Removing and replacing the Western Telematic Inc. switch for the TS7650G (Gateway), ProtecTIER V3.4.3

To remove and replace the Western Telematic Inc. (WTI) switch, perform the following steps.

1. Before removing the old WTI switch, issue a poweroff command to the upper ProtecTIER® server Node B.
2. Wait until the upper ProtecTIER Node B is powered off, then issue a poweroff command to the lower ProtecTIER server Node A.
3. On a sheet of paper, record the following information for each power cable attached to both ProtecTIER nodes:
   • The label of the power cable.
   • The WTI port where the cable is connected (see Figure 1).
4. Remove the old WTI switch.
5. Install the new WTI switch and connect it in exactly the same way as the old WTI.

   Note: In Figure 1 and Table 1, the letters TJ followed by a number (for example: TJ5) indicate which outlet (J5) the associated component plugs into on the Top PDU. The letters BJ followed by a number (for example: BJ8) indicate which outlet (J8) the associated component plugs into on the Bottom PDU.
