Installation Procedure

Installing an ATM Interface Module into the 7-Slot Chassis
If you are not using a particular slot at this time, 3Com recommends that
you leave its protective faceplate on.
To install the ATM Interface Module into the chassis:
CAUTION: Before you start the installation process, see "Safety
Precautions" on page 17.
1 Pick up the ATM Interface Module and hold it a horizontal position, with
the ports facing you, the LEDs at the left, and the daughter cards facing
upward (Figure 41).

CAUTION: Be careful not to twist or bend the module as you insert it.
2 Align the module with the proper slot guides as described, and slide the
module partially into the slot. Make sure that the left and right edges are
in the same slot.
3 Open the module ejector handles completely.
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.
4 Push on the large captive screws to further insert the module, until it is
completely into the slot and the module ejector handles begin to close
(Figure 42).
