Rack PDU Access Problems

For problems that persist or are not described here, see the back cover of this manual.

Problem

Solution

 

 

Unable to ping the Rack PDU

If the Rack PDU’s 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 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.

 

 

Cannot allocate the

interface remotely

An Administrator can enable these access methods. By default, Telnet is enabled.

 

Enabling SSH automatically disables Telnet.

 

• For SSH, the Rack PDU may be creating a host key. The Rack PDU can take up to

 

one minute to create the host key, and SSH is inaccessible for that time.

 

 

Cannot access the Web 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 Rack PDU. SSL requires https, not http, at the

 

beginning of the URL.

 

• Verify that you can ping the Rack PDU.

 

• Verify that you are using a Web browser supported for the Rack PDU. See

 

“Supported Web Browsers” on page 40.

 

• If the Rack PDU has just restarted and SSL security is being set up, the Rack PDU

 

may be generating a server certificate. The Rack PDU can take up to one minute to

 

create this certificate, and the SSL server is not available during that time.

 

 

Cannot communicate using

• If you are having communications problems with Network Port Sharing, check

Network Port Sharing

that the total length of network cable between up to four units is not more than 10

 

meters.

 

• If you are having communications problems with Network Port Sharing, check

 

that a terminator is installed at both ends of up to four units that can be grouped

 

together.

 

• If you are using Network Port Sharing and do not see one or more of the units in

 

the group, check that all units in the group are using the same firmware revision.

 

You can download appropriate firmware revisions from the APC website.
