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.
