Cabling Copper Ports
Here are the guidelines to cabling the copper ports:
The minimum copper cable requirements are as follows:
– 10/100Mbps ports: Standard TIA/EIA 568-B-compliant
Category 3 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.
– 10Gbps ports: Standard TIA/EIA 568-C-compliant Category 6a
unshielded cabling.
The cable specifications for the 10/100/1000Base-T copper ports
are listed in “Cable Requirements” on page 34.
The connectors on the cables should fit snugly into the ports, and
the tabs should lock the connectors into place.
The default setting for the wiring configurations of the ports is auto-
MDI/MDI-X. The default setting is appropriate for switch ports that
are connected to 10/100Base-TX network devices that also
support auto-MDI/MDI-X.
The default auto-MDI/MDI-X setting is not appropriate for switch
ports that are connected to 10/100Base-TX network devices that
do not support auto-MDI/MDI-X and have a fixed wiring
configuration. For switch ports connected to those types of network
devices, you should disable auto-MDI/MDI-X and set the wiring
configurations manually.
The appropriate MDI/MDI-X setting for a switch port connected to a
10/100Base-TX network device with a fixed wiring configuration
depends on the setting of the network device and whether the
switch and network device are connected with straight-through or
crossover cable. If you are using straight-through twisted pair
cable, the wiring configurations of a port on the switch and a port
on a network device must be opposite each other, such that one
port uses MDI and the other MDI-X. For example, if a network
device has a fixed wiring configuration of MDI, you must disable
auto-MDI/MDI-X on the corresponding switch port and manually
set it to MDI-X. If you are using crossover twisted pair cable, the
wiring configurations of a port on the switch and a port on a
network device must be the same.
PoE is enabled by default on the x530-10GHXm, x530-18GHXm,
x530-28GPXm and x530-52GPXm switch ports.
The connectors on the cables must fit snugly into the ports, and the
tabs must lock the connectors into place.
