Installation and Maintenance Guide
Shutting down the system hardware
After the system has gracefully exited from the software, you can shut down the hardware.
Follow these steps to ensure a safe shutdown of the system.
1 Remove the cables from the front of the BCM1000 and BCM1000e, if there is one. This
includes the data connections on the media services card (MSC).
Mark the cables so you can ensure they get reconnected correctly.
2 Disconnect the base unit and expansion unit power cords from the ac outlet.
3 Ensure you have room to access the part you are working on. Remove the base unit from the
rack, if necessary.
Removing the top cover from the unit
You must remove the top cover to access any of the internal components of the BCM1000.
1 Attach one end of the grounding strap to your wrist and the other end to a grounded metal
surface.
2 Remove the two screws from the cover, at the back of the unit.
3 Lift the back of the cover and slide it back and up. Refer to Figure 100 .

Warning: You must remove all of the connections to the Business Communications
Manager hardware before you power the system down. Failure to disconnect lines before
power down can cause damage to the system.
Warning: You must disconnect power from the BCM1000 after you have performed a
Unified Manager shutdown. The base unit cannot start operating again until after power
has been disconnected and then reconnected.
