Replacing I/O cables
On older MCC, SCC, and G600 cabinets you must replace the existing I/O cables (WP-90753,
LI), which connect the backplane to the rear connector panel, with twisted pair I/O cables.
The existing I/O cables have straight, not twisted, wires. They may be mostly white with two red,
or multi-colored. If the cables have multi-colored, tightly twisted wires, no replacement is
necessary.
To order the DEFINITY kit with twisted pair I/O cables, use comcode 700234032.

CAUTION:
CAUTION: Turn off power to the carrier or media gateway being serviced. Failure to turn off
the power can result in electric shock.
