Appendix B      Port, Cable, and Connector Specifications
  USB Ports
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. 
Note Currently the two USB ports are not enabled on the Supervisor Engine 32, Supervisor Engine 32 PISA, 
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 Figure B-2) is used to connect a Category 3, Category 5, Category 5e, 
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.
CX4 
(XENPAK10GB-CX4 and 
X2-10GB-CX4)
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)
LRM 
(XENPAK-10GB-LRM and 
X2-10GB-LRM)
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.
