On the SRPUs, there are also LEDs indicating the working status of the power modules. For details,
refer to related description about the power LEDs on the SRPUs other than the LSQ1MPUA0 in
Chapter 1 “Product Overview”.
Troubleshooting the PSR2800-ACV
On the right of the PSR2800-ACV power module panel are the input LED, output LED, fan LED, PoE
input LED, and PoE output LED. Compared with the PSR1400-A power module, the PSR2800-ACV
power module has two power inputs: one for system power input and the other for PoE power input. The
meanings of the PoE power LEDs are similar to those of the system power LEDs. For the meanings of
these LEDs and for the troubleshooting procedure, refer to section "Troubleshooting the PSR1400-A"
on page 7-2.
Troubleshooting the PSR6000-ACV
On the PSR6000-ACV power module panel are the system power input LED (SYS IN), system power
output LED (SYS OUT), system power fan LED (SYS FAN), PoE input LEDs (PoE IN1, PoE IN2, and
PoE IN3), PoE output LED (PoE OUT), and PoE power fan LED (PoE FAN).
Compared with the PSR1400-A, the PSR6000-ACV has four AC power inputs: one for system power
input and three for PoE power input. The meanings of the PoE power LEDs are similar to those of the
system power LEDs. For the meanings of these LEDs and for the troubleshooting procedure, refer to
section “Troubleshooting the PSR1400-A on page 7-2.
