before installing the modules and power supplies.

You can flush mount the B08S using the built-in mounting brackets on the front of the device. Alternatively, you can use the optional rack mount kit to mid-mount the chassis in a rack. The B16S does not have adjustable mounting brackets. To mount the B16S in a rack, you will need to install the brackets in the rack mount kit that ships with the chassis, as shown in Figure 19 on page 32.

Chassis rear

net08bs027

Before performing this task, you should have an assembled rack and a #2 Phillips-head screwdriver.

See “Rack safety” on page xx for precautions when installing equipment in a rack.

Each device that you install in a rack, you must provide four mounting screws with which to secure the chassis.

To mount the chassis in a rack using the adjustable mounting brackets, do the following:

1. Determine the position of each chassis in the rack.

2. Position two of the four mounting screws for each chassis that you plan to mount in the rack according to the spacings of the keyhole slots on the brackets as shown in Figure 17 on page 31. Do not secure the screws completely; leave approximately 1/4 inch of clearance between the back of the screw head and the rack.

Figure 17. Positioning two of four mounting screws in a rack.

3. Mount the chassis that goes in the lowest position in the rack, as shown in Figure 18. With two or more people lifting the chassis, slip the wide portion of each keyhole slot over the corresponding screw in the rack.

net08bs029

Figure 18. Front-mount-rack-installation into chassis

4. Slide the chassis down so that the screw heads are in the narrow portion of the keyhole slots.

5. Install the remaining two mounting screws through the opposite corners of the brackets into the rack.

6. Tighten all screws to secure the chassis in place.

7. Repeat the steps to mount each subsequent chassis in the same rack.

Chapter 3. Installing the Chassis 31

Installing mounting brackets on the B16S

The B16S does not ship with mounting brackets installed. You will need to install the brackets yourself, using a #2 Phillips or flathead screwdriver. Mount the brackets as shown in Figure 19. Since the brackets are identical, you must flip one bracket 180 degrees to fit on the opposite side from the first bracket.

Empty chassis with slot panels in place

Figure 19. Installing the mounting brackets on an B16S

Consult “Installing a chassis in a rack” on page 30 for instructions on how to install the B16S in the rack.

Removing the slot panels

The chassis ships with a slot panel installed that covers each empty module slot, ensuring proper airflow within the chassis. If you plan to install a module in a particular slot, you must first remove the slot panel.

Attention: If you do not install a module in a slot, you must keep the slot panel in place. If you operate the chassis with an uncovered slot, the system will overheat.

Although the slot panels may differ in size, the procedure for removing them from the chassis is the same. The procedure in this section applies to all module slot panels.

You need a #2 Phillips-head or flathead screwdriver to perform this task.

To remove a slot panel, do the following:

1. Loosen the screws on either end of the slot panel with a #2 Phillips-head or flathead screwdriver.

2. Pull the slot panel out of the chassis, and store it in a safe place for future use.

Installing the management and interface modules

This section provides the procedures for installing the management and interface modules. Although the modules may differ in size and function, the procedure for installing each of them into the chassis is the same. The procedure described in this section applies to all devices.

The B08S and B16S management modules are hot swappable, which means you can remove and insert them while the chassis is powered on and running.

Notes:

1. The interface modules are interchangeable among the s-series products. However, if you try to install them in chassis other than those documented here, the chassis and interface modules will not function properly.

2. You cannot mix IPv4 and IPv6 modules together in the same chassis. A chassis must either contain all IPv4 management modules and IPv4 interface modules or all IPv6 management modules and IPv6 interface modules.

Table 14 provides the chassis slot numbers into which you must install the modules. The following figures show the chassis with slot numbers:

v B08S - Figure 2 on page 7. v B16S - Figure 4 on page 9.

Table 14. Module Installation

Module B08S Slot Number B16S Slot Number

Management module 9 and 10 9 and 10 Interface modules 1 - 8 1-8and11-18

Attention: If you do not install a module in a slot, you must leave the slot panel installed in the slot. If you operate the chassis with an uncovered empty slot, the system will overheat.

Before installing a module in the chassis, have the following on hand: v An ESD wrist strap with a plug for connection to the ESD connector on the

chassis.

CAUTION: For safety reasons, the ESD wrist strap should contain a series 1 meg ohm resistor.

v A #2 Phillips-head or flathead screwdriver.

