Each GEN Interface Module has two ports on the front (see Figure 1) as well as two ports on the rear of the module (not shownin Figure 1) that connect to the chassis backplane. Because the front ports have apass-throughfunction to the rear ports, they share port numbers

1 and 2 with the rear ports.

In the 16-slotchassis, you install modules vertically with the LEDs at the top. In the7-slotchassis, you install modules horizontally, as shown inFigure 1.

6 2-PORT1000BASE-SX AND2-PORT1000BASE-LX GIGABITETHERNETINTERFACEMODULESQUICKSTARTGUIDE

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.

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.
