Removing the Cover
Replacing or Adding
a 16-Port
Asynchronous
Module
Follow these steps to remove the server cover:
1 Shut down the server, as described in "Shutting Down".
WARNING: Before removing the cover, be sure the unit is turned off and the
power cord is either disengaged from the unit's receptacle or unplugged
from the wall socket.
2 If the server is mounted in a rack, remove it from the rack. Remove the
rack-mounting brackets from the sides of the server.
3 Use a #1 Phillips screwdriver to remove the black screws on the sides of the
cover.
4 Grasp both sides of the cover and carefully lift it off.
The following procedure describes replacing or adding a 16-port
asynchronous module to a CS/3000 series server that has already been
turned on and has been running communications server software. For
instructions on installing a 16-port asynchronous module in a server that
has never been turned on, refer to "Installing 16-Port Asynchronous
Modules".
This procedure requires you to handle a 16-port asynchronous module.
Whenever you handle one of these modules, adhere to the following ESD
guidelines:
Keep the new module in its antistatic bag until you are ready to install it.
Do not touch pins, leads, or solder connections on the board.
Handle the board by the edges only.
Observe proper grounding techniques, including using a foot strap and
grounded mat or wearing a grounded static discharge wrist strap.
You need a #1 and a #2 Phillips screwdriver and a small slotted screwdriver.
To replace or add a 16-port asynchronous module, follow this procedure:
1 Make sure server power is off and the power cord is unplugged.
2 Remove the cover, as described in "Removing the Cover".