To install a module in the chassis, do the following:

1. Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector located on the chassis front.

2. Remove the module from its packaging.

3. Insert the management module or the interface module into the appropriate chassis slot and slide the card along the card guide until the ejectors on either side of the module move close to the module front panel.

4. Push the ejectors toward the center of the module to fully seat the module in the backplane.

5. Use the #2 Phillips-head or flathead screwdriver to tighten the two screws at either end of the module front panel.

Attaching a management station

You can manage the device in the following ways: v You can connect a PC or terminal to the management module’s serial (console)

port or 10/100/1000 Ethernet port and access the system directly from the PC or terminal, or from a Telnet connection to the PC or terminal. For more information, see “Attaching a PC or terminal to the console port or 10/100/1000 copper port.”

v You can connect the switch to your existing management network and manage

the switch, along with other network devices, from a management station. To do this, you can connect a switch to a Gigabit Ethernet port on the management module. For more information, see “Attaching a switch to an Ethernet port” on page 38.

Note: The management network into which you can connect a Gigabit Ethernet

port must be separate and isolated from the network over which user packets are switched and routed.

Attaching a PC or terminal to the console port or 10/100/1000 copper port

The management module’s console port, which has a male DB-9 serial connector, and 10/100/1000 Ethernet copper port(s), which have RJ-45 UTP connectors, allow you to attach a PC or terminal. From the console port, you can access the system’s CLI directly from the PC or terminal or via a Telnet connection to the PC or terminal. From the Ethernet port, you can access the system’s CLI or Web management interface directly from the PC or terminal or via a Telnet connection to the PC or terminal.

Before performing this task, you need the following items:

v PC running a terminal emulation application or a terminal v If connecting the PC or terminal to the console port, a straight-through EIA/TIA

DB-9 serial cable with one end terminated in a female DB-9 connector and the other end terminated in a male or female DB-9 or DB-25 connector, depending on the specifications of your PC or terminal. You can order the serial cable separately from IBM or build your own cable. If you prefer to build your own, see the pinout information in “Serial (console) port pinouts” on page 125.

v If connecting the PC or terminal to a Gigabit Ethernet copper port, a category 5

UTP crossover cable, which you must supply. To read additional information about the port pin assignments, see “10/100 and Gigabit port pinouts” on page

126.

To attach a PC or terminal to the console port or Gigabit Ethernet copper port, do the following:

1. Connect a PC or terminal to the console port or a 10/100/1000 Ethernet port using the appropriate cable.

2. Open the terminal emulation program, and set the session parameters as follows:

v Baud: 9600 bps v Data bits: 8 v Parity: None v Stop bits: 1

Chapter 3. Installing the Chassis 37

v Flow control: None

Attaching a switch to an Ethernet port

The B08S and B16S management module’s 10/100/1000 Ethernet copper port enable you to attach a networking switch. A management station in your existing management network can then access the switch using the IronView Network Manager.

For more information, see Chapter 4, “Connecting Network Devices and Checking Connectivity,” on page 45.

Powering on the system

After you complete the hardware installation, you can power on the system. Verify that all modules and power supplies are fully and properly installed and no module slots are uncovered.

Note the following before powering on the system:

Attention: If you do not install a module in a slot, you must keep the slot panel in place. If you run the chassis with an uncovered slot, the system will overheat.

Note: The wall outlet should be installed near the equipment and should be easily

accessible.

Note: The switch is designed to provide uninterrupted service even when you

insert or remove the interface modules. Therefore, the system does not have a separate on/off power switch. To turn the system off, unplug the power cord(s).

Connecting AC power to the chassis

AC power is supplied though an AC power cord that is installed at the rear of the chassis.

1. At the rear of the chassis, locate the power receptacle where the power supplies have been installed.

2. Lift the cord-retainer and connect the AC power cord to the power supply.

3. Snap the cord-retainer over the power plug to hold it in place, as illustrated below.

Step Task Topic for reference

1 Secure access to the CLI by assigning passwords. “Assigning permanent passwords” 2 Configure IP addresses for the management,

Ethernet, virtual, and loopback interfaces. 3 Connect your device to another networking device. “Connecting network devices” on page 50 4 Test a port for connectivity to other networking

devices using the ping and traceroute commands. 5 Troubleshoot any problems that can arise. “Troubleshooting network connections” on

Assigning permanent passwords

By default, the CLI is not protected by passwords. To secure CLI access, IBM strongly recommends assigning passwords.

