Extreme Networks 17001 manual Pre-installation Requirements

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 “Selecting Power Supply Cords” on page 218.

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.

Installing an EPS-160 External Power Module (with EPS-T)

You can order the EPS-T chassis with one or two EPS-160 power supplies already installed. You can also order an additional power supply from your Extreme Networks reseller.

The EPS-T can be mounted in a rack or placed free-standing on a tabletop.
