Management Card Access Problems

For problems that are not described here, see the troubleshooting flowcharts on the APC

Network Management Card Utility CD. Click the Troubleshooting link in the CD interface.

If the problem still persists, see “APC Worldwide Customer Support” on page 96.

Problem Solution

Unable to ping the Management

Card

If the Management Card’s Status LED is green, try to ping another node on

the same network segment as the Management Card. If that fails, it is not a

problem with the Management Card. 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.

• Verify all network connections.

• Verify the IP addresses of the Management Card and the NMS.

• If the NMS is on a different physical network (or subnetwork) from the

Management Card, verify the IP address of the default gateway (or

router).

• Verify the number of subnet bits for the Management Card’s subnet mask.

Cannot allocate the

communications port through a

terminal program

Before you can use a terminal program to configure the Management Card,

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 Management Card may be creating a host key. The

Management Card 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 Management Card. SSL requires

https, not http, at the beginning of the URL.

• Verify that you can ping the Management Card.

• Verify that you are using a Web browser supported for the Management

Card. See “Supported Web browsers” on page 28.

• If the Management Card has just restarted and SSL security is being set

up, the Management Card may be generating a server certificate. The

Management Card can take up to one minute to create this certificate, and

the SSL server is not available during that time.
