locked up and is displaying “Mitel

disconnecting it and then recon-

necting it.

Faulty programming. Verify that your number plan,

extension groups, and secondary

number plan are programmed

correctly.

See Modify the extensions and

Faulty phone. Replace the phone with a known

working phone of the same

model to determine if the phone

is faulty.

top drop including patch panel

connections.

tings.

Check the LAN devices (PC NIC

cards, switches, 3100 ICP switch

settings and Ethernet ports all

have the same Ethernet settings

(auto-sensing, 10BaseT or
