two Nortel Networks Multiservice Switch

alarm.
Prerequisites
•Follow “Avoiding damage from static electricity” (page 208) to protect
the unit from damage by ESD or from transferring ESD to other
hardware.
Procedure steps
1 Connect the interconnect cable to the Alarm 2 connector on the rear of
each of the shelf assemblies as shown in the figure “Dual alarm shelf
interconnection between two Multiservice Switch 7480s” (page 440).
