Replacing the MAC address module in a Passport 20000
Replace a MAC address module in a Passport 20000 to enable a network to
recognize the node and to enable the node to restart.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You need a Passport 20000 MAC address module with PEC NTPN11.
Procedure steps
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 20000”
(page 826)
2 Unfasten the large slotted captive screws.
3 Remove the module by pinching a captive screw in each hand, and pulling
straight out of the backplane using equal force on each screw.
Removing the module does not generate a software or hardware alarm.
This is normal.
4 Put the module aside.
5 Hold the replacement module so that the label reads upright and the
arrows point upwards.
6 Align the module with the vacant opening and then align the connector on
the module with the connector at the rear of the opening and with the 2
guide pins inside the module cavity.
7 Gently push the module straight in.
8 Align and fasten the screws. Tighten until snug plus a 1/5 turn. Ensure
that you do not strip the threads or hole because the module cannot seat
properly.
9 Contact your software operator of the switch to begin re-configuring the
software.
10 Verify with the software operator that the re-configuration was successful
and that the Passport 20000 reboots.
