Connectors on LAN cards adhere to appropriate standards agreed
upon by various standards bodies and are widely available. The 1000Base-SX
port is compatible with the IEEE 802.3z standard and uses a single duplex
SC connector. The 1000Base-T port is compatible with the IEEE 802.3ab
standard and uses an RJ-45 connector.
Incorrectly wired or installed cabling is the most common
cause of communications problems for local area networks. HP recommends
that you work with a qualified cable installer for assistance in
your cabling requirements. The following tables summarize cabling
requirements:
Table C-3 Cabling Requirements for 1000Base-SX
Description
(850nm short-wave laser) | Modal Bandwidth | Operating Distance |
|---|
62.5 micron MMF
(multimode
fibre) | 160 (MHz * km) | 2 to 220 meters |
| 200 (MHz * km) | 2 to 275 meters |
50 micron MMF
(multimode
fibre) | 400 (MHz * km) | 2 to 500 meters |
| 500 (MHz * km) | 2 to 550 meters |
Table C-4 Cabling Requirements for 1000Base-T
Description | Bandwidth | Operating Distance |
|---|
Cat 5 or Cat 5E UTP | 100 MHz | Up to 100 meters |
Back-to-Back
Connection |
 |
When running 1000Base-T back-to-back at either 10 or 100 Mbps, you
must use a crossover cable configuration. At 1000 Mbps, you can
use either a crossover or straight-through cable.
