10/100/1000Base-T Twisted Pair Ports
The switches have two 10/100/1000Base-T ports.
Note
The 10/100/1000Base-T ports are paired with the SFP slots to form
combo ports. For information, refer to “Combo 10/100/1000Base-T
Ports and SFP Slots” on page 32.
Speed The ports can operate at 10, 100, or 1000 Mbps. The speeds may be set
manually using the management software or automatically with Auto-
Negotiation (IEEE 802.3u), the default setting.
Note
The ports must be set to Auto-Negotiation to function at 1000 Mbps
and are not compatible with devices that are not IEEE 802.3u
compliant.
Duplex Mode The 10/100/1000Base-T ports twisted pair ports support full-duplex mode.
They do not support half-duplex mode.
Wiring
Configuration
The wiring configuration of a port operating at 10 or 100 Mbps can be MDI
or MDI-X. The wiring configurations of a switch port and a network device
connected with straight-through twisted pair cabling have to be opposite,
such that one device is using MDI and the other MDI-X. For instance, a
switch port has to be set to MDI-X if it is connected to a network device set
to MDI.
You may set the wiring configurations of the ports manually or let the
switch configure them automatically with auto-MDI/MDI-X (IEEE 802.3ab-
compliant). This feature enables the switch to automatically negotiate with
network devices to establish their proper settings.
The MDI and MDI-X settings do not apply when ports are operating at
1000 Mbps.
Maximum
Distance
The ports have a maximum operating distance of 100 meters (328 feet).
Power Over
Ethernet
The 10/100/1000Base-T ports on the switches do not support PoE.
Cable
Requirements
The cable requirements of the ports are given in Table 2 on page 26.
