DESCRIPTION
The MX2800 Power Supply Unit (PSU) is a plug-in unit for the MX2800 chassis that
provides the necessary voltages required to operate the MX2800 and accessories such as
the fan faceplate. The DC version is P/N 1202289L2 and the AC version is P/N
1202289L1. With two cards installed, the MX2800 can recover from power supply unit or
power source failure, depending on configuration. There are three possible
configurations and modes of operation.
Non-Redundant Power Mode
This mode offers no backup protection, but only requires one source of power and one
PSU.
Power Supply Recovery Mode
This mode offers backup protection in the event of power supply card failure. This
configuration uses a primary and a backup PSU, but only utilizes one source of power.
In this mode, the MX2800 can continue operation in the event of a power supply unit
failure, without interrupting service.
Power Supply and Source Recovery Mode
This mode offers a backup system for both card and source failure. In this mode, two
power supply units are installed and are connected to two individual power sources.
This allows the MX2800 to handle any combination of power source or power supply
failure. The MX2800 is able to internally re-route the power source if a power supply
card and the opposite power source fail.
Features of this unit include:
■Receives unregulated power input
■Faceplate status LEDs
■Provision free plug-and-play
■Hot-swappable
■Meets the requirements for NEBS Level 3
■
Accessory plug for fan faceplate

to the guide grooves in the designated PSU slot. Insert into chassis until the
edge connector seats firmly into the backplane. Lock the unit in place by
pushing in on the locking lever.
Verify that PWR (power) LED is active.
LED DESCRIPTIONS
The MX2800 PSU has LED status indicators. The LEDs provided are PWR (power)
and CHK (check). The power LED is active when the unit is on and receiving full
power. The check LED is active when the power supply is failing or is providing
low power and needs to be checked.