“Configuring IP addresses” on page 46

“Testing network connectivity” on page 54

page 56

Note: You cannot assign a password using the Web management interface. You

can assign passwords using IronView Network Manager if an enable password for a Super User has been configured on the device.

The CLI contains the following access levels: v User EXEC - The level you enter when you first start a CLI session. At this level,

you can view some system information but you cannot configure system or port parameters.

v Privileged EXEC - This level is also called the Enable level and can be secured

by a password. You can perform tasks such as manage files on the flash module, save the system configuration to flash, and clear caches at this level.

v CONFIG - The configuration level. This level lets you configure the system’s IP

address and configure switching and routing features. To access the CONFIG mode, you must already be logged into the Privileged level of the EXEC mode.

You can set the following levels of Enable passwords: v Super User - Allows complete read-and-write access to the system. This is

generally for system administrators and is the only password level that allows you to configure passwords.

Note: You must set a Super User password before you can set other types of

passwords.

v Port Configuration - Allows read-and-write access for specific ports but not for

global (system-wide) parameters.

v Read Only - Allows access to the Privileged EXEC mode and CONFIG mode but

only with read access.

To set passwords:

1. At the opening CLI prompt, enter the following command to change to the Privileged level of the EXEC mode:

FastIron> enable

2. Access the CONFIG level of the CLI by entering the following command:

FastIron# configure terminal (config)#

3. Enter the following command to set the super-user password:

FastIron(config)# enable super-user-password <text>

4. Enter the following commands to set the port configuration and read-only passwords:

FastIron(config)# enable port-config-password <text> FastIron(config)# enable read-only-password <text>

Syntax: enable super-user-password | read-only-password | port-config-password <text>

Passwords can be up to 32 characters long.

Configuring IP addresses

You must configure at least one IP address using the serial connection to the CLI before you can manage the system using the other management interfaces. In addition, IBM Ethernet routers require an IP subnet address for the subnet in which you plan to place them in your network.

IPv4 devices

IPv4 devices support both classical IP network masks (Class A, B, and C subnet masks, and so on) and Classless Inter-domain Routing (CIDR) network prefix masks.

v To enter a classical network mask, enter the mask in IP address format. For

example, enter: 209.157.22.99 255.255.255.0 for an IP address with a Class-C subnet mask.

v To enter a prefix number for a network mask, enter a forward slash(/)andthe

number of bits in the mask immediately after the IP address. for example, enter “209.157.22.99/24” for an IP address that has a network mask with 24 significant (“mask”) bits.

By default, the CLI displays network masks in classical IP address format (example:

255.255.255.0). You can change the display to the prefix format. See the

Configuration Guide For more information.

IPv4 devices running layer 3 software

Before attaching equipment to a router, you must assign an interface IP address to the subnet on which the router will be located. You must use the serial connection to assign the first IP address. for subsequent addresses, you also can use the CLI through Telnet or the Web management interface.

By default, you can configure up to 24 IP interfaces on each port, virtual interface, and loopback interface. You can increase this amount to up to 64 IP subnet addresses per port by increasing the size of the subnet-per-interface table. See the Configuration Guide For more information.

46 Ethernet Switch s-series Installation and User Guide

The following procedure shows how to add an IPv4 address and mask to a router port.

1. At the opening CLI prompt, enter enable.

FastIron> enable

2. Enter the following command at the CLI Privileged EXEC level prompt, then press Enter. This command erases the factory test configuration if still present:

FastIron# erase startup-config

Attention: Use the erase startup-config command only for new systems. If you enter this command on a system you have already configured, the command erases the configuration. If you accidentally do erase the configuration on a configured system, enter the write memory command to save the running configuration to the startup-config file.

3. Access the configuration level of the CLI by entering the following command: Privileged EXEC Level:

FastIron# configure terminal

Global CONFIG Level:

FastIron(config)#

4. Configure the IPv4 address and mask address for the interface:

FastIron(config)# int e 1/5 FastIron(config-if-e1000-1/5)# ip address 192.22.3.44 255.255.255.0

Note: You can use the syntax ip address <ip-addr>/<mask-bits> if you know

the subnet mask length. In the above example, you could enter ip

address 192.22.3.44/24. Syntax: enable [<password>] Syntax: configure terminal Syntax: [no] ip address <ip-addr> <ip-mask> [secondary] or Syntax: [no] ip address <ip-addr>/<mask-bits> [secondary] Use the secondary parameter if you have already configured an IP address

Connecting network devices

These devices support connections to other vendors’ routers, switches, and hubs, as well other IBM devices.

