Chapter 9: Cabling the Networking Ports

Cabling Twisted Pair Ports
Here are the guidelines to cabling the twisted pair ports on the switches:
Minimum twisted pair cable requirements are as follows:
– 10/100Mbps ports: Standard TIA/EIA 568-B-compliant
Category 3 unshielded cabling
– 1Gbps ports: Standard TIA/EIA 568-A-compliant Category 5
or TIA/EIA 568-B-compliant Enhanced Category 5 (Cat 5e)
– 2.5/5Gbps ports: Standard TIA/EIA 568-A-compliant Category
6 or TIA/EIA 568-B-compliant Category 6A (Cat 6A)
unshielded cabling
PoE is enabled by default on the x530L-10GHXm, x530L-
18GHXm, x530L-28GPX and x530L-52GPX switch ports.
The connectors on the cables must fit snugly into the ports, and the
tabs must lock the connectors into place.
The default speed setting for the ports is Auto-Negotiation. This
setting is appropriate for ports connected to network devices that
also support Auto-Negotiation.
The ports must be set to the default setting of Auto-Negotiation to
operate at 1Gbps.
The twisted pair ports can operate in either half- or full-duplex
mode when operating at 10/100Mbps. However, if any of the
twisted pair ports operate at 1Gbps or higher, then the duplex
mode is always full-duplex.
Do not attach cables to ports of static or Link Aggregation Control
Protocol (LACP) port trunks until after you configure the trunks on
the switch. Otherwise, the ports will form network loops that can
adversely affect network performance.
