Hardware Maintenance Procedures
The procedure for hot-swapping a model A SFCS-1000 AC power supply is as
follows:
WARNING! A replacement DC power supply should
never be placed in an SFCS-1000 that already
contains an AC power supply, and vice-versa.
If these instructions are not heeded, there is a
risk of electrical shock, danger to personal
health, and serious damage to the equipment.
WARNING! It is highly recommended that you use the
included grounding strap when handling this
or any other component.
1. Determine which power supply is defective by examining the
power supplies themselves. A red LED or an extinguished LED
indicates the failed supply. On an SFCS-1000, power supply “1” is
in the slot labeled PS1 on the chassis, while power supply “2” is in
the slot labeled PS2 on the chassis.
WARNING! Failure to perform Step 2 can result in serious
injury to the user or damage to the equipment.
2. Turn OFF the power switch on the front of the defective power
supply. Wait for the yellow SHUTDOWN LED to extinguish
before moving to Step 3.
3. Unplug and remove the power cord from the failed supply.
4. Unscrew the four retaining screws with a 3/32-inch Allen wrench
and pull forward on the handle located below the power cord.
5. Remove the defective supply and prepare to install the new one.
