Preparing hardware for maintenance or upgrades

When you need to replace or update a piece of hardware on the Business Communications system, you must ensure the system is safely disconnected from the trunk lines and all electrical connections are disconnected. To replace interior components on these units, you can remove the top to access the inside of the units. Also, if you are replacing any of the PCI cards (base unit only) or any of the media bay modules, you may need to remove the front bezel of the unit.

Figure 73 provides an overview of the process for preparing the Business Communications Manager hardware for maintenance or upgrade procedures.
