Battery Replacement Procedure for T3 and T3+ pcu batteries

--------------------------------------

PROCEDURES:

1.) Replacing the PCU battery:

a) Lay the PCU upside down on a work area.

b) Remove 4 Phillips screws (on top and right side) from the battery plate.

CAUTION - BE CAREFUL NOT TO DROP ANY SCREWS INSIDE THE PCU.

THERE ARE HIGH POWERED COMPONENTS INSIDE THE PCU

THAT CAN BE SHORTED. IF YOU DROP A SCREW INSIDE

THE PCU MAKE SURE YOU RETRIVE IT BEFORE CONTINUING.

c) With the fan faceplate facing you, lift the right side of the

battery slightly and gently pull the battery assembly to the

right until the battery connector (on left) is unseated.

d) Install new battery assembly, assuring connector is fully inserted.

NOTE - IF ANY PIN IS BROKEN OR BENT, THE POWER COOLING UNIT MUST

BE REPLACED.

e) Secure the 4 Phillips screws to battery plate.

f) Insert the pcu back into the pcu slot.

CAUTION - BE CAREFUL NOT TO DROP ANY SCREWS INSIDE THE PCU. THERE ARE HIGH

POWERED COMPONENTS INSIDE THE PCU THAT CAN BE SHORTED. IF YOU DROP A

SCREW INSIDE THE PCU THEN MAKE SURE YOU RETRIVE IT BEFORE CONTINUING.

2.) From the T3 CLI type ".bat -n u(x)pcu(y)", where u(x) is the unit # and

pcu(y) is the PCU location # of the just installed PCU. This will zero out

the 'Battery Warranty Date' field and set the 'Battery Install Week' based

on the T3 date setting. It also will zero out the 'Battery Internal Flag'

if it was set to 1, indicating low battery.

3.) Type ".id write busage u(x)pcu(y) 0 ". This will calculate the 'Battery

Warranty Date' and 'Battery Life Used'. This can be verified by typing

"id read u(x)pcu(y)".

4) Repeat steps 1-3 for the other pcu in the system if it is also expired.

5.) Dispose of the battery in accordance with local laws.
