Speed or duplex mismatch
A duplex mismatch on the WLAN can cause the WLAN IP Telephony
Manager 2245 to not operate properly. Double-check WLAN connections
and interfaces to ensure that they are all configured as full-duplex.
In rare instances, the message Speed or Duplex mismatch error can occur
during the bootup sequence of the IP Telephony Manager 2245.
If this situation occurs, verify all devices connected to the WLAN IP
Telephony Manager 2245 are configured correctly and no duplex mismatch
is found. If all configurations are correct, reboot the IP Telephony Manager
2245. The error message must be cleared.
Nortel recommends that you
•
do not configure the Ethenet Link, on the SVP-II Configuration screen,
to auto-negotiate.
•
use either 100/full or 10/full, as is appropriate for the network.
•
configure the ethernet switch port to match the 2245 Ethernet Link.
