B Switch Ports and Network Cables Not e This appendix includes switch connector information and network cable information for cables that should be used with the Series 4100gl Switches, including minimum pin-out information and specifications for twisted-pair cables. Incorrectly wired cabling is the most common cause of problems for LAN communications. HP recommends that you work with a qualified LAN cable installer for assistance with your cabling requirements. Switch Ports Twisted Pair ■ The RJ-45 ports on the 10/100-TX gl Module, the 100/1000-T gl Module, and the on the 100/1000-T Transceiver accept 100-ohm differ ential unshielded and shielded twisted-pair cable with RJ-45 connectors as described on the next page. Fiber-Optic ■ The SC-type connector port on the 100Base-FX Transceiver transmits at 1300 nm wavelength, and accepts the multimode fiber-optic cables for 100Base-FX described on page B-3. ■ The SC-type connector port on the Gigabit-SX Transceiver and the LCtype connector port on the Gigabit-SX LC mini-GBIC Transceiver transmit at 850 nm wavelength, and accept the low metal content, multimode fiber-optic cables for Gigabit-SX described on page B-3. ■ The SC-type connector port on the Gigabit-LX Transceiver and the LCtype connector port on the Gigabit-LX LC mini-GBIC Transceiver transmit at 1300 nm wavelength, and accept the low metal content, single mode or multimode fiber-optic cables for Gigabit-LX described on page B-3.

communications. HP recommends that you work with a qualified LAN cable
installer for assistance with your cabling requirements.
Switch Ports
Twisted Pair
■
The RJ-45 ports on the
10/100-TX gl Module
, the
100/1000-T gl
Module
, and the on the
100/1000-T Transceiver
accept 100-ohm differ
ential unshielded and shielded twisted-pair cable with RJ-45 connectors
as described on the next page.
Fiber-Optic
■
The SC-type connector port on the
100Base-FX Transceiver
transmits
at 1300 nm wavelength, and accepts the multimode fiber-optic cables for
100Base-FX described on
page B-3
.
■
The SC-type connector port on the
Gigabit-SX Transceiver
and the LC-
type connector port on the
Gigabit-SX LC mini-GBIC Transceiver
transmit at 850 nm wavelength, and accept the low metal content, multi-
mode fiber-optic cables for Gigabit-SX described on
page B-3
.
■
The SC-type connector port on the
Gigabit-LX Transceiver
and the LC-
type connector port on the
Gigabit-LX LC mini-GBIC Transceiver
transmit at 1300 nm wavelength, and accept the low metal content, single
mode or multimode fiber-optic cables for Gigabit-LX described on
page B-3
