3.1.2 Power Supply of Equipment
3.1.2.1 Power Supply Range of the Power System
The ZXDSL 9210 equipment adopts distributed power supply. Two groups of –48 VDC
power supply (one active and the other standby) are input from two sockets on a
backplane. To ensure that the equipment runs stably, the input operating voltage ranges
from –57 VDC to –40 VDC. The primary power supply and battery group must serve
as mutual backups to ensure uninterrupted operation of the equipment in case of any
power failure.
3.1.2.2 Power Consumption Indices
Power consumption for a single frame (full configuration): 950 W (calculated
according to 1 × SCBF+15 × ATIGN+15 × PSUT+1 × LTC).
Table 3.1-1 shows the power consumption indices of the boards of ZXDSL 9210.
