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 9240 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. Each fan module
can tolerate the failure of a single fan while maintaining a safe operating temperature for the
gateway.
The LED behavior in the fan module is as follows:
Green - Fan module is operational
Amber - Fan module is faulty
Hot Swapping
Hot swapping allows you to replace a failed fan module, making it unnecessary to shut down the
9240 gateway during the replacement procedure.
PSU Slot 0
The 9240 gateway is equipped with a 550W AC power supply, which is an auto-sensing, 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 9240 gateway is shipped with one hot-swappable, field-replaceable, AC power supply in PSU slot
0 and one filler panel in PSU slot 1. The gateway can operate with one or two active power supplies,
depending on the demands of your configuration. The following sections describe features of the
power supply:
Load Sharing
Load sharing occurs when more than one power supply of the same rating is installed in the 9240
gateway and turned on. Load sharing divides the total power load of the gateway among all available
power supplies. Since the power supplies work together, the effective power capacity of the gateway
is increased with each additional power supply.
Redundancy
With power redundancy, the 9240 gateway 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 gateway 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 9240 gateway during the replacement procedure.
The 9240 is not compatible with fan modules from other Aruba hardware platforms.

14 | 9240 Gateway Aruba 9240 Gateway | Installation Guide
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 of the 550W AC power
supply
PSU Slot 1
The 9240 gateway 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13.
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.

1. Insert the coupler end of the AC power cord into the AC power connector on the power supply
module.