Cable specifications

See “Cable specifications” on page 127 for cable lengths and types.

Connecting to Ethernet or fast Ethernet hubs

For copper connections to Ethernet hubs, a 10/100Base-TX or 1000Base-T switch, or another IBM device, a crossover cable is required. If the hub is equipped with an uplink port, it will require a straight-through cable instead of a crossover cable.

Note: The 802.3ab standard (automatic MDI/MDIX detection) calls for automatic

negotiation of the connection between two 1000Base-T ports. Therefore, a crossover cable may not be required; a straight-through cable may work as well. For more information about this feature, see the Configuration Guide.

Note: The 802.3ab standard calls for automatic negotiation of the connection

between two 1000Base-T ports. Consequently, a crossover cable may not be required; a straight-through cable may work as well.

Connecting to workstations, servers, or routers

Straight-through UTP cabling is required for direct UTP attachment to workstations, servers, or routers using network interface cards (NICs).

Fiber cabling with LC connectors is required for direct attachment to Gigabit NICs or switches and routers.

Connecting a network device to a fiber port on the device

For direct attachment from the device to a Gigabit NIC, switch, or router, fiber cabling with an LC connector is required.

Note: All physical IP interfaces on the Layer 3 devices share the same MAC

address. For this reason, if more than one connection is made between two devices, one of which is an s-series Layer 3 device, IBM recommends the use of virtual interfaces. It is not recommended to connect two or more physical IP interfaces between two routers.

To connect a device to another network device using a fiber port, you must do the following:

1. Install a fiber optic module (SFP transceiver for Gigabit Ethernet ports, or XFP-MSA transceiver for 10-Gigabit Ethernet ports)

2. Cable the fiber optic module

The following sections provide information about performing these tasks.

Installing a fiber optic module

You must install a fiber optic module in each Gigabit Ethernet and 10-Gigabit Ethernet fiber port you want to use.

Attention: Before beginning any of these procedures, read the “Safety notices” on page xiii.

Before installing a fiber optic module, have the following on hand: v An ESD wrist strap with a plug for connection to the ESD connector on the

chassis.

CAUTION: for safety reasons, the ESD wrist strap should contain a series 1 meg ohm resistor.

To install a fiber optic module into a Gigabit Ethernet or 10-Gigabit Ethernet port, do the following:

1. Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector located in the lower right corner of the chassis front.

2. Remove the module from its protective packaging.

3. If necessary, remove the metal cover from the port on the interface module’s control panel.

4. Gently insert the fiber-optic module into the port until the module clicks into place. The fiber-optic modules are keyed to prevent incorrect insertion.

Cabling a fiber optic module

To cable a fiber-optic module, do the following:

1. Remove the protective covering from the fiber optic module and store the covering for future use.

2. Before cabling a fiber optic module, IBM strongly recommends cleaning the cable connectors and the port connectors. For more information, see “Cleaning fiber optic modules” on page 53.

52 Ethernet Switch s-series Installation and User Guide

3. Gently insert the cable connector(s) (a tab on each connector should face upward) into the port connector(s) until the tabs lock into place.

Cleaning fiber optic modules

To avoid problems with the connection between the fiber optic module (SFP or XFP) and the fiber cable connectors, IBM strongly recommends cleaning both connectors each time you disconnect and reconnect them. See “Cleaning the fiber optic connectors” on page 91.

Automatic MDI/MDIX detection

All 10/100 and Gigabit Ethernet Copper ports on the devices support automatic Media Dependent Interface (MDI) and Media Dependent Interface Crossover (MDIX) detection. This feature is enabled on all 10/100 and Gigabit copper ports by default. For each port, you can disable auto MDI/MDIX, designate the port as an MDI port, or designate the port as an MDIX port.

For more information about this feature and how configure it, see the Configuration Guide.

Using a CX4 transceiver

A twin-axial 10G copper CX4 XFP transceiver can be installed in any 10G port. for a link to operate properly, both sides must use identical CX4 transceivers.

The CX4 transceiver requires a 15 meter CX4-grade cable with 24 or 26 American Wire Gauge (AWG).

