How to get the MAC address for an EIU
Nortel is responsible for assigning blocks of MAC addresses to its customers.
To obtain MAC addresses, contact your Nortel Engineering support group by
using the internal Nortel email address, MAC ADDRESS2. This process is
documented in ECM620 and is provisioned by Nortel personnel.
CAUTION
Possible loss of service
Do not assign an arbitrary MAC address to either EIUs or
other SuperNode equipment. Duplicate MAC addresses can
cause protocol conflicts at the Open Systems Interconnect
(OSI) data link or equivalent layer, making equipment
unaccessible to the network.
