replaced. In cases where additional PM cards are needed, the face plate for an available
front-mounted slot must be removed. The following procedure describes this operation
3.9.1
Preparation for Installing and Removing PMs
STOP!!!
Be sure the power cord is unplugged
from the chassis before attempting to remove
and/or replace any PM cards.
Failure to do so may result in damage to the unit
and will void the warranty.
Caution- Proper Static Discharge: The port modules ( like most electrical equipment) are
sensitive to static discharge. Use proper ESD measures, when handling port
modules.
Step 1. Remove Chassis Cover
To make the installation of port module easy, the top cover is separated in two parts
called “front-top” and “rear-top”. There are 6 screws located on front-top of the unit
and two screws each on the left and right edges. Remove these screws. Once these are
removed, the front-top cover is easily lifted off the chassis base.
When the chassis front-top cover has been removed, the interior of
the unit is exposed.
