Cabling and Specifications
Step 2 Attach the line card cable-management bracket to the line card as follows:
a. Position the cable-management bracket over the front of the line card faceplate.
b. Insert and tighten the captive screw(s) to secure the bracket to the line card.
c. Starting with the bottom port on the line card, connect each interface cable to the intended port.
Step 3 For multiport line card cable-management brackets, carefully wrap the cables with the supplied Velcro
strap. (See Figure 32.)
For single-port line card cable-management brackets, carefully press the interface cable onto the cable
clip. (See Figure 33.) Avoid any kinks or sharp bends in the cable.
For information on disconnecting and connecting interface cables, see the “Removing and Installing
Fiber-Optic Interface Cables” section on page 52.

Fast Ethernet Interface
The term Ethernet is commonly used for all carrier sense, multiple access/collision detection
(CSMA/CD) local-area networks (LANs) that conform to Ethernet specifications, including Fast
Ethernet defined by IEEE 802.3u.
IEEE 802.3u specifies the following different physical layers for 100BASE-T:
• 100BASE-TX—100BASE-T, half- and full-duplex over Category 5 unshielded twisted-pair (UTP),
Electronics Industry Association/Telecommunications Industry Association
[EIA/TIA]–568-compliant cable.
Note The 8-Port Fast Ethernet line card provides an RJ-45 connector that follows the
Media-Dependent Interface (MDI) port wiring standard, as opposed to the
Media-Dependent Interface-crossed (MDI-X) wiring scheme found on many hubs and
repeaters.
