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 LED behavior in the fan module is as follows:
Green - Fan module is operational
Amber - Fan module is faulty
The 7280 controller is not compatible with fan modules from other Aruba hardware platforms.

Aruba 7280 Controller | Installation Guide 7280 Controller | 17
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, load-
sharing, 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.
LED Indicators
The following table shows the LED indicators and the corresponding status:
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.
Table 13 Power Supply Module LED

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.
Perform installation or removal of the chassis or any module in a static-free environment. Proper
use of anti-static body straps and mats is strongly recommended.
Modules must be kept in anti-static packaging when not installed in the chassis.
Do not ship or store this product near strong electromagnetic, electrostatic, magnetic, or
radioactive fields.
Do not disassemble the chassis.
Selecting a Location
The 7280 controller, like other network and computing devices, requires the following “electronic-
friendly” environment:
Reliable power
Verify that your electrical outlet is compatible with the 7280 controller power supply.
Cool, non-condensing ventilation
For proper operation, the 7280 controller requires an environment with an ambient air
temperature between 0º C and 40º C (32º F and 104º F). Humidity must be kept at non-condensing
levels, between 10% and 90%.
Where a large number of electrical devices are working in the same area, additional air
conditioning or air circulation equipment may be required.
Ample space
For proper air circulation, leave at least 10 cm (4 inches) clearance all around the chassis.
Leave additional space in front and rear side of the chassis to access power cords, network cables,
and indicator LEDs.
Limited electromagnetic interference
For best operation, keep the 7280 controller and all cords and cables at least 0.7 meters (2 feet)
from fluorescent lighting fixtures, and 2 meters (6 feet) from photocopiers, radio transmitters,
electric generators, and other sources of strong electromagnetic interference.
Rack Mounting- Standard
This mounting option allows mounting the 7280 controller in a two-post 19-inch Telco rack.
Required Tools and Equipment
The following tools and equipment are required for installing a 7280 controller:
Mounting Bracket (x2) (included in the kit): Do not use for table or shelf installation
Screws for mounting bracket (x8): M4 x 8 mm Phillips Flat Head Screws (included in the kit)
Screws for system rack mount (x4): M6 x 15 mm Phillips Pan Head Screws (included in the kit)
Each 7280 controller should have its own mounting equipment. Do not place other networking equipment
directly on top of a mounted 7280 controller. Failure to do so can damage the device.
