7.1.1 Maintenance
This module provides maintenance advice on different hardware components of the
Alcatel-Lucent OmniPCX Office Communication Server system.
7.1.1.1 BATTERY MAINTENANCE
Alcatel-Lucent OmniPCX Office Communication Server systems (except the Alcatel-Lucent
OmniPCX Office Compact Edition) are supplied with internal batteries that provide back-up
power in the event of a mains power failure. Alternatively, all systems may be optionally
equipped with an external battery pack to provide back-up power.
To guarantee system shutdown without data loss in the event of a mains power failure or if the
mains plug is unplugged from the wall socket, replace the batteries every two years. This
maintenance operation is vital to guarantee sufficient power autonomy to allow the files to be
saved before the system shuts down.
Before replacing batteries, the system must be powered down and the power cable removed
from the mains supply.
- To replace internal batteries, the rear panel of the system cabinet must be removed and
the battery drawer pulled out.
- To replace external batteries, the external battery box must be opened.
To maintain a good balance, replace all the batteries at the same time with
batteries of the same type, from the same manufacturer and from the same batch.
Make sure you respect the correct polarities when replacing batteries. There is a
risk of explosion if the batteries are incorrectly replaced. Used batteries must be
disposed of according to the battery manufacturer's instructions.
The batteries are supplied uncharged. File saving in the event of a power failure can only be
guaranteed once the batteries have been charged; that is, about 12 hours after turning on the
system (CPU-1/CPU-2/CPU-3/CPUe-1/CPUe-2 switch in ON position).
