Safety Information

Class 1 Laser Transceivers

The single mode interface modules use Class 1 laser transceivers.

Read the following safety information before installing or operating these modules.

The Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This control loop eliminates the need for maintenance checks or adjustments. The output is factory set, and does not allow any user adjustment. Class 1 Laser transceivers comply with the following safety standards:

• 21 CFR 1040.10 and 1040.11 U.S. Department of Health and Human Services (FDA).

• IEC Publication 825 (International Electrotechnical Commission).

• CENELEC EN 60825 (European Committee for Electrotechnical Standardization).

When operating within their performance limitations, laser transceiver output meets the Class 1 accessible emission limit of all three standards. Class 1 levels of laser radiation are not considered hazardous.

When the connector is in place, all laser radiation remains within the fiber. The maximum amount of radiant power exiting the fiber (under normal conditions) is -12.6 dBm or 55 x 10

Removing the optical connector from the transceiver allows laser radiation to emit directly from the optical port. The maximum radiance from the optical port (under worst case conditions) is 0.8 W cm

Do not use optical instruments to view the laser output. The use of optical instruments to view laser output increases eye hazard. When viewing the output optical port, power must be removed from the network adapter.

-6

watts.

-2

or 8 x 103 W m2 sr-1.

Safety Compliance

Warning: Fiber Optic Port Safety

When using a fiber optic media expansion module, never look at the transmit laser while it is powered on. Also, never look directly at the fiber TX port and fiber cable ends when they are powered on.

Avertissment: Ports pour fibres optiques - sécurité sur le plan optique

Ne regardez jamais le laser tant qu’il est sous tension. Ne regardez jamais directement le port TX (Tramsmission) à fibres optiques et les embouts de câbles à fibres optiques tant qu’ils sont sous tension.

Warnhinweis: Faseroptikanschlüsse - Optische Sicherheit

Niemals ein Übertragungslaser betrachten, während dieses eingeschaltet ist. Niemals direkt auf den Faser-TX-Anschluß und auf die Faserkabelenden schauen, während diese eingeschaltet sind.

AC Power Supplies

Two 800 watt (PoE) and two 460 watt AC power supply models, which you must order separately, are available for the 7100G-Series switch depending upon the model:

71G21K2L2-48P and 71G21K2L2-24P24:

• 71A-POE-A – I/O port side air exhaust

• 71A-POE-B – I/O port side air intake

71G11K2L2-48:

• 71A-PS-A – I/O port side air exhaust

• 71A-PS-B – I/O port side air intake

Each power supply option contains a single non-reversible fan. The two power supply options for each 7100-Series model are differentiated by the direction of the power supply fan air flow. Power supply air flow must agree with the air flow direction of the installed fan modules.

The 7100G-Series AC power supplies automatically adjust to the input voltage and frequency, which allows for an input voltage of 100 to 240 Vac, and a frequency between 50 and 60 Hz. See the operating specifications in Appendix A, Specifications. No additional adjustments are necessary. For installations in North America, a 15 Amp power cord is required. See “Powering Up the

7100G-Series Switch” on page 2-14 for more details.

AC Power Supplies

You can install up to two power supplies in the 7100G-Series chassis. All the power supply needs of the 7100G-Series switch can be met by installing a single power supply. If you choose to use two power supplies, system power redundancy is guaranteed if one supply is lost. Power supplies are hot swappable in redundant power supply mode.

For more information, see “Installing the Power Supplies” on page 2-12. For information on the power supply LED, see “Power Supply LED” on page 3-5.

Fans

The 7100G-Series switch comes with a single installed fan module to cool the system. The direction of the fan module air flow is reversible. By default air flows from the power supply side to the switch I/O port side of the unit. If your 7100G-Series switch configuration requires switch I/ O port side to power supply side air flow, see “Reversing the Fan Module Air Flow” on page 2-5 for details about how to reverse the fan module air flow.

