PSU Slot 1

The Aruba 7280 controller includes a PSU slot 1 that has a filler panel covering the opening. PSU slot
1 is for an additional power supply module that may be required for redundancy. PSU slot 1 can hold
the same power supply module as PSU slot 0. For more details, see “PSU Slot 0” on page17.

Grounding Point

To meet safety and electromagnetic interference (EMI) requirements and to ensure proper
operation, the controller must be adequately grounded before power is connected. Connect a
grounding cable to earth ground and then attach it to the chassis grounding point using two screws.

Comply with electrical grounding standards during all phases of installation and operation of the
product. Do not allow the controller’s chassis, network ports, power supply, or mounting brackets to
contact any device, cable, object, or person attached to a different electrical ground. Also, never
connect the device to external storm grounding sources.

Fan Module

The Aruba 7280 controller is equipped with five field-replaceable, hot-swappable fan modules. Each
fan module features a fan that pull air through the chassis from the front through to the rear. The
7280 controller can tolerate the failure of a single fan while maintaining a safe operating temperature
for the controller.

The 7280 controller is not compatible with fan modules from other Aruba hardware platforms.

The LED behavior in the fan module is as follows:

 Green - Fan module is operational

 Amber - Fan module is faulty

16 | 7280 Controller Aruba 7280 Controller | Installation Guide

Hot Swapping

Hot swapping allows you to replace a failed fan module, making it unnecessary to shut down the
7280 controller during the replacement procedure.

PSU Slot 0

The Aruba 7280 controller is equipped with a 550W power supply, which is an autosensing, load­sharing, redundant power supply module that supports an input voltage of 100 VAC to 240 VAC. Each
power supply has a country-specific power cord for connection to an AC power outlet.

The Aruba 7280 controller is shipped with one hot-swappable, field-replaceable, AC power supply in
PSU slot 0 and one filler panel in PSU slot 1. The controller can operate with one or two active power
supplies, depending on the demands of your configuration. The following sections describe features
of the 550W AC power supply:

Load Sharing

Load sharing occurs when more than one power supply of the same rating is installed in the 7280
controller and turned on. Load sharing divides the total power load of the controller among all
available power supplies. Since the power supplies work together, the effective power capacity of the
controller is increased with each additional power supply.

Redundancy

With power redundancy, the 7280 controller can continue normal operation even when a power
supply fails or is turned off. When multiple power supplies are installed, if one becomes unavailable
(fails, or is turned off or removed) the remaining power supplies will attempt to provide full power for
the device. If the device’s total power load does not exceed the combined rated output of the
remaining, operational power supplies, the controller will continue to operate.

Hot Swapping

Hot swapping allows you to replace one failed power supply while the others provide full power. This
makes it unnecessary to shut down the 7280 controller during the replacement procedure.

Hot swapping is supported only when power redundancy is in effect. This requires that after the
target power supply is removed, the device’s total power load does not exceed the combined rated
output of the remaining power supplies.

Never insert or remove the a power supply module while the power cord is connected to it. Verify that cord has
been disconnected from the power supply before installation or removal.

LED Indicators

The following table shows the LED indicators and the corresponding status:

Table 13 Power Supply Module LED
