Battery and Charger for AC-Powered Systems
S8700 Multi-Connect systems support two different cabinet types: multicarrier
and single carrier. Single carrier cabinets are used only for PNs. 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.
AC-powered multicarrier 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 (MSS). The nominal
power holdover provided is as follows:
When AC power is restored after an outage, the battery charger fully recharges
the batteries within 30 hours.
