Power Supply Placement In The B08S; Power Supply Placement In The B16S - IBM s-series Installation And User Manual

Figure 11. Power supply placement in the B08S
In the B16S, the system power supplies occupy slot numbers 1 - 4 in the top row
with the redundant supplies in slot numbers 3 and 4. The POE power supplies
occupy slot numbers 5 - 8 in the bottom row. Figure 12 shows power supply
placement.

The installed power supplies provide power to all chassis components, sharing the
workload equally. If a power supply fails or overheats, the failed power supply's
workload is redistributed to the redundant power supply, if one is present.
The power supplies are hot swappable, which means you can remove and replace
them without powering down the system. You can remove and insert a power
supply without opening the chassis. If the device contains redundant 12-volt power
supplies, you can remove one of the power supplies without interrupting operation.
The remaining power supply provides enough power for all the ports. For more
information about removing and installing the power supplies, see "Installing or
replacing a power supply" on page 107.
CAUTION:
The power supplies are hot swappable, which means they can be removed
and replaced while the chassis is powered on and running. However, IBM
recommends that you disconnect the power supply from the wall outlet
before removing and replacing the supply. The device can be running while a
power supply is being installed or removed, but the power supply itself
should not be connected to a power source. Otherwise, you could be injured
or the power supply or other parts of the device could be damaged.
