power budget is automatically adjusted accordingly. Power management will occur as described in the
ExtremeXOS 12.0 Concepts Guide
, Power over Ethernet section.
Disconnecting the EPS-C/EPS-600LS.
To manually disconnect an EPS-C or to remove the EPS-600LS
modules, the recommended practice is to disconnect each of the EPS-600LS modules one at a time,
pausing two seconds between each EPS-600LS disconnect.
This enables a graceful power transition from the external PSUs to the internal PSU.
Example: Two active EPS-600LS modules in an EPS-C
a
Unplug one EPS-600LS unit from its power source.
PoE power is automatically reduced to 370 watts and the internal PSU is enabled providing
redundant 370 watt PoE power.
b
Wait at least two seconds before disconnecting the remaining EPS-600LS unit.
c
Unplug the second EPS-600LS unit from its power source.
The internal PSU is already enabled and provides uninterrupted 370 watts of PoE power.
NOTE
After an EPS-600LS unit is disconnected from its power source, it may be removed from the EPS-C. See
“Removing an EPS-600LS” on page 334
for complete disconnect and removal details.
d
Disconnect the EPS-C from the switch.
Installing an EPS-C Chassis
This section describes the installation process for the Extreme Networks EPS-C (External Power Supply
Chassis 10912). The EPS-C chassis holds one, two, or three compatible EPS-600LS units (External Power
Module 10913). The EPS-C is intended for use only with Summit X450e-48p or X250e-48p switches.
Pre-Installation Requirements
You need the following tools and equipment to rack mount the EPS-C:
●
# 1 Phillips screwdriver
●
Rack mount kit
Rack-Mounting the EPS-C
CAUTION
Do not use the rack mount brackets to suspend the EPS-C from under a table top or desk, or to attach the EPS-C
unit to a wall.
To rack-mount the EPS-C:
1
Place the EPS-C upright on a hard flat surface.
2
Remove the mounting bracket kit (including screws) from the packaging.
3
Locate a rack mount bracket over the mounting holes on one side of the unit.
