Management Card
Management Card access problems
For problems that are not described in the following table, see
SNMP problems. If you still cannot resolve the problem, see
Obtaining service.
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 Management Card
problem.
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 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.
The terminal program
cannot allocate the
communications port
when you try to
configure the
Management Card
Before you can use a terminal to configure the Management
Card, you must shut down any application, service, or program
using the communications port.