The 7100G-Series fan module is field replaceable. For information on how to replace 7100G-Series fan module, see “Replacing the 7100G-Series Fan Module” on page 3-8.

Micro-USB Port

The micro-USB port is provided for local file transfer.

Management

You can manage the 7100G-Series switch either in-band or out-of-band. In-band remote management is possible using the Enterasys Networks’ NetSight command line interface (CLI) via Telnet. Out-of-band management is provided through the RJ45 COM (Communication) port on the front panel using a PC, a VT terminal, or a VT terminal emulator. For more information, see “Connecting to the Network” on page 2-15.

management application or the

Enterasys 7100G-Series Hardware Installation Guide 1-3

Virtual Switch Bonding

For data center redundancy, you can configure two co-located 7100G-Series chassis to operate as a single logical chassis (a virtual switch bonded chassis) managed by one IP address. Connect the chassis to each other by using the two 40Gb ports on each 7100G-Series chassis.

Note: For virtual switch bonding configuration details, see the Enterasys 7100-Series Configuration Guide.

2-2 Installation

If there are any signs of damage, DO NOT install the 7100G-Series switch; instead, contact Enterasys Networks. Refer to “Getting Help” on page xvii for details.

Mounting the 7100G-Series Switch

Note: The 7100G-Series switch comes with integrated mounting ears that are adequate for most

installations. For slide-in mounting, high vibration, or high shock installations, an optional rack mount kit (71A-RACK-U) is available.

To install the 7100G-Series switch in a rack using the 71A-RACK-U optional rack mount kit, follow the pre-installation discussion here including: “Power Supply Air Flow and Switch Fan Module

Air Flow” on page 2-4 and “Reversing the Fan Module Air Flow” on page 2-5, before proceeding

to “Optional Rack Mount Rail Kit Installation” on page C-1.

You can install a 7100G-Series switch on a flat surface or in a rack. For more information about flat surface installation, see “Flat Surface Installation” on page 2-12.

There are four possible rack mounting configurations as shown in Figure 2-1, based upon whether:

• The switch I/O ports side or the power supply side of the device face front

• The device is mounted flush with the rack posts or mid-mounted

Mounting the 7100G-Series Switch

Power Supply Air Flow and Switch Fan Module Air Flow

The power supply module has its own fan for cooling the power supply, and the switch fan module has four fans for cooling the switch circuitry. The air flow direction of both the power supply and fan modules must agree in order to properly cool the installed 7100G-Series system. In rack mount configurations it is best practice to mount all devices with a common cool air side and a common exhaust (hot air) side.

On the 7100-Series switch, air flow direction can be from either:

• The power supply side to the switch I/O port side

• The switch I/O port side to the power supply side

Note: The power suppl(ies) must be ordered separately from the switch unit, and air flow direction must be specified when ordering them. Power supply air flow direction is fixed and can not be manually changed. If the ordered power supply has an air flow direction that does not work for your rack configuration, you must re-order the power supply that has the correct air flow direction (see

Table 2-3).

The 7100-Series switch is shipped from the factory set up for air flow direction from the power supply side to the switch I/O port side of the device. If your installation requires that air flow direction be from the I/O port side to the power supply side, you will need to reverse the air flow of the switch fan module fans (see “Reversing the Fan Module Air Flow” on page 2-5). Also, the rack mount flanges (ears) need to be reversed (see “Rack Mount Ear Positioning” on page 2-7).

Air flow direction of the switch fan modules can be determined by visually inspecting them for whether a white label or a fan blade is visible through the fan screen. Before securing the 7100G-Series switch to the rack or installing the power supply into the 7100G-Series switch, perform a visual verification that both power supply module and switch fan module air flow agree with the intended configuration as defined in Tab le 2 -2 and Tabl e 2 -3.

Unpack each power supply you ordered for the 7100G-Series switch (See “Unpacking the Power

Supplies” on page 2-12).

