Installing the GEN
Interface Module
Follow this procedure to install a GEN Interface Module:
1
Before you start the installation process, read “Safety Precautions” and
“Handling Precautions” earlier in this guide.
2
Select a chassis slot for your module, following the restrictions and
recommendations in “Module Placement in the Chassis” earlier in this
guide.
3
To 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.
4
Open the module ejector handles.
5
Begin to insert the module:
In the 7-slot chassis, 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. See Figure 2.
In the 16-slot chassis, 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. See Figure 3.
CAUTION: Be careful not to twist or bend the module when you insert
it.
6
Slide 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.
