Uninstalling an RPS17 Power Supply Unit (PSU)
You can uninstall an RPS17 PSU from EPS4000 while the device is powered on and running.
NOTE
While uninstalling a PSU, wear an ESD wrist strap.
DANGER
For safety reasons, the ESD wrist strap should contain a series 1 megaohm resistor.
Perform the following steps to uninstall an RPS17 PSU.
1. Put on the ESD wrist strap and ground yourself by attaching the clip end to a metal surface (such as
an equipment rack) to act as ground.
2. Lift the PSU latch and gently slide the PSU out from the slot.

Connecting the EPS4000 cord
There are two types of EPS4000 cords available, 1:1 and 1:2. The 1:1 cord can deliver 720 Watts at
54 Volts to one switch. The 1:2 cord can deliver 360 Watts at 54 Volts to each of two switches from
one port on the EPS4000 power supply. Both cords deliver up to 120 Watts at 12 Volts. You must use
a 1:2 cord if you want an ICX 7250-48P device to share 54-V power with another device. Both 1:1 and
1:2 cords will deliver only 360 Watts of 54-V power to an ICX 7250-24P device.
