Connect and Install Adjacent Components

1. Install the following components:
   1. Either the MPO coupler panel or switch at slot 39 first, if removed for a 24kVA PDU
   2. Rear switch-side rail at slot 39, if removed
   3. Either the MPO coupler panel or switch at slot 40
   4. Rear switch-side rail on slot 40

   See Servicing Ethernet Switches.

2. Install the coupler panel at level 41.

   See Install the RJ-45 Coupler Panel.

3. Install the seismic side:

   ---

   Caution  -  Do not trap switch power cords between the seismic side and the RETMA rail-top hats.

   ---

   ---

   Caution  -  Keep the seismic side and the modular system side panel's grounding cords clear.

   ---

   1. Supporting the seismic side, install the top 4 screws.

      ---

      Caution  -  Before proceeding, verify that the holes line up for the other 26 screws.

      ---

   2. Install the 30 M6 screws that connect the seismic side to the frame in 46 in-lbs.
   3. Install the 24 RETMA screws that connect the seismic side to the RETMA rail-top hats.
   4. Connect the seismic side grounding cord.
   5. Reconnect any ties or straps holding cables to the seismic side.
4. Install the side panel and connect the grounding cords.
5. If you moved the modular system to provide access to the PDU, return the modular system to its former location and secure it.

   See Return the Modular System to Previous Location.

6. Connect any external I/O cables that were disconnected for the service.
7. Connect all PDU power input cords to their inputs.
8. Install the front and rear doors of the modular system cabinet.
9. Carefully check all the components and parts that you handled, to ensure that they are installed and connected correctly.
10. Switch on the main power circuit breakers.

    These are the main power breakers to the room or building outlets that supply power to the PDUs.
