Chapter 10: Cabling the Networking Ports
Cabling Twisted Pair Ports
154
Here are the guidelines to cabling the twisted pair ports on the switch:
The category of twisted pair cable requirements are as follows:
– 10/100Mbps ports: Standard TIA/EIA 568-B-
compliant Category 3 unshielded cabling.
– 1000Mbps ports: Standard TIA/EIA 568-A-
compliant Category 5 or TIA/EIA 568-B-compliant
Enhanced Category 5 (Cat 5e) unshielded cabling.
– 1/2.5/5Gbps ports: Standard TIA/EIA 568-A-
compliant Category 5 or TIA/EIA 568-B-compliant
Enhanced Category 5 (Cat 5e) unshielded cabling.
PoE is enabled by default on the x530DP-28GHXm and x530DP-
52GHXm 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 and higher.
The ports support full-duplex only when operating at 1Gbps and
higher. The ports support half- and full-duplex when operating at
10/100Mbps.
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.
Caution
Do not connect or disconnect copper cables from PoE++ devices
(Class 5, 40W or higher) when the switch is powered on. It might
damage the switch. Before cabling PoE++ devices, do one of the
following:
- Power off the switch, or:
- Disable PoE on the ports with the NO POWER-INLINE ENABLE
command. After cabling the ports, activate it again with the POWER-
INLINE ENABLE command.
