Installing and Removing the Internal 600 Watt AC Power 
Supply (15412)

The Summit 300-48 600 Watt AC power supply (15412) is designed to be used in the Summit 300-48 
switch. While powering the Summit 300-48, the 600 W power supply is capable of providing 450 W of 
power to Power over Ethernet (PoE) devices connected to the 48 primary PoE ports. Refer to the 
Summit 300-48 Release Notes to determine the total available power at each port. You can obtain copies 
of these documents at the Extreme Networks web site at:

The switch has two power supply bays, so a redundant power supply can be installed. When used in 
redundant mode, the power supplies are hot-swappable. You can add a second power supply without 
powering off the switch. If redundant power supplies are installed, you can remove one of them 
without powering off the switch.

This section includes the following procedures:

Installing a cable retaining bracket

Removing cable retaining bracket

The Summit 300-48 comes with a minimum of one power supply pre-installed at the factory. Switches 
with one power supply have a metal cover plate in place of the second supply. If you install a second 
power supply, be sure to retain the cover plate in case you later decide to use only one supply.
