If you are using a 100-A fuse panel, insert a 30-A fuse into the fuse position according to site
practice.
To verify the A-side of the shelf, place the black lead of the voltmeter to the frame ground. Place the
red test lead to the BAT1 (A-side battery connection) red cable. Verify that it reads between
–40.5 VDC and –57 VDC. Then place the red test lead of the voltmeter to the RET1 (A-side return
ground) black cable and verify that no voltage is present.
Note The voltages –40.5 VDC and –57 VDC are, respectively, the minimum and maximum
voltages required to power the chassis.
To verify the B-side of the shelf, place the black test lead of the voltmeter to the frame ground. Place
the red test lead to the BAT2 (B-side battery connection) red cable. Verify that it reads between
–40.5 VDC and –57 VDC. Then place the red test lead of the voltmeter to the RET2 (B-side return
ground) black cable and verify that no voltage is present.
This procedure installs the fan-tray assembly.
