Replacing or Adding
a 16-Port
Asynchronous
Module
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”.
