Unable to ping the
Management Card
Is the Management Card’s Status
LED
green,
indicating it is up and running its
SNMP
agent on the
network? If yes, try to ping another node on the same
network segment as the Management Card. If that
fails, it is not a Management Card problem. If the
Status
LED
is not green, or if the ping test succeeds,
perform the following checks:
• Verify that the Management Card is properly seated
in the UPS
or expansion chassis.
• Verify all network connections.
•Verify IP
addresses of the Management Card and
the
NMS
, and make sure both are on the same
network or subnetwork.
• Verify the default gateway (or router)
IP
address if
the
NMS
is on a different physical network (or
subnetwork) from the Management Card.
• Verify the number of subnet bits for the
Management Card’s subnet mask.
