Problem:
A LINK/ACT LED is off for a Ethernet copper port that is
connected to an active network device.
Solutions:
The port is unable to establish a link to a network device.
Try the following:
Verify that the network device connected to the Ethernet copper
port is powered on and is operating properly.
Verify the port is connected to the correct Ethernet copper cable.
Problem:
The LINK/ACT LED is off for an SFP transceiver that is
connected to an active network device.
Solutions:
The fiber optic port on the transceiver is unable to
establish a link to a network device. Try the following:
Verify that the fiber optic cable is securely connected to the port
on the transceiver and to the port on the remote network device.
Check that the transceiver is fully inserted in the slot.
Problem:
A port is not supplying power to a PoE device.
Solutions:
Try the following:
Check the port’s PoE LED. Refer to “Ethernet Copper Port LEDs”
on page 17. If the LED is flashing amber, the switch cannot
support additional PoE devices device because it is already
providing its maximum power to other devices. Refer to “PoE+
Review the powered device’s documentation to confirm that the
device supports Mode A (MDI-x) of the IEEE 802.3at standard
and that it uses pins 1, 2, 3, and 6 on the RJ-45 port to receive
power.
Check that the device’s power requirements do not exceed
25.5W by reviewing its documentation or data sheet.
If the device is connected to the GS950/52PS V2 Switch, check
that is connected to a port in the range of 1 to 24. Ports 25 to 48
do not support PoE.
