NTP-G291 Attach Wires to Timing, LAN, and Craft Pin Connections in ONS 15454 M2

a) 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 -48V (A-side battery connection) red cable. Verify that it reads between –40.5 VDC and
–57.6 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
b) 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 -48V (B-side battery connection) red cable. Verify that it reads between –40.5 VDC
and –57.6 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.

Caution Always use the supplied Electrostatic Discharge (ESD) wristband when working with a powered ONS 15454
M2. For detailed instructions on how to wear the ESD wristband, refer to the
Grounding Guide for Cisco CPT and Cisco ONS Platforms
Note
To route the copper cables from the SFPs or RJ-45 ports in a ONS 15454 M2 shelf, removal of the shelf door
is mandatory.
Note
The minimum distance between the fiber LC connector and the bulk attenuator must be at least 50 cm. This
is the minimum distance required to place the bulk attenuator outside the shelf from any port of a card.

The voltages –40.5 VDC and –57.6 VDC are, respectively, the minimum and maximum voltages
required to power the chassis.
To view the shelf voltage and temperature, refer to the
Temperature, on page 76.
