Testing connectivity to the LAN
To test the external IP connections for the C-LAN, IP Media Processor, and VAL circuit packs,
you must ping the circuit pack and ping a known computer connected to your network. If
everything is configured correctly, the Result column on the Ping Results screen reads PASS.
If it reads ABORT, verify the IP-address information and check the connectivity, including the
cabling.
To test connectivity to the LAN:
1. Type ping ip-address IPaddress board UUCSS and press Enter, where the
variable IPaddress is the IP address of the circuit pack and UUCSS is the cabinet, and slot
of the circuit pack.
2. Type ping ip-address IPaddress board UUCSS and press Enter, where the
variable IPaddress is the IP address of another computer beyond the gateway and UUCSS
is the cabinet, and slot of the circuit pack.

See the maintenance book for your system for detailed alarm and LED descriptions. If a
maintenance object begins to fail some periodic tests, the server will generate an alarm. The
server identifies three levels of alarms:
● Major Alarms — Failures that cause critical degradation of service and require immediate
attention.
● Minor Alarms — Failures that cause some degradation of service, but do not cause a
critical portion of the configuration to be inoperable. This condition requires action, but its
consequences are not immediate. Problems might be impaired service to a few trunks or
stations or interfering with one feature across the entire configuration.
● Warning Alarms — Failures that cause no significant degradation of service or failures in
equipment external to the configuration. Warning alarms are not reported to the attendant
console or INADS.
Alarms are communicated to users and technicians by entries in the alarm and sys logs and the
lighting of LEDs located on the attendant console, on all circuit packs, and, optionally, on
customer-designated telephones.
