Unable to Ping the IP Address assigned to Rack PDU AP7921B ?

Published date: 12 July 2020

Please follow the procedure to resolve the issue.                                                                                                                                                                                                                                                                         
If the Rack PDU’s Network Status LED is green, try to ping another node on
the same network segment as the Rack PDU. If that fails, it is not a problem
with the Rack PDU. If the Network Status LED is not green, or if the ping
test succeeds, perform the following checks:
• Verify all network connections.
• Verify the IP addresses of the Rack PDU and the NMS.
• If the NMS is on a different physical network (or subnetwork) from the
Rack PDU, verify the IP address of the default gateway (or router).
• Verify the number of subnet bits for the Rack PDU’s subnet mask.
