Table 9 describes the SPS LEDs.
SPS RJ-12 connector Figure 13 shows the 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 SPS (A and B) ports to the SP (A and B) ports, respectively.
The SPS (RJ-12) port is a LAN port not a WAN port. LAN ports contain safety
extra-low voltage (SELV) circuits, and WAN ports contain telephone-network
voltage (TNV) circuits. An RJ-45 (or TNV-type) looks the same as the RJ-12 except for
two very important differences. An RJ-45 is an 8-wire modular jack. The RJ-12 is a
six-wire modular jack. The RJ-45 plugs and jacks are wider than their RJ-12
counterparts - 7/16"vs 3/8". An RJ-45 plug won't fit into an R-J12 jack. But an RJ-12
plug will fit into an RJ-45 jack. Use caution when connecting cables. To avoid
electric shock, do not attempt to connect TNV circuits to SELV circuits.

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 file server 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 may 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 may still be able to
run online, but write caching cannot occur. Replace the SPS
as soon as possible.
