Standby Power Supply (SPS)

Two SPS units fit in a tray beneath the CX700 to which they connect.
Figure 4-2 shows the SPS in a cabinet with a CX700 and DAE2.

SPS Status LEDs
Light
Meaning When Lit
Active - Green
When this LED is steady, the SPS is ready and operating
normally. When this LED flashes, the batteries are being
re-charged. In either case, the output from the SPS is
supplied by ac line input.
On battery - Amber
The ac line power is no longer available and the SPS is
supplying dc output power from its battery. When battery
power comes on, and no other online SPS is connected
to the SPE, the file server writes all cached data to disk,
and the event log records the event.
Replace battery - Amber
The SPS battery is not fully charged and may not be able
to serve its cache flushing function. With the battery in
this state, and no other online SPS connected to the
SPE, the storage system disables write caching, writing
any modified pages to disk first. Replace the SPS as
soon as possible.
SPS fault - Amber
The SPS has an internal fault. The SPS may still be able
to run online, but write caching cannot occur. Replace the
SPS as soon as possible.
