100/1000Mbps
Twisted Pair
Ports
Ports 25R and 26R on the AT-x310-26FT and AT-x310-26FP Switches
and ports 49R and 50R on the AT-x310-50FT and AT-x310-50FP
‘Switches are 10/100/1000Base-T ports. The ports have two LEDs that
display link, activity and duplex mode information. The LEDs are shown in
Figure 10 on page 39.
Note
The 10/100/1000Base-T ports are paired with the SFP slots to form
combo ports. For information, “Combo 10/100/1000Base-T Ports
and SFP Slots” on page 32.
Note
The ports support full-duplex mode, but not half-duplex mode.
PoE Green The switch is detecting a powered device
(PD) on the port and is delivering power to
it.
Solid Amber The switch has shutdown PoE+ on the port
because of a fault condition.
Flashing
Amber The switch is detecting a PD on the port but
is not delivering power to it because the
maximum power budget has been reached.
Off This LED state can result from the following
conditions:
 The port is not connected to a PD.
 The PD is powered off.
 The port is disabled in the
management software.
 PoE is disabled on the port.
 The LEDs on the Ethernet line cards
are turned off. To turn on the LEDs,