Note: The CX4 transceiver is not hot-swappable.

Testing network connectivity

After you install the network cables, you can test network connectivity to other devices by pinging those devices. You also can observe the LEDs related to network connection and perform trace routes.

Pinging an IP address

To verify that you can reach another device through the network, enter the ping command at any level of the CLI on the device:

FastIron> ping 192.33.4.7

Syntax: ping

<ip addr> | <hostname> [source <ip addr>] [count <num>] [timeout <msec>] [ttl <num>] [size <byte>] [quiet] [numeric] [no-fragment] [verify] [data <1-to-4 byte hex>] [brief]

See the Configuration Guide to read additional information about the parameters.

net48bg030

Note: If you address the ping to the IP broadcast address, the device lists the first

four responses to the ping.

Observing LEDs

After you install the network cables, you can observe certain LEDs to determine if the network connections are functioning properly. Table 17 on page 55 outlines the LEDs related to the network connections, the desired state of each LED, possible abnormal states of each LED, and what to do if an LED indicates an abnormal state.

Note: Some modules use combined link and activity LEDs.

54 Ethernet Switch s-series Installation and User Guide

Table 17. Network Connection-Related LED States

LED Desired State Meaning Abnormal State Meaning/Action

Link On (Green) A link is established with

the remote port.

Active On or blinking

(Yellow)

The port is transmitting and receiving user packets.

Off A link is not established with the

remote port. You can do the following: v Verify that the connection to the

other network device has been properly made. Also, make certain that the other network device is powered on and operating correctly.

v Verify that the transmit port on the

device is connected to the receive port on the other network device, and that the receive port on the device is connected to the transmit port on the other network device. If you are not certain, remove the two cable connectors from the port connector and reinsert them in the port connector, reversing their order.

v Dust may have accumulated in the

cable connector or port connector. To read additional information about cleaning the connectors, see “Cleaning fiber optic modules” on page 53.

v If the other actions don’t resolve the

problem, try using a different port or a different cable.

Off for an extended period.

The port is not transmitting or receiving user packets. You can do the following:

v Check the Link LED to make sure

the link is still established with the remote port. If not, take the actions described in the Meaning/Action column for the Link LED.

v Verify that the port has not been

disabled through a configuration change. You can use the CLI. If you have configured an IP address on the device, you also can use the Web management interface or IronView Network Manager.

Tracing a route

If a problem persists after taking these actions, contact IBM Support.

To determine the path through which a device can reach another device, enter a command such as the following at any level of the CLI on the device:

FastIron> traceroute 192.33.4.7

Syntax: traceroute traceroute <host-ip-addr> [maxttl <value>] [minttl <value>] [numeric] [timeout <value>] [source-ip <ip addr>]

Chapter 4. Connecting Network Devices and Checking Connectivity 55

The CLI displays trace route information for each hop as soon as the information is received. Traceroute requests display all responses to a given TTL. In addition, if there are multiple equal-cost routes to the destination, the device displays up to three responses by default.

See the Command Line Interface Reference to read additional information about the command syntax.

Troubleshooting network connections

To resolve problems that may arise with network connections: v For the indicated port, verify that both ends of the cabling (at the device and the

connected device) are snug.

v Verify that the IBM device and the connected device are both powered on and

operating correctly.

v Verify that the port has not been disabled through a configuration change. You

can use the CLI. If you have configured an IP address on the device, you also can use the Web management interface or IronView Network Manager.

v Verify that you have used the correct cable type for the connection:

– for twisted-pair connections to an end node, use straight-through cabling. – for fiber-optic connections, verify that the transmit port on the device is

connected to the receive port on the connected device, and that the receive port on device is connected to the transmit port on the connected device.

v For copper ports, you can test the cable using Virtual Cable Testing. For more

information, see the chapter, ″Monitoring Hardware Components″ in the Configuration Guide.

v If the other procedures don’t resolve the problem, try using a different port or a

different cable.

Digital optical monitoring

You can configure your device to monitor optical transceivers in the system, either globally or by specified port(s). When this feature is enabled, the system will monitor the temperature and signal power levels for the optical transceivers in the specified port(s). Console messages and syslog messages are sent when optical operating conditions fall below or rise above the XFP or SFP manufacturer’s recommended thresholds. For details about this feature and how to configure it, see the Configuration Guide.
