Tip Problem Solution
5 The network port for which the
LED is blinking has experienced
a self-test or initialization
failure.
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.
6 The network connection is not
working properly.
Try the following procedures:
n
For the indicated port, verify both ends of the
cabling, at the switch and the connected device, are
connected properly.
n
Verify that the connected device and switch are
both powered on and operating correctly.
n
Verify that you have used the correct cable type for
the connection:
o
For twisted-pair connections to the fixed 10/100
or 10/100/1000 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
10/100/1000-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.
o
For fiber-optic connections, verify that the
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.
n
For 1000Base-T connections, verify that the
network cabling complies with the IEEE 802.3ab
standard. Install the cable according to the
ANSI/TIA/EIA-568-A-5 specifications. Ensure that
cable testing complies with the stated limitations
