ESD Safety Information

Electrostatic discharge (ESD) can damage components of the module. ESD, which occurs when a GEN Interface Module is improperly handled, can cause complete or intermittent failures.

CAUTION: To preventESD-relateddamage:

Always wear an ESD wrist strap (not provided) when you handle a GEN Interface Module, ensuring that the strap makes good skin contact.

Keep the GEN Interface Module in its antistatic bag until you are ready to install it.

Handling Precautions When you handle a GEN Interface Module, follow these precautions:

Always handle the module by its front panel only.

Do not touch the components, pins, leads, or solder connections.

Do not twist or otherwise force the module into the chassis when you insert it into the module slot guides.

Before you push the module into the chassis, make sure that the module ejector handles are open.

To slide the module into the 16-slotchassis, match the upper and lower module guides; in the7-slotchassis, match the left and right module guides.

Unpacking Use the following procedure when you unpack a GEN Interface

Instructions Module:

1Verify that the GEN Interface Module is the correct product by matching the order number that is listed on the shipping box label to the order number that is listed on your sales invoice (3CB9LG2MC or 3CB9LG2SC).

2Remove the module, in its antistatic bag, from the shipping box.

3Ensure that the box also contains:

If the listed contents are not in the shipping box, contact your supplier.

All shipping boxes are reusable. After you remove the contents, replace the packing materials in the box and store it for future use.

4Remove the GEN Interface Module from its antistatic bag and inspect it for physical damage.

CAUTION: Handle the module by the front panel only. Do not touch any components, pins, leads, or solder connections.

If the module appears to be damaged, replace it in its antistatic bag and shipping box, and contact your supplier.

Installation Before you install a GEN Interface Module, make sure that thePrerequisites CoreBuilder 9000 chassis is properly installed in a rack, on a table, or

on a shelf, according to the instructions in the CoreBuilder 9000 Enterprise Switch Getting Started Guide and the16-Slot Chassis Quick Installation Guide or7-Slot Chassis Quick Installation Guide.

You need a flat-bladescrewdriver to complete the module installation.

Order of Installation 3Com recommends that you install CoreBuilder 9000 modules in theActivities following order:

1Management Modules

One Enterprise Management Engine (EME) is required (order number 3CB9EME). A second EME or an Enterprise Management Controller (EMC) is optional (order number 3CB9EMC). By installing the management modules first, you can complete the required system-levelsetup procedures before you add other modules to the chassis. For more information, see the following documents:

Enterprise Management Engine User Guide

Enterprise Management Engine Quick Start Guide

Enterprise Management Controller Quick Start Guide

2Switch Fabric Modules

Because you manage a GEN Interface Module through the primary GEN Switch Fabric Module, you must install one GEN Switch Fabric Module first. In the 16-slotchassis, a second GEN Switch Fabric Module is optional. See theGigabit Ethernet Switch Fabric Module Quick Start Guide for more information.

3Interface Modules

Install all interface modules, such as the 2-port1000BASE-SXGEN Interface Module, the2-port1000BASE-LXGEN Interface Module, or the36-port10/100BASE-TXFast EthernetRJ-45Layer 2 Switching Module, last. You can install interface modules in any order, but see your module documentation for chassis slot restrictions and recommendations. For restrictions and recommendations for the GEN Interface Modules, see“Module Placement in the Chassis” next in this guide.

2-Port1000BASE-SXand2-Port1000BASE-LXGigabit Ethernet Interface Modules Quick Start Guide

Module Placement in Note the following chassis slot restrictions and recommendations whenthe Chassis you choose a chassis slot for a GEN Interface Module.

In the CoreBuilder 9000 7-slotchassis:

Do not install the module in slot 7. This slot is reserved for a GEN Switch Fabric Module.

Install the module in slot 1, 2, 3, 4, 5, or 6.

In a CoreBuilder 9000 16-slotchassis:

Do not install the module in slot 8 or 9. These slots are reserved for GEN Switch Fabric Modules.

To optimize backplane performance, install the module in slot 1, 2, 3, 4, 5, 6, 7, 10, 11, or 12.

