Cabling Requirements of Ethernet PCI Adapters
The following sections describe the cabling requirements of the following Ethernet PCI
adapters:
•

N O T E
Label each cable that you attach to a PCI adapter, noting
the host name, I/O element number, PCI slot number, and
port number (if applicable) to which the cable connector
attaches.
Cabling U575 and Embedded Ethernet PCI Adapters
The U575 PCI adapter and embedded Ethernet PCI adapters require
customer-supplied, Unshielded Twisted Pair (UTP) Ethernet cables with RJ-45
connectors (see
Figure 2-2 ). For each port, supply a 24 AWG, 4-pair, UTP
EIA/TIA-Verified, Category-3 or Category-5 wire cable, with RJ-45 modular connectors
terminated with pair-wiring adhering to the EIA/TIA 568-A or EIA/TIA 568-B standard.
The speed of the network determines the grade of UTP cable that you can use:
•
10 Mbps requires UTP Category-3 or Category-5 Data-Grade cable.
•
100 Mbps and 1000 Mbps require UTP Category-5 Data-Grade cable. Use of
Category-3 Data-Grade cable for 100 Mbps or 1000 Mbps would cause data loss.
For 1000 Mbps, use Category-5e Data-Grade cable.
To connect to an Ethernet hub or switch, use a straight-through cable, not a
crossed-pair (1-3, 2-6) cable or an Ethernet crossover cable. The maximum distance
between the PCI adapter and an Ethernet hub or a switch is 328 ft (100m).
