To remove Main PS (1):

NOTE: The mounting of a Cherokee/Mitra

PS and Lambda PS are the same. The PS

connectors are in different locations.

NOTE: When the system is in standby, the

Lambda PS will be warm. This is normal for

a Lambda PS.

Disconnect the Mains PS Cable and all

cables (2) - AC Output to Peripherals,

Printer, Power to BEP and USB on top of

the Main PS.

Remove the three screws (3) that secure

the Main PS using a 5 mm Allen wrench.

Ease the Main PS away from the fang

bracket (4).

Pull/slide the entire Main PS backwards

until the connectors to the Card Cage/

Backplane are unseated.

NOTE: If the 4D MC option is installed,

proceed to Step 2. If not proceed to Step 3.

NOTE: If the Shear Wave option is

installed, the cable that supplies voltage to

the Capacitor Pack is located behind the

BEP Power Cable and the Printer Cable

may not be present.
