Item Description
1 PSU fan
2 Power plug
3 Retaining latch
4 Handle
5 DC power LED
6 Malfunction or failure LED
7 AC power LED
Procedure
1. Remove the power cord from the PSU.
2. Move the retaining latch to the right (you may hear a slight click if the
PSU moves when the latch disengages).
3. Using the handle on the PSU, pull the PSU out from the back of the
server until you can completely remove the PSU from the chassis.
4. Insert the replacement PSU. The retention latch should click into position
all the way to the left when the PSU is fully inserted.
If the PSU that is not being replaced is receiving mains power when the
replacement PSU is fitted, the fan on the replacement PSU becomes
active.
5. Connect the power cord to the back of the PSU.
The PSU should start as soon as the power connection is made. If the
PSU does not start immediately, make sure the mains power circuit is live
and that the other end of the power cable is connected to a live outlet.
Replacing an FPGA board as a FRU
Typically, when an FPGA board fails, the whole Hitachi NAS Platform server is
replaced. However, in some cases with the HNAS 3080 and 3090 platform
models, an FPGA board may be replaced as a field replaceable unit (FRU).
