Solution:If the NMC’s Status LED is green, try to ping another node on the samenetwork segment as the NMC. If that does not work, it is not a problem with
the NMC. If the Status LED is not green, or if the ping test succeeds, performthe following checks:
• Verify that the NMC is properly seated in the UPS.
• Verify all network connections.
• Verify the IP addresses of the NMC and the NMS.
• If the NMS is on a different physical network (or subnetwork) from the NMC, verify the IP address of the default gateway (or router).
• Verify the number of subnet bits for the NMC’s subnet mask.