Table 2-2 Switch Fan Module Air Flow Direction

Air Flow Direction Visual Indication

From power supply side to switch I/O port side Fan blade is visible on fan unit From switch I/O port side to power supply side White label is visible on fan unit

For the non-PoE power supplies, the power supply air flow direction can also be verified based upon the power supply manufacturer’s part number located on the power supply bottom label and the airflow direction indicator on the serial number label located on the lower right edge of the regulatory label. The PoE power supplies are labeled with the model number and an air flow arrow indicating unit air flow direction on the power supply bottom label.

Reversing the Fan Module Air Flow

Note: If the 7100-Series switch rack configuration requires the air flow to be from the switch I/O port

side to the power supply side, the air flow in the switch fan modules must be reversed for the switch fan module.

Removing the Fan Module

To remove the switch fan module:

1. Unscrew the two fan module captive screws as shown in Figure 2-2 on page 2-5.

2. Slide the fan module forward until it is unplugged from the device.

Reversing the Fan Unit

The switch fan module has a single reversible dual fan unit. When the fan unit is properly seated, the air flow indicator arrow is completely visible as shown in callout 1, Figure 2-3 on page 2-6. The air flow indicator arrow points in the direction the fan unit flows air through the fan module.

In the power supply module to switch I/O port (default) air flow configuration, a metal plate covers the fan unit (as shown in Figure 2-2, callout 4, above). When the fan unit is reversed, the fan unit is visible (as shown in callout 3, Figure 2-3). To reverse the fan module air flow:

1. Hold the module in your hand

2. Apply pressure to the inner edge of the fan unit to rotate the fan unit (thick black arrows in

Figure 2-3).

3. Flip the fan unit 180 degrees until the air flow indicator is again completely visible and pointing towards the fan module screen, as shown in callout 4, Figure 2-3.

1. Align the fan module with the fan module opening.

2. Insert the module into the fan module opening, applying enough pressure that the fan module is flush with the device.

3. Secure the two fan module captive screws.

Rack Mount Ear Positioning

If you are installing the 7100G-Series switch using the 71A-RACK-U optional rack mount kit, proceed to “Optional Rack Mount Rail Kit Installation” on page C-1.

When shipped from the factory, the 7100G-Series switch has rack mount ears attached to the edge of the side of the switch containing the power supply in a flush mount configuration, as shown in callout 2 of Figure 2-1 on page 2-3. If you are mounting the switch using the factory positioning of the rack mount ears, go to “Securing the 7100G-Series Switch to the Rack” on page 2-10.

The rack mount ears can be repositioned providing three alternative mounting options.

Alternative mounting options are described in the following sections:

•“Flush-Mount Switch I/O Ports Facing Front Configuration” on page 2-7

Replacing the 7100G-Series Fan Module

The 7100G-Series switch is cooled by a fan module accessible from the power supply side of the unit. If the FAN LED and the output of the CLI show system command indicate that the fan module has failed, you must replace the failed fan module.

Note: The 7100G-Series fan module is hot-swappable. Do not uninstall a failed fan module until its replacement is available. All 7100G-Series switch components and cover plates must be installed to ensure proper air flow.

The replacement fan kit, 71A-71GFAN, which you must order separately, contains one replacement fan.

To replace the failed fan module:

1. Unscrew the two captive screws of the failed fan module as shown in Figure 3-4 on page 3-8.

2. Following the discussion in “Power Supply Air Flow and Switch Fan Module Air Flow” on page 2-4, ensure that the new fan module air flow direction agrees with the installed 7100GSeries switch configuration.

3. If a non-default air flow is required, see “Reversing the Fan Module Air Flow” on page 2-5 for directions on how to reverse the fan unit direction.

4. Once you have ensured that the fan module air flow is appropriate to your system configuration, slide the currently installed fan module forward until it is unplugged from the device as shown in Figure 3-4.

