Installing Expansion Sub-Modules

Caution: The expansion sub-modules contain components sensitive to electrostatic
discharge. Do not touch the circuit board unless instructed to do so.

Installing the Expansion Sub-Module into the P333R-LB

To install the expansion sub-module into the P333R-LB:
1 Remove the blanking plate or other sub-module (if installed).
2 Insert the sub-module gently into the slot, ensuring that the Printed Circuit
Board (PCB) is aligned with the guide rails. The PCB, not the metal base plate,
fits into the guide rail.
3 Press the sub-module in firmly until it is completely inserted into the P333R-LB.
4 Gently turn the two screws on the front panel of the expansion sub-module
until they are secure.

Removing an Existing Expansion Sub-Module

To remove an existing expansion sub-module:
1 Loosen the two screws on the front panel of the expansion sub-module.
2 Grasp the two knobs one near each side of the front panel, and pull gently but
firmly towards yourself.
3 Insert another expansion sub-module or the blanking plate.
Note: If an expansion sub-module is removed from the stack with the power supply
on, all configuration definitions on expansion sub-modules are lost. To remove an
expansion sub-module and save configuration definitions:
1 Turn off the power supply.
2 Remove an expansion sub-module.
3 Insert another expansion sub-module.
4 Turn on the power supply.
Note: The P333R-LB switch must not be operated with the expansion slot open. The
expansion sub-module slot should be covered with the supplied blanking plate if
necessary.
