USB Ports

Supervisor Engine 32, Supervisor Engine 32 PISA, Supervisor Engine 720-10GE, and Supervisor
Engine 2T have two USB ports located on front panel. One port is designated for host use and the other
as a device port. A host USB port can be used to plug in devices such as a PC, while device ports can be
used for attaching Flash Memory Key devices.
Currently the two USB ports are not enabled on the Supervisor Engine 32, Supervisor Engine 32 PISA,
Note
and Supervisor Engine 720-10GE. The 5-pin USB port on the Supervisor Engine 2T is enabled. The
second USB connector is not currently enabled.

Copper and Fiber-Optic Connectors

This section describes the types of copper and fiber-optic connectors that are used with the supervisor
engines.

RJ-45 Connector

The RJ-45 connector (see
Category 6, or Category 6a FTP or UTP cable from the modem or terminal to the supervisor engine
console port, or the network to a copper uplink port if the uplink port has a 1000BASE-T copper
transceiver installed in it.

Cabling Guidelines for Transceivers (continued)
Cabling Guideline
The Cisco CX4 transceiver supports link lengths of up to 49.2 feet
(15 m) on CX4 cable. Cisco offers four CX4 cables:
CAB-INF-28G-1= (1 meter cable)
•
CAB-INF-28G-5= (5 meter cable)
•
CAB-INF-28G-10= (10 meter cable)
•
CAB-INF-28G-15= (15 meter cable)
•
The Cisco LRM transceiver supports link lengths of 220 meters on
standard Fiber Distributed Data Interface (FDDI) grade multimode fiber
(MMF). To ensure that specifications are met over FDDI-grade, OM1
and OM2 fibers, the transmitter should be coupled through a
mode-conditioning patch cord. Cisco offers two mode-conditioning
patch cords:
• CAB-GELX-625= —Mode-conditioning patch cable
(62.5 microns) with dual SC connectors.
CAB-MCP50-SC= —Mode-conditioning patch cable (50 microns)
•
with dual SC connectors. No mode-conditioning patch cord is
required for applications over OM3 fiber cable.
