EMC CX200-Series DPE2 Hardware Reference
The Standby Power Supply (SPS)
About the SPS
A 1000-watt dc SPS can provide backup power for one CX200 power
supply and storage processor. The SPS provides higher availability
and allows write caching — which prevents data loss during a power
failure — to continue. A faulted or not fully charged SPS disables
write caching.
The SPS rear panel has one ac inlet power connector with a power
switch, an ac outlet for the CX200, another ac outlet which you
should not use in CX200 configurations, one data connector to the
storage processor, and status lights.
IMPORTANT:
Improper storage and handling of an SPS will render the
warranty null and void. Please see Appendix A for appropriate SPS storage
requirements.
Figure 4-1 shows the SPS unit, removed from its cabinet mounting.
