To restart communication between the Nortel SNAS 4050 and a network access

When you first add a network access device to the Nortel SNAS 4050 domain, the
switch is disabled by default. Do not enable the switch until you have completed
configuring it. In particular, do not enable the switch until you have mapped the
VLANs (see “Mapping the VLANs using the SREM” on page 96) and exchanged
the necessary SSH keys (see “Managing SSH keys using the SREM” on
page 102).
Note: If the switch is not going to be used in the Nortel SNA network,
Nortel recommends deleting the switch from the Nortel SNAS 4050
domain, rather than just disabling it.
