Installing and
Removing the
7600 Card Modules

The following section discusses how to install and remove the 7600 Card
and its optional modules.

Installing the 7600

Card Module

To install the 7600 Card module into the CELLplex 7000 chassis, perform
the following steps:

1 Pull the ejector tabs on each side of the front panel to their outermost

position and orient the 7600 Card in front of the selected slot of the
CELLplex 7000.

2 Place the module between the runners of the selected slot and slide it

into the CELLplex 7000 chassis until it reaches the backplane and can go
no further.

While sliding the 7600 Card into chassis, make sure that the loose hex
spacers on the card do not interfere with inserting the module.

3 Make sure the ejector tabs are still in their outermost position and give

the module a firm push to ensure that the card has fit snugly into the
connectors on the backplane.

4 Push the ejector tabs to their innermost position to lock the module in

place.

You may have to apply pressure on the tabs in order to ensure that the
board is firmly in place in the connectors in the backplane. An audible
click indicates that the connectors have engaged.

5 Pull the ejector tabs to the middle position.

6 Tighten the module’s securing screws on the front panel.

Removing the 7600

Card Module

To remove the 7600 Card from the CELLplex 7000 chassis perform the
following steps:

1 Release the screws on the front panel.

2 Pull the ejector tabs to their outermost position and carefully slide the

module out.

The 7600 Card module can be inserted into or removed from the chassis
of the CELLplex 7000 ATM switch while the switch is powered up
(i.e., hot-swapped).
