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:
http://www.extremenetworks.com/services/
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 an Internal 600-Watt Power Supply on page 122
• Removing an Internal Power Supply on page 123
• 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.
