EPS/RPS LED Behavior
T/M
(green – ports
21 - 24 or 45-
48)
On
For the dual-personality ports, indicates the enabled connector:
•
if the “T” is on, the 10/100/1000Base-T RJ-45 connector is enabled.
•
if the “M” is on, the mini-GBIC connector is enabled.
Fan Status
(green)
On
Normal operation, all fans are ok.
Blinking*
One of the unit’s fans has failed. The switch Fault LED will be blinking simultaneously.
RPS Status
(green)
On
Blinking
Off
Normal operation.
An HP ProCurve EPS/RPS unit is connected and operating correctly.
The EPS/RPS could be powering the unit - see table below.
The EPS/RPS is connected but may be powering another switch or the EPS/RPS has
experienced a fault.
The EPS/RPS is not connected or is not powered.
* The blinking behavior is an on/off cycle once every 1.6 seconds, approximately.
