Prerequisites
Procedure steps
241-1501-240 5.2S2
Replace a failed MAC address module in a Passport 15000 to enable a
network to recognize the node and to enable the node to restart. Replace it
only on the instruction of a Nortel Networks support technician.
CAUTION
Risk of equipment damage or service loss
Inserting a replacement MAC address module in a
Passport 15000 can cause equipment damage to a switch.
The modules have no serviceable parts. Cut the seal and
remove the module only if you have been instructed to by
Nortel Networks technical support.
• You must be familiar with "Safety considerations and best practices"
(page 53).
• Contact Nortel Networks technical support to obtain a case number for
removing the MAC address module before cutting the seal or removing
the module. Record the case number on the shelf near the module.
• You need a Passport 15000 MAC address module with PEC NTHR11.
1 At the rear of the switch, locate the MAC address module to be replaced.
See the figure "Location of the MAC address module in a Passport 15000"
(page 824).
2 Cut the seal when instructed by Nortel Networks technical support.
3 Unfasten the large slotted captive slotted screw.
4 Remove the module by pinching the U-shaped handle and pulling straight
away from the switch.
Removing the module does not generate a software or hardware alarm.
This is normal.
5 Put the module aside.
6 Hold the replacement module so that the U-shaped handle is facing you
and the captive screw is at your right.