Figure 3-4 Removing the Fan Module

3-8 Troubleshooting

1 Fan Module Screws

5. Align the new fan module with the fan module opening.

6. Insert the module into the fan module opening, applying enough pressure that the fan module is flush with the device.

7. Secure the two fan module captive screws.

Removing a Power Supply

To remove a power supply from the 7100G-Series switch:

1. Use appropriate antistatic protection when handling power supplies.

2. If a power cord retention clip is securing the power cord, push down on the retention clip clamp tab to open the clamp and disengage the power cord from the clamp.

3. Unplug the associated power cord from the AC inlet.

4. Do not remove the power supply in power supply bay PS1 until a replacement power supply is available.

5. Remove the power supply by simultaneously pressing the power supply lock tab in the direction specified for your unit in Figure 3-5, grasping the handle, and pulling the power supply straight out of the 7100G-Series switch.

6. If you are removing the power supply from power supply bay PS2, and you are not immediately installing another power supply, reinstall the coverplate that comes with the 7100G-Series switch over the empty PS2 power supply bay.

Removing a Power Supply

Caution: If you plan to operate the chassis with only one power supply, the power supply must be installed in the left power slot labeled PS1 and the coverplate must be in place in the right power slot to contain EMI radiation and ensure proper air circulation.

Precaución: Si desea trabajar sólo con una fuente de poder, no olvide colocar la tapa en el compartimiento de la fuente de poder que haya eliminado, para reducir la interferencia electromagnética y para asegurar una buena ventilación.

Recommended Shutdown Procedure Using OFFLINE/RESET Button

Before shutting off power to a 7100G-Series switch, press or tap on its OFFLINE/RESET button for less than one second.

The 7100G-Series system CPU LED changes from solid green to blinking between green and amber, indicating that the 7100G-Series switch is shutting down. At the end of the shutdown routine, the CPU LED changes to a 67%/33% sequence of amber/off, respectively, indicating the system is in a halt state. At this time it is safe to restart the 7100G-Series switch.

When you initiate a controlled shutdown with the OFFLINE/RESET button, you have 60 seconds from the time the CPU LED starts flashing amber/off until the device automatically restarts.

3-10 Troubleshooting

Using the OFFLINE/RESET Button

Last Resort Shutdown Procedure Using OFFLINE/RESET Button

Caution: This method of shutting down a 7100G-Series switch is not recommended except as a

last resort, because all processes currently running on the 7100G-Series switch will be interrupted resulting in loss of frames.

Precaución: No se recomienda utilizar este método para apagar los módulos 7100G-Series. Recurra a él sólo como último recurso, puesto que interrumpe todos los procesos del módulo en funcionamiento, lo que podría resultar pérdidas de frames.

To reset an 7100G-Series switch without it performing an orderly shutdown routine, press and hold the OFFLINE/RESET button for approximately 6 seconds.

When troubleshooting the 7100G-Series switch it may become necessary to clear the persistent storage in NVRAM or the system password. There are two methods available:

• Enter boot loader mode during the bootup process

• Manually setting a dip switch internal to the device

This appendix details the two methods available for clearing persistent storage or system password on the 7100G-Series switch.

Clearing Persistent Storage or Password using the Boot Loader Method

Persistent storage can be cleared or the system password reset to factory default using the boot loader by connecting a terminal application to the serial (console) port. Serial console access to the boot loader has been successfully tested with the following applications:

–HyperTerminal

– TeraTerm

Any other terminal applications may work but are not explicitly supported.

To either clear the 7100G-Series switch persistent storage or only the system password, proceed as follows:

1. With the console port connected, power up the device. The following message displays:

Boot ROM Initialization, Version 01.00.02

Testing SDRAM.... PASSED.

Loading Boot Image: 0x.00.yy... DONE. Uncompressing Boot Image... DONE.

2. Once the boot image is finished uncompressing, you receive a message indicating you have 3 seconds to access the bootloader menu by pressing any key. Press a key and the system image loader prompt displays:

###You have 3 seconds to access the bootloader menu### Press any key to enter System Image Loader menu

Switch definitions and positions are as follows:

• Switches 1– 6: For Enterasys Networks use only.

