Pre-Installation Requirements; Installing An Eps-160 External Power Module (With Eps-T) - Extreme Networks Summit X150 Series Hardware Installation Manual

Installing Summit External Power Supplies
When the PSU is outside the chassis (not installed), do not plug the PSU into an electrical outlet. Plugging an
uninstalled AC PSU into an electrical outlet exposes you to a hazardous energy and is a potential fire hazard.
WARNING!
Always be sure that the DC circuit is de-energized before connecting or disconnecting the DC wiring harness at the
DC power socket on the rear of the EPS-150DC unit, and before connecting or disconnecting the redundant power
cord between the switch and the EPS-150DC unit.

Pre-installation Requirements

You need the following tools and equipment to install an external power supply:
Electrostatic discharge (ESD)-preventive wrist strap
●
# 1 Phillips screwdriver
●
Rack mount screws suitable for your organization's equipment rack
●
Screwdriver suitable for use with your rack-mount screws
●
AC power cord
●
An AC power cord is not included with the external power supply. You must obtain a power supply
cord that meets the requirements listed under
NOTE
When you connect an external power supply, consider all of the equipment that is connected to the power supply
circuit to ensure that the circuit is not overloaded. Use proper overcurrent protection, such as a circuit breaker, to
prevent overcurrent conditions.
The switch and each redundant power supply source should be plugged into separate branch circuits to provide
redundancy.
