Cisco ONS 15454 Installation and Operations Guide, R3.2
January 2005
Chapter 1 Hardware Installation
Power and Ground Installation
The existing ground post is a #10-32 bolt. The nut provided for a field connection is also a #10, with an
integral lock washer. The lug must be a dual-hole type and rated to accept the #6 AWG cable. Two posts
are provided on the Cisco ONS 15454 to accommodate the dual-hole lug. Figure 1-22 shows the location
of the ground posts.

For information about attaching ferrites to power cabling, see the “Ferrite Installation” section on
page 1-61.
Warning
When installing redundant power feeds, do not use aluminum conductors.
Warning
If you use redundant power leads to power the ONS 15454, disconnecting one lead will not remove
power from the node.
Procedure: Install Redundant Power Feeds
Ground only one cable to ground the shelf assembly. Terminate the other end of the ground cable to
ground according to local site practice. The ONS 15454 backplane also has a ground terminal on the
right side of the backplane. Connect a ground terminal for the frame ground (FGND) terminal according
to local site practice.
If the system loses power or both TCC+ cards are reset, you must reset the ONS 15454 clock. After
powering down, the date defaults to January 1, 1970, 00:04:15. To reset the clock, see the “Setting Up
Basic Node Information” section on page 3-2.
Note If you encounter problems with the power supply, refer to the Cisco ONS 15454 Troubleshooting and
Maintenance Guide for possible causes.
Warning
Do not apply power to the ONS 15454 until you complete all installation steps and check the
continuity of the -48V DC and return.
Step 1 Measure and cut the cables as needed to reach the ONS 15454 from the fuse panel. Figure 1-23 shows
the ONS 15454 power terminals.
Step 2 Dress the power and ground cables according to local site practice.
Warning
When installing the ONS 15454, the ground connection must always be made first and
disconnected last.