• Switch 7: Clear Persistent Data. Changing the position of this switch from the up position to the down position clears persistent data on the next power-up of the 7100G-Series switch. All user-entered parameters, such as the IP address, system name, and so on, are reset to the factory default settings. Once the system resets, you can either use the factory default settings or reenter your own parameters.

• Switch 8: Clear Admin Password. Changing the position of this switch from the up position to the down position clears the admin password, and restores the factory default password on the next power-up of the system. Once the 7100G-Series switch resets, you can either use the factory default setting or reenter your own password.

Note: Do not change the position of Switch 8 unless it is necessary to reset the admin password to its factory default setting.

Installation Site Requirements

If you plan to cable your 7100G-Series chassis with SFP+ pluggable transceivers, you may need to have 3–4 inches of clearance on the switch I/O port side of the 7100G-Series chassis.

See Appendix E, Environmental Guidelines for environmental guidelines relating to the 7100GSeries switch installation.

The installation site must be within reach of the network cabling and meet the requirements listed below:

• Appropriate grounded power receptacles must be located within 7 feet of the site.

• A temperature of between 5°C (41°F) and 40°C (104°F) must be maintained at the installation site with fluctuations of less than 10°C (18°F) per hour.

Caution: To ensure proper ventilation and prevent overheating, leave a minimum clearance space of 5.1 cm (2.0 in.) at the front and rear of the device.

Precaución: Para asegurar una buena ventilación y evitar que el sistema se sobrecaliente, deje un espacio mínimo de 5.1 cm (2 pulgadas) con respecto el anverso y reverso del aparato.

Warning: Before rack-mounting the device, ensure that the rack can support it without compromising stability. Otherwise, personal injury and/or equipment damage may result.

Advertencia. Antes de montar el equipo en el rack, asegurarse que el rack puede soportar su peso sin comprometer su propia estabilidad, de otra forma, daño personal o del equipo puede ocurrir.

Warnhinweis: Überzeugen Sie sich vor dem Einbau des Gerätes in das Rack von dessen Stabilität, ansonsten könnten Personenschäden oder Schäden am Gerät die Folge sein.

Avertissement: Avant de monter l'appareil sur le bâti, assurez-vous que l'étagère peut en supporter le poids sans en compromettre la stabilité. Cela pourrait, dans le cas contraire, entraîner des blessures ou des dommages matériels.

For more information about flat surface installation or rack installation using the mounting brackets installed on the 7100G-Series chassis, see “Installation” on page 2-1.

C-2 Optional Rack Mount Rail Kit Installation

Required Order of Installation

1. Remove the rack mount ears from the chassis

2. Attach the adapter plates to the chassis

3. Install the rail assemblies in either a four post rack (see “4-Post Rack Mount Installation” on page C-5) or a two post rack (see “2-Post Rack Mount Installation” on page C-7)

4. Install the chassis in the rack.

Removing the Rack Mount Ears from the 7100G-Series Chassis

Remove the rack mount ears from both sides of the 7100G-Series chassis before continuing with the mounting kit installation. See Figure C-1.

Figure C-1 Removing the 7100G-Series Chassis Rack Mount Ears

1 Rack mount ear 2 Rack mount ear screws

The removed rack mount ears and screws are not used in any mounting kit installation procedures.

Installing the Adapter Plates

Two adapter plates come with the mounting kit. Adapter plates are used to secure the chassis to:

• The rail and extension assemblies used in the 4-post rack configuration (see “Rack Mount Rail

with Attached Extension Assembly Installation” on page C-6)

• The rail and mid-bracket assemblies used in the 2-post rack configuration (see “Pre-

Installation Tasks” on page C-8)

• The adapter plates can be installed in either a flush or a recessed configuration of up to 1.5 inch.

