Problem Solution
Unable to ping the NMC
If the NMC’s Status LED is green, try to ping another node on the same
network segment as the NMC. If that fails, it is not a problem with the NMC.
If the Status LED is not green, or if the ping test succeeds, perform the
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.
Cannot allocate the
communications port through a
terminal program
Before you can use a terminal program to configure the NMC, you must shut
down any application, service, or program using the communications port.
Cannot access the command
line interface through a serial
connection
Make sure that you did not change the baud rate. Try 2400, 9600, 19200, or
38400.
Cannot access the command
line interface remotely
• Make sure you are using the correct access method, Telnet or Secure SHell
(SSH). An Administrator can enable these access methods. By default,
Telnet is enabled. Enabling SSH automatically disables Telnet.
For SSH, the NMC may be creating a host key. The NMC can take up to one
minute to create the host key, and SSH is inaccessible for that time.
Cannot access the user
interface
• Verify that HTTP or HTTPS access is enabled.
• Make sure you are specifying the correct URL — one that is consistent with
the security system used by the NMC. SSL requires https, not http, at the
beginning of the URL.
• Verify that you can ping the NMC.
• Verify that you are using a Web browser supported for the NMC. See
“Supported Web browsers” on page 28.
• If the NMC has just restarted and SSL security is being set up, the NMC
may be generating a server certificate. The NMC can take up to one minute
to create this certificate, and the SSL server is not available during that time.
