HPE Aruba Networking CX 6300 Switch Series | Installation and Getting Started Guide
Problem
One or more of the switch
cooling fans may have failed.
The network port for which the
LED is blinking has experienced
a self-test or initialization
failure.
The network connection is not
working properly.
Solution
Try disconnecting power from the switch and wait a
few moments. Then reconnect the power to the switch
and check the LEDs again. If the error indication
reoccurs, one or more of the fans has failed. Call your
Hewlett Packard Enterprise authorized network
reseller.
Try power cycling the switch. If the fault indication
reoccurs, the switch port may have failed. Call your
Hewlett Packard Enterprise authorized network
reseller.
If the port is a pluggable SFP/SFP+ unit, verify it is a
pluggable supported by the switch. An unsupported
pluggable will be identified with this fault condition.
Caution: Use only supported genuine Hewlett Packard
Enterprise transceivers with your switch.
To verify that the port has failed, try removing and
reinstalling the SFP/SFP+. You can do that without
having to power off the switch. If the port fault
indication reoccurs, you will have to replace the
SFP/SFP+ unit.
Try the following procedures:
For the indicated port, verify both ends of the
n
cabling, at the switch and the connected device, are
connected properly.
Verify that the connected device and switch are
n
both powered on and operating correctly.
Verify that you have used the correct cable type for
n
the connection:
For twisted-pair connections to the fixed Base-T
o
ports, if the port is configured to "Auto" (auto
negotiate), either straight-through or crossover
cables can be used. This allowance is because of
the switch's "Aruba Auto-MDIX" feature and the
Auto MDI/MDI-X feature of the Base-T port.
NOTE: If the switch port configuration is changed
to one of the fixed configuration options (for
example, 100 Mbps/Full Duplex), then the port
operates as MDI-X only and you must use the
correct type of cable for the connection. In
general, for connecting an end node (MDI port)
to the switch, use straight-through cable; for
connecting to MDI-X ports on hubs, other
switches, and routers, use crossover cable.
For fiber-optic connections, verify that the
o
transmit port on the switch is connected to the
receive port on the connected device, and the
switch receive port is connected to the transmit
port on the connected device.
For Base-T connections, verify that the network