Enterasys 7100G-Series Hardware Installation Guide C-3

Installing the Adapter Plates

The 7100G-Series chassis can be configured for air intake on either the chassis switch I /O port side or the power supply side. Adapter plate installation must align the adapter plate ears with the air intake side of the chassis.

If you have not verified the power supply and fan module air flow for the chassis you are installing, see “Power Supply Air Flow and Switch Fan Module Air Flow” on page 2-4 for information on determining air flow direction for your chassis before installing the adapter plates.

See “Reversing the Fan Module Air Flow” on page 2-5 if the current fan module air flow direction does not match the intended chassis air flow direction.

To install the adapter plates:

Note: The side air vents are intentionally covered by the adapter plates in certain mounting configurations. The 7100G-Series switch cooling design is from front to back, not side to side.

1. Place the adapter plates on each side of the chassis with the ear end toward the air intake side of the chassis, ear flange pointing away from the chassis. Figure C-2 shows the correct orientation for a chassis with air flow from switch I/O port side to power supply side.

2. Align either the flush mount adapter plate screw holes (Callout 2) or the appropriate recess mount adapter plate screw holes with the three chassis screw holes on each side of the chassis. Callout 3 identifies the screw holes used to recess the chassis by .5, 1.0, or 1.5 inches

Note: When recess mounting, use care that the installation does not result in openings above and below the chassis face at the inlet side that allow for hot air recirculation from the exhaust side of the rack or cabinet. This is especially the case for a cabinet with enclosed sides where the cold and hot aisles are meant to be isolated.

3. Insert and tighten three of the six 6-32 flat head screws that come with the mounting kit in three places on each side of the chassis.

Rack Mount Rail with Attached Extension Assembly Installation

Refer to Figure C-4 on page C-6 as you perform the following procedure.

To install the rack mount rail with extension assembly:

1. Adjust the length of the two assemblies (callout 1) to agree with the distance between the outer face of the vertical rack posts. The screws (callout 5) holding the assembly together may need to be loosened slightly to allow for the adjustment. Retighten any loosened screws once the adjustment has been made.

2. Install the side of the assembly labeled “right front” (callout 2) on the front (cool air inlet) right rack post. Secure the assembly to both the front and rear posts, using rack appropriate screws or fasteners that you supply.

Do not use the middle hole when securing the assembly to the rack post. The middle hole is used to secure the adapter plate (previously installed on the chassis) to the assembly.

3. Repeat Step 2 for the assembly labeled “left front”.

Overview

About PoE (Power over Ethernet)

This appendix provides an overview of Power over Ethernet technology and how it is implemented in relation to the 7100G-Series devices.

Power over Ethernet (PoE) refers to the ability to provide operational power through the same Ethernet cabling to a PD (powered device) connected to a data network. Modern Ethernet implementations employ differential signals over twisted pair cables. This requires a minimum of two twisted pairs for a single physical link. Both ends of the cable are isolated with transformers blocking any DC or common mode voltage on the signal pair. PoE exploits this fact by using two twisted pairs as the two conductors to supply a direct current. One pair carries the power supply current and the other pair provides a path for the return current. While several proprietary legacy implementations of PoE have been deployed by LAN equipment vendors, in 2003 the IEEE published the IEEE 802.3af-2003 specification, which is part of the 802.3 suite of standards.

The 7100G-Series devices that support PoE are fully compliant with the IEEE 802.3af and 802.3at standards. They support the standard resistor-based detection method, as well as AC disconnect capability.

Each PD has a PDC (Powered Device Classification) that is transmitted to the device for power management purposes. Table D -1 lists the classifications and the associated power ranges based on the 802.3af standard. This table will be updated with 802.3at class information when the 802.3at draft is ratified.

Table D-1 Powered Device Classifications

Class Usage PD Maximum Power Range Usage

0 Default 0.44 to 12.95 Watts 1 Optional 0.44 to 3.84 Watts 2 Optional 3.84 to 6.49 Watts 3 Optional 6.49 to 12.95 Watts 4 Not Allowed Reser ved for Future Use

Proprietary PD Detection

7100G-Series devices support a subset of the currently deployed proprietary PoE methods. This includes support for Cisco PDs, including a proprietary capacitor based detection scheme.

