Troubleshooting

Management Card

Access problems (Battery Management System

Management Card)

Problem Solution

Unable to ping the

Management Card

Is the Management Card’s Status LED (on the front panel of the

master controller) green, indicating it is running its SNMP agent

on the network? If yes, try to ping another node on the same

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

a Management Card problem.

If the Status LED is not green, or if the ping test of another node

succeeds, perform the following checks:

• Verify all network connections.

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

• Verify the default gateway (or router) IP address if the NMS is

on a different physical network (or subnetwork) from the

Management Card.

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

subnet mask.

The terminal

program cannot

allocate the

communications

port when you try to

configure the

Battery

Management

System

Before you can use a terminal to configure the Battery

Management System, you must shut down any application,

service, or program using the communications port.
