CAUTION:
CAUTION: When adding or replacing any hardware and associated cables and adapters, be
sure to ground yourself against electrostatic discharge (ESD) by wearing a
grounded wrist strap. Failure to follow ESD procedures can result in system
damage or service disruption.
To replace the existing I/O cables:
1. For the G600 Media Gateway, you must remove the fan assembly to access the cables.
Loosen the thumb screws on the fan assembly and pull it straight out as shown in G600
Media Gateway fan assembly removal on page 857. Leave the fan assembly off until all the
wires are installed.
2. Note the orientation of the existing 10 cables. The existing I/O cables may be white and red
or multicolored. They are not twisted.
3. Remove the nontwisted pair of existing I/O cables from the backplane and the connector
panel slots.
4. In their place install the 10 tight-twisted pair I/O cables onto the backplane, according to the
proper orientation shown in Proper orientation for the twisted pair I/O cables
on page 857.
Observe the white outline printed on the backplane for the location of each connector.
5. When viewed from the "wiring" side of the twin connectors (that is, while plugging them into
the backplane) and with the connectors oriented properly for plug-in, they should look like
Proper orientation for the twisted pair I/O cables
on page 857.
The circled pin locations are “No-Connects”; that is, they have no wires in them. At the top
there is an orange-black pair on the right and a violet-brown pair on the left.
The 50-position metal shell D connectors should be installed into the connector panel with
the longer side of the D (pins 1–25) toward the right when viewed from the rear of the media
gateway.
6. For the G600 Media Gateway, replace the fan unit if no other media gateways are to be
installed. If you are adding more media gateways to the rack, leave the fan units off until all
of the TDM cables are installed.
