Nominal Power Holdover
Multicarrier Cabinets
Two types of battery holdover are available:
● The small battery assembly provides short-term battery holdover. If AC power fails, 48
VDC batteries power the system for:
- 15 seconds in a PN cabinet
- 10 minutes in the expansion control carrier in the “A” position of a PN cabinet
● Some AC-powered multicarrier cabinets (MCCs) contain three 48-Volt batteries and a
battery charger (397C) to provide backup power in case power is interrupted. The
holdover times are identical to those above.
Single-Carrier Cabinets
A holdover circuit in the power supply allows a system to operate normally during AC power
interruptions. When AC input power fails, reserve batteries supply power to the memory and
processor circuit packs and fans for two minutes. Every port circuit pack is inactive during this
time. The power supply contains a battery charger to charge the holdover batteries.
