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.

Verifying Module The GEN Interface Modules each have one Module Status LED and twoOperation Port Status LEDs. Watch the LEDs during systempower-onto verify

proper module operation. During the power-ondiagnostic test, both the Module Status and Port Status LEDs flash for approximately 1 second, and then reflect the active status of the module as described inTable 3.

.

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.

Due to the dual media (single-modeand multimode) support of the1000BASE-LXmodule, anoffset-launchmode-conditioningpatch cord assembly is required to meet the specifications for multimode (MMF) operation. This patch cord is not required for single mode (SMF) operation. Patch cords come in various lengths and can be ordered from Siecor Operations(800-743-2675,fax:828-327-5973).The following table lists the part number information:
