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 
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 uninterruptable 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:

When AC power is restored after an outage, the battery charger fully recharges the batteries 
within 30 hours.
