4-9 Changing the Power Distributor Board
The SC848 chassis requires a power distributor. The power distributor provides
failover and power supply redundancy. In the unlikely event you must change the
power distributor, do following:
Changing the Power Distributor Board
1. Power down the system, unplug the cords from the back of the power sup-
plies and remove the chassis top cover.
2. Unplug the fan cables from the motherboard, and then remove the middle fan
bracket as described on page 4-7.
3. Remove all power distributor board cables from the motherboard, backplane,
and other components and remove all power supplies.
4. Locate the power distributor board bracket underneath the chassis floor,
between the power supply and the HDD backplane.
