To shutdown the system hardware
1 Remove the DS256 cables from the front of the BCM main unit and, if present, the expansion
unit. This includes the data connections on the MSC.
Mark the cables to ensure correct reconnection.
2 Turn off the power switch located at the back of the BCM main unit and expansion unit.
3 Disconnect the BCM main unit and expansion unit power cords from the AC outlet.
4 Ensure you have room to access the part you are working on. Remove the BCM main unit
from the rack, if necessary.
Pages 126–131, Setting initial system configurations
This section should be removed. The initial system configuration will be done after the rest of the
equipment is installed.
Pages 131, Entering the software keycodes
This section should be removed. The keycode feature is discussed in another section of the
addendum.
Pages 144-146, Telephone port and DN cross-reference
The Note on page 144 should be modified as follows.
Warning: Remove all of the connections to the BCM system before you power down the
system.
Failure to disconnect lines before you power down the system can cause damage to the
system.
Warning: You must disconnect power from the main unit after you have performed an
Element Manager shutdown. The main unit cannot start operating again until after power
has been disconnected and then reconnected.
Note: The following table is based on a system with three-digit DNs, with a start
DN of 221. If your system has longer DNs, the system automatically adds a repeat
of the first digit for each additional DN length unit. i.e. 221 becomes 2221. Also,
note on the tables below that DN numbering differs between systems that were
upgraded from BCM 2.5 software and systems that were new with BCM 3.0 or
newer software.
