Table 11 describes the rear panel 1U SPS LEDs.
1U SPS RJ-12 connector
Figure 16 on page 29 shows the 1U SPS (RJ-12 or modular jack) management port (labeled
with two symbols; one depicting a telephone handset with a line through it and the other
depicting a rectangle with a line through it). Both symbols mean that you cannot connect
telephone type circuits to this connector (see the following WARNING). This port connects
the 1U SPS (A and B) ports to the SP (A and B) ports, respectively.

Led Color State Description
SPS power Green On SPS ready and operating normally; battery fully
charged
Blinking On/battery charging
— Off Off/disconnected
SPS battery Amber On AC line power is no longer available and the SPS is
supplying DC output power from the battery.
Note: When battery power comes on, and no other
online SPS is connected to the SP, the system writes
all cached data to disk, and the event log records
the event.
SPS no battery Amber On SPS battery is not fully charged and might not be
able to serve its cache flushing function. With the
battery in this state, and no other online SPS
connected to the SP, the system disables write
caching, and writes any modified pages to the disk
first. Replace the SPS as soon as possible.
SPS fault Amber On The SPS has an internal fault. The SPS might still be
able to run online, but write caching cannot occur.
Replace the SPS as soon as possible.
