Nortel Networks BCM1000 Shutting down the system hardware, Removing the top cover from the unit

Chapter 15 Preparing hardware for maintenance or upgrades 169

Shutting down the system hardware

After the system has gracefully exited from the software, you can shut down the hardware.

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.

Follow these steps to ensure a safe shutdown of the system.

1Remove 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.

2Disconnect the base unit and expansion unit power cords from the ac outlet.

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.

3Ensure 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.

1Attach one end of the grounding strap to your wrist and the other end to a grounded metal surface.

2Remove the two screws from the cover, at the back of the unit.

3Lift the back of the cover and slide it back and up. Refer to Figure 74.
