4.3.2 Adding an NPU1 D
Caution!
Electrostatic Discharge (ESD) may damage the equipment. Always use an
approved ESD wrist strap to avoid damage to components fitted on printed
circuit boards.
Note: When replacing two NPU1 C units configured for Ethernet Switch
Protection, both units must be removed and both positions cleared
before inserting a new NPU1 D.
To minimize downtime when adding two NPU1 D units, insert and configure an
NPU1 D in the primary slot, before inserting an NPU1 D into the secondary slot.
4.3.2.1 Adding an NPU1 D to the Primary Slot
To add an NPU1 D to the primary slot, and move the licenses from the NPU1 C
to the NPU1 D by reusing the RMM from the NPU1 C:
1. Remove the NPU1 D from the ESD-protective packaging.
2. Insert the RMM from the NPU1 C into the RMM holder on the NPU1 D.