3Com recommends that you do not install the module in slot 13, 14, 15, or 16, because these slots only have one connection to the backplane and the GEN Switch Fabric Modules (see Table 2). If you install a GEN Interface Module into one of these slots, you can only use one of the module’s front panel ports. The GEN Switch Fabric Module automatically disables the second port.

Table 1 andTable 2 list the relationship between the 24 Gbps Gigabit Ethernet (GEN) Switch Fabric Module (3CB9FG24) and the interface module slots in the7-slotchassis and the16-slotchassis, respectively. Use the information to help select a slot for your module, as well as for administration purposes after you have completed the installation.

Installing the GEN Follow this procedure to install a GEN Interface Module:

Interface Module

1Before you start the installation process, read “Safety Precautions” and“Handling Precautions” earlier in this guide.

2Select a chassis slot for your module, following the restrictions and recommendations in “Module Placement in the Chassis” earlier in this guide.

3To expose the selected chassis slot, remove the blank faceplate that covers the slot.

Save this faceplate, because you may need to cover an empty slot in the future. Empty slots must be covered to ensure proper air flow and cooling in the chassis.

4Open the module ejector handles.

5Begin to insert the module:

In the 7-slotchassis, hold the module horizontally with the LEDs on the left and insert the module using the guides on the left and the right of the slot. SeeFigure 2.

In the 16-slotchassis, hold the module vertically with the LEDs at the top and insert the module using the guides on the top and the bottom of the slot. SeeFigure 3.

CAUTION: Be careful not to twist or bend the module when you insert it.

6Slide the module into the chassis by pushing firmly at the two ends of the front panel near the ejector handles.

WARNING: Hazardous energy levels exist inside of the chassis. Do not place hands or objects into the chassis or touch components on an inserted module.

7To engage the module connectors and the chassis backplane connectors, apply forward pressure to the module front panel.

You feel a slight resistance as the connectors engage.

CAUTION: If the resistance is too great, the module connectors and the backplane connectors may not be aligned. Forcing the module into place can damage the module connectors and backplane connectors. If necessary, remove and reinsert the module, ensuring that the connectors are properly aligned. Do not tighten thespring-loadedscrews to seat the module.

If modules are already installed to the left of this module in a 16-slotchassis or installed beneath this module in a7-slotchassis, you may need to apply sideways or downward pressure on that adjacent module to have your module line up correctly in its slot. Applying this pressure compresses the thin strip ofrubber-likematerial (which exists for electromagnetic interference purposes) at the edge of the front panel of the adjacent module.

8Ensure that the module remains fully seated in the backplane connectors while you close the ejector handles.

Use one hand to hold the module in place, and use your other hand to close one ejector handle at a time until the handles are parallel with the front panel.

9To secure the module front panel to the chassis, tighten the spring-loadedscrews to a torque specification of3–5inch-pounds.

CAUTION: To ensure adequate cooling air flow and continued product safety agency compliance, install blank faceplates over all empty slots.

Managing the You configure and manage the front panel ports on the GEN InterfaceModule Module using the Administration Console, which is a command line

interface that you access from a terminal that is connected through the Enterprise Management Engine (EME).

At the command prompt, you do not connect directly to a GEN Interface Module; you manage GEN Interface Modules by connecting to the primary GEN Switch Fabric Module backplane ports that correspond to where you have installed the GEN Interface Module in the chassis. To learn how GEN Switch Fabric Module backplane ports are assigned to chassis slots, see Table 1 andTable 2 earlier in this guide.

To manage GEN Interface Module ports from the Administration

Console:

1Log in to the EME.

For information about logging in to the EME, see the CoreBuilder 9000 Enterprise Management Engine User Guide.

2At the prompt, enter:

connect <slot>.1

Where <slot> is the slot number of the module that you want to manage, and the number after the decimal point is a subslot number (the subslot number is always 1).

Because you manage the GEN Interface Modules through the GEN

Switch Fabric Module, you always connect to slot 7 in the

CoreBuilder 9000 7-slotchassis and to slot 8 or slot 9 in the

CoreBuilder 9000 16-slotchassis.

This command connects you to the primary GEN Switch Fabric Module, and the Administration Console displays the top-levelmenu prompt.

3To manage a GEN Interface Module port, enter commands for the corresponding backplane port on the primary GEN Switch Fabric Module.

For information about module commands, see the Command Reference Guide.
