Installation and Maintenance Guide
Remove the processor expansion card (PEC)
Use this procedure to remove PECs from a Business Communications Manager MSC.
1 Ensure you have a current data backup of your system.
2 Shut down the system using the Shutdown command. For details refer to “Shut down the
system software” on page 145. When complete, continue to the next step of this procedure.
3 Set up the server for maintenance, as described in “Shut down the system hardware” on page
146. When complete, continue to the next step of this procedure.
4 Disconnect the Business Communications Manager from the wall power outlet.
5 Attach one end of the grounding strap to your wrist and the other end to a grounded metal
surface.
6 Partially remove the base function tray from the platform base chassis. Ensure you do not
pinch, stretch or damage any cables.
7 Grasp the top edge of the PEC you want to remove and it pull out. Place the PEC in a safe and
static-free container. Refer to Figure 154.
Warning: Possible data loss
Ensure that you do not touch the PEC casing to any of the components on the MSC. This
may cause shorting, which can erase memory or cause a loss of telephony programming.
If this occurs, complete the removal of the PEC, and then restore the data from your
backup medium (upon re-installation - see “Install a processor expansion card (PEC)” on
page 233).
Warning: Protect the hardware components against damage from electro-static
discharge. Always wear a ground wrist strap before you handle components. Always place
the components in static-free container.
