Connectors |
 |
The connectors on
La 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 SC or LC connectors. The
1000Base-T port is compatible with the IEEE 802.3ab standard and
uses an RJ-45 connector.
Cabling |
|
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. Table
B-1 summarizes the cabling requirements
for the 1000Base-SX and 1000Base-T products.

Cable Description
(850nm short-wave
laser) | Modal Bandwidth | Operating Distance |
|---|
| 62.5 micron multimode fiber (MMF)
cable | 160 (MHz * km) | 2 to 220 meters (6.6 to 722 ft) |
| 200 (MHz * km) | 2 to 275 meters (6.6 to 902 ft) |
| 50 micron multimode fiber (MMF)
cable | 400 (MHz * km) | 2 to 500 meters (6.6 to 1640 ft) |
| 500 (MHz * km) | 2 to 550 meters (6.6 to 1804 ft) |
Category 5 or Category 5E unshielded
twisted-pair (UTP) | 100 MHz | Up to 100 meters |
When running 1000Base-T back-to-back at either 10 or 100
Mbit/s, you must use a crossover
cable configuration. At 1000 Mbit/s, you can use either a crossover
or straight-through cable.