Enterasys 7100G-Series Hardware Installation Guide D-1

PoE Port Status LEDs

The PoE port status of each 10/100/1000 Mbps RJ45 port is indicated by the two-color RX and TX LED display for each port. To observe the PoE port status indications, you must switch the device from the default RX/ TX status mode to the PoE Port status mode using the red PoE button. PoE status will be displayed on port LEDs for approximately 30 seconds and then returns to link status display mode as described in section “LEDs” on page 3-1.

Table D-2 PoE LED Status

Rx LED Tx LED Description

Green Off Port is delivering power. Amber Off Connected device is requesting power. Off Amber Connected de vice has exceeded power limit or faulted. Off Off No PoE on port.

Allocation of PoE Power to Devices

The 7100G-Series firmware determines the power available in the device for PoE based on power supply status and power supply redundancy mode. The system calculates and reserves the correct amount of power required by the device and then makes the balance of power available for PoE. When any change is made to the power supply status or redundancy mode, the firmware recalculates the power available for PoE.

The power available for PoE is distributed based on the configured allocation mode:

• Automatic mode (default), in which available power is distributed evenly. Any change in available power, due to a change in power supply status or redundancy mode, will trigger an automatic redistribution of power.

• Manual mode, in which the power budget is manually configured, using either CLI commands or the MIBs. The wattage configured cannot exceed the total power available on the switch for PoE.

The configured wattage assignment is used to calculate the total available PoE power. If the total available PoE power changes, a redistribution of available power will occur, applying the calculated percentage.

If the PoE power needed or requested exceeds the power available, the system will generate an SNMP trap to notify the system manager.

For more information on configuring allocation mode, see the Enterasys 7100G-Series CLI Reference Guide.

Power Distribution Upon Power Supply Removal or Addition

When a power supply is removed, the device responds to the decrease in available power by doing the following:

1. Detecting the power supply removal and recalculating available power.

2. Subtracting the power capacity for its base system from available power.

3. Distributing remaining power equally for PoE.

4. Dropping support to PoE devices as necessary to stay within the programmed maximum power.

D-2 About PoE (Power over Ethernet)

When a power supply is added, the device responds to the increase in available power by doing the following:

1. Detecting the power supply addition and recalculating available power.

2. Subtracting the power capacity for its base system from available power.

3. Distributing remaining power equally for PoE.

Management of PoE Power to PDs

You can configure how the device makes power available to attached powered devices (PDs):

• Real-time mode (default), in which the PoE controller calculates the power needed by a PD based on the actual power consumption of the attached devices.

• Class mode, in which the PoE controller manages power based on the IEEE 802.3at definition of the class limits advertised by the attached devices. In this mode, the maximum amount of power required by a device in the advertised class is reserved for the port, regardless of the actual amount of power being used by the device.

For more information on configuring power management mode, see the Enterasys 7100G-Series CLI Reference Guide.

Environmental Guidelines

Enterasys Networks provides high quality and reliable products. To ensure customer satisfaction and the continued reliable operation of our products, installation and operation must comply with the environmental guidelines as described in our product documentation. This document references limits on operating temperature and humidity. Failure to operate the equipment in these prescribed ranges can result in reduced performance and damaged equipment. Failure to comply with these limits and guidelines may void the product warranty and it may also exclude the equipment from support entitlements of any applicable maintenance contract agreements. The following information describes these limits and recommendations in further detail.

Temperature and Humidity Guidelines

Operating Temperatures

All equipment must operate within the prescribed temperature and humidity ranges specified in Enterasys documentation. Operation of the equipment outside these limits may result in damaged equipment and/or reduced performance and reliability. This may require reliable, monitored and 24x7 operation of climate control systems (heating and air conditioning).

