Passport 15000, 20000 Hardware Installation, Maintenance, and Upgrade
A Passport 15000 or 20000 requires input power cables that are installed on
the site up to where the mounting apparatus of the switch will be anchored.
Planning and installing the power cables in readiness for connecting to the
breaker interface panel (BIP) after the NEBS 2000 frame is anchored is
typically done during the site preparation for the installation. The cables that
distribute power from the input feeds at the BIP to hardware parts in the frame
are pre-installed at the time the frame is shipped. The power distribution
cables for a second switch are provided even if the second one is not yet
installed.
Mount the power cables against the NEBS 2000 frame in bundles on different
paths than the signaling cables from the front of the switch. The current from
power cables can interfere with the transmission of signals over coax. Route
power cables at the rear of the frame.
When routing the power cables, keep the battery return (positive) and battery
(negative) cable pairs together. Otherwise, the cables can behave like
antennas that transmit electromagnetic interference (EMI).
See 241-1501-205 Passport 15000, 20000 Site Requirements and
Preparation Guide for information about routing power cables to the
Passport.
Keep FPs that use coax cables on the opposite side of the self from FPs that
use fiber cables. Mixing FP cable types can cause entangled cables, affect
signal quality, and may cause service failure. Keep coax cable clusters
separate from power cables to avoid interference.
Most Passport 15000 or 20000 powered components are hot-swappable,
which means a plug-in card or module can be replaced while it is powered.
No physical damage is caused by the removal or the insertion. The impact of
hot-swapping on traffic is determined by the preparation you are instructed to
do in software according to the part's replacement procedure.
