Standard MGX 8220 Cables
Table A-21 lists the various cables that can be ordered directly from Cisco. Cable lengths are specified
as a suffix to the model number. For example 5610-50 indicates a 50-foot cable. Cables are generally
available in standard lengths of 10 feet (3 m), 25 feet (7.6 m), 50 feet (15 m), 75 feet (22.8 m) and
100 feet (30 m). Lengths of 101 feet (30 m) to 600 feet (183 m) are available on a special order.
When a cable is connectorized, the connector gender (male-female) will be indicated as well as the
number of pins. For example, RS-232/M25-M25 indicates a cable terminated with a male DB-25 at both
ends.

The redundancy cables are special Y-cables available from Cisco. These cables are required for
