Battery and Charger for AC-Powered Systems
DEFINITY Systems support two different cabinet types: multicarrier and single
carrier. Single carrier cabinets are used only for EPNs. Both cabinet types may
be powered by either AC or DC external power source. Environmental
maintenance differs according to cabinet type and external power supply.

maintenance differs according to cabinet type and external power supply.
AC-powered Multi-Carrier Cabinets can be equipped with rechargeable batteries
that provide backup power during short power outages. Battery backup is
optional on cabinets powered by an Uninterruptible Power Supply (UPS), and is
required on those that are not. DC-powered cabinets and single-carrier cabinets
do not have battery backup, and this MO is not valid for those cabinets.

The battery backup for the J58890CH unit consists of one battery assembly and
charger. The battery backup for the J58890CE unit consists of three 48V
batteries and a battery charger. Each cabinet so equipped has its own
independent battery backup unit. When power to the cabinet is interrupted, a
warning alarm is logged against AC-POWER and the system draws power from
the backup batteries. This is known as Nominal Power Holdover (NPH). If power
is restored before the NPH time expires, the alarm is resolved. If power does not
return, error logs are saved to the Mass Storage System. The nominal power
holdover provided is as follows:
