Fan-and-Power-Supply Assemblies
Attention: If you are servicing the 7133 under concurrent maintenance (see “Concurrent
Maintenance” on page 3-1), ensure that you have only one fan-and-power-supply
assembly removed from the 7133 at any time.
Notes:
1. Unless you have a particular reason to do so, do not turn off the using system or the
7133 when removing or installing fan-and-power-supply assemblies.
| 2. The diagrams in these instructions show a 7133 Model 010. The procedure for
| Models 020, 500, and 600 is the same, except that for Models 500 and 600,
| everything is turned through 90 degrees.
