All Junos Pulse Gateways are shipped with an AC power supply. Except for the MAG2600,
all power supplies are internal to the chassis. The MAG2600 uses an external brick power
supply.
You can add one additional power supply to the MAG6611. A cover panel is installed in
the optional power supply slot.
When multiple power supplies are present, they share power almost equally in a fully
populated system. Two AC power supplies provide full power redundancy. If one power
supply fails or is removed, the remaining power supply redistributes the electrical load
without interruption. The device reassesses the power required to support its configuration
and issues errors if the available power is insufficient.
Power supplies are installed at the rear of the chassis in slots labeled 0 and 1 for the
MAG6610 and MAG6611.
Each AC power supply weighs approximately 3 lb (1.3 kg) and has an independent 12 A
rated AC appliance inlet on its front. Each inlet requires a dedicated AC power feed. Each
AC power supply has a fan, a bicolor LED on the faceplate that indicates the status of
the power supply, and a colored ejector lever. See
