Installing the Switch
Installation Procedures
Installing the Switch
These external power supplies support hot plugging of the RPS cable without
causing a reboot of the switch or causing the power supply in either of the
power supplies, or switch to shut down temporarily or permanently. For more
information refer to the documentation for the external power supplies
located on the ProCurve Web site at
www.hp.com/go/procurve/manuals
.
Operating Characteristics of the 620 RPS/EPS (J8696A)
The 620 RPS/EPS has two RPS ports, each of which can provide redundant
+12V power to a connected switch. If a switch with no AC power is connected
to an operating 620 RPS/EPS, the switch will not power on. For the switch to
receive power from the external power supply, the switch must first be
powered up then connected to the external power supply.
For redundant AC power, connect the 620 RPS/EPS to the switch using one
of the supplied RPS cables. RPS cables are 2 meters (6.56 feet) in length.
The 620 RPS/EPS also has two EPS Ports which can not be used with the
2910al Switches.
620 RPS/EPS LEDs
The 620 RPS/EPS LEDs are located on the front and back of the device. The
following illustration shows an example of the back of the 620 RPS/EPS. There
are two dual colored (green/orange) LEDs for each RPS and EPS port:
