assemblies (15454-SA-ANSI, 800-19857). It includes a pin that does not allow it to be installed in
ONS 15454 shelf assemblies released earlier than ONS 15454 Release 3.1 (15454-SA-NEBS3E,
15454-SA-NEBS3, and 15454-SA-R1, P/N 800-0714915454). Installing the 15454-FTA3 in a
noncompliant shelf assembly might result in failure of the alarm interface panel (AIP), which in turn,
will result in power loss to the fan-tray assembly.

If you are using a 80-A fuse panel, insert a 20-A fuse into the fuse position according to site practice.
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
–42 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 –42 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
–42 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.
