Business Communications Manager
MSC FRU replacement process
P0607273 03
Addendum contents
The procedures in this document replace the procedures in your Business Communications
Manager (BCM) installation and maintenance guide to remove, replace, and configure the
media services card (MSC) field replaceable unit (FRU). These procedures help you correctly
set up the system to receive a new MSC and to download the correct operating files from the
system hard disk.
The procedures to prepare the system for maintenance, and to remove and replace the base
function tray, are the same procedures as found in your installation and maintenance guide.
Warning: Only qualified personnel must perform these procedures. Failure to
follow these steps in sequence to replace an MSC results in an inoperable system.
Ensure that all procedures performed on the hardware occur in a static safe
environment.
Equipment note: BCM200/BCM400
Most internal diagrams in this document show the BCM200 hardware configuration. The
BCM400 base function tray is the same. One exception is that the BCM400 MSC has space for
four processor expansion cards (PECs), whereas the BCM200 supports a maximum of two.
The procedure to remove and replace the tray and the MSC is the same for both models. Any
differences are noted where appropriate,
This addendum contains the following sections. Ensure that you follow each section in
sequence.
