Step 9 If you use redundant power leads, terminate the return 2 lead to the positive RET2 terminal on the ONS 15454.
Terminate the negative 2 lead to the negative BAT2 terminal on the ONS 15454. Use oxidation-preventative
grease to keep connections noncorrosive.
The configured ONS 15454 shelf can work with a single power line since the ONS 15454 power
configuration offers redundancy. When using the 15454-FTA3 fan-tray, if the ONS15454 shelf is
powered by a single power line, the BAT-FAIL alarm appears, the fans run at a maximum speed,
and the system does not comply with NEBS GR-63 Issue 3 and GR-1089 Issue 4 and 5 requirements.
In order to meet the above mentioned NEBS requirements, the ONS 15454 shelf must be powered
by both the DC power lines. Note
Step 10
Route the cables out below the power terminals using the plastic cable clamp, as shown in Figure 40: Cisco
ONS 15454 Power Terminals, on page 73 .
Step 11 Connect the return cables to earth ground at power supply side.
Step 12 Return to your originating procedure (NTP).

Procedure
Step 1
Using a voltmeter, verify the office battery and ground at the following points on the fuse and alarm panel:
a) To verify the power, place the black test lead of the voltmeter to the frame ground. Place the red test lead
on the A-side connection and verify that it is between –40.5 VDC and –57 VDC. Place the red test lead
on the B-side connection and verify that it is between –40.5 VDC and –57 VDC.