Inlet Air Temperature Measurement

Operating temperature maximums and minimums are limits on the ambient air temperature entering the switching equipment. This area is located within 1 inch of the main equipment inlet. This is not necessarily the same air temperature throughout the room.

Cooling Air

Careful consideration is needed when mounting this equipment. Proper inlet and exit spaces must be allowed to get fresh, cool air into the equipment and to allow hot exhaust air to exit away from the equipment. Blocked venting can result in an overheating condition that can damage the equipment. Pay close attention to cable ingress and egress routing to verify that cabling is not blocking venting.

Power Conditioning

Enterasys products are rated to be used with internationally accepted AC input parameters. It is important that these parameters are monitored and verified to operate as expected for the ratings that apply to the equipment installed. Surges and excessive noise outside of these prescribed ranges in the power circuits feeding this equipment may cause permanent damage to the equipment installed and must be monitored and prevented.

Enterasys 7100G-Series Hardware Installation Guide E-1

Temperature and Humidity Guidelines

Airflow Concerns for Closed Racks

Note: The 7100G-Series switch directs air flow from front to back, not side to side.

When placing Enterasys switches into enclosed racks, rack exhaust fans must be considered if the rack does not contain adequate inlet and exit venting. These fans may be needed to help exhaust hot air from the rack. They must be sized properly to exhaust the collective volumetric flow from all equipment within the rack.

Figure E-1 illustrates the ideal configuration for a fully vented closed rack. All panels are vented,

and side-to-side cooled sub-systems are flowing in the same direction.

Cool air ingress through the bottom of the rack must be carefully allowed to enhance overall system airflow and prevent stagnant air recirculation. This may need to be confirmed through thermal testing at the installation site.

Figure E-1 Closed Rack Ideal Configuration

Airflow Concerns for Open Racks

Note: The 7100G-Series switch directs air flow from front to back, not side to side.

Equipment with different air flow cooling patterns, such as front to back or side to side, can present special concerns. Recirculation of heated air through equipment is unwanted because it increases the inlet temperature which causes the equipment components to operate at elevated temperatures. Likewise, equipment in neighboring racks must be planned to prevent hot air exhaust from one system being pulled into the inlet of an adjacent system.

Figure E-2 illustrates the ideal configuration for an open rack. All sub-systems flow in the same

direction, as shown by the white arrows.

Figure E-2 Open Rack Ideal Configuration

Temperature and Humidity Guidelines

Figure E-3 on page E-4 below shows a non-ideal configuration for an open rack, where sub-

systems with mixed flow directions (white arrows) are combined in one rack. Circular red arrows show potential for hot air recirculation.

Figure E-3 Non-ideal Open Rack Configuration

Non-ideal flows should be avoided or mitigated and confirmed through thermal testing.

Figure E-4 below shows a non-ideal open rack configuration containing sub-systems with mixed

flow directions (white arrows). This configuration shows mitigation of potential hot air recirculation by leaving a gap in the rack population.

Figure E-4 Mitigated Non-ideal Open Rack Configuration

E-4 Environmental Guidelines

Dust Mitigation and Prevention

Figure E-5 below shows another mitigation strategy for open racks containing sub-systems with

mixed flow direction. Mitigation of potential hot air recirculation is achieved by separating unlike systems with products having front to back airflow patterns.

Figure E-5 Another Mitigated Non-ideal Open Rack Configuration

Dust Mitigation and Prevention

Dust accumulation on inlet and exit venting is not uncommon after prolonged use. In dustier environments this accumulation can be much quicker.

Enterasys strongly recommends routine maintenance to check for clean inlet and exit vents on this equipment. Over time, dust accumulation can create vent blockages, thereby decreasing airflow and increasing component temperatures, resulting in reduced reliability. Recommended maintenance should start with monthly inspections and be adjusted based on dust accumulation levels.

Tab le E- 1 on page E-6 notes the maximum dust and debris accumulation limits for room

environments as a reference.
