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.

service, or program using the communications port.
