The color coding around the RPS and EPS ports denotes that only switches
with the same exact colors can be connected to this unit. For example, if you
have a switch with the color magenta around the EPS port, it can not be
connected to the EPS ports of the HP 620 RPS/EPS.

orange)
On The unit is supplying power to a connected device.
Off One of these conditions exists:
• There is no connected device.
• A connected RPS device does not require power.
• A connected EPS device has not successfully communicated for EPS power.
Blink
orange
1
When the LED is blinking simultaneously with the Fault LED, there is a fault
condition on the port. If the Fault LED is not blinking there could be an overcurrent
condition from the connected switch.
1
The blinking behavior is an on/off cycle once every 0.8 seconds, approximately.
2
The blinking behavior is an on/off cycle once every 1.6 seconds, approximately.
