Replacing An Fpga Board As A Fru; Requirements For Replacing Fpga Board; Replacing The Fpga Board - Hitachi 3090 G2 Hardware Reference Manual

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).
An FPGA board is also known as the main FPGA board (MFB).
Contact Hitachi Support Connect to determine whether your FPGA can be replaced as a
FRU.
Note: If you receive a replacement FRU, in some instances, a complete server
FRU may be received, instead of just the FPGA FRU.

Requirements for Replacing FPGA board

MFB replacement may not be performed while the server is operation; the server must
be shut down and removed from the rack before the replacement procedure can be
started. After the MFB has been replaced, the server can be put back into the rack,
reattached, and restarted.

Replacing the FPGA board

MFB replacement may not be performed while the server is operation; the server must
be shut down and removed from the rack before the replacement procedure can be
started. After the MFB has been replaced, the server can be put back into the rack,
reattached, and restarted.
Procedure
1. Using NAS Manager, log in and select Reboot/Shutdown from the Server Settings
page to display the Restart, Reboot and Shutdown page. Note that the page has
different options depending on the configuration of your system.
2. Click Shutdown to stop file serving EVSs on the server, and then shut down and
power off the server.
3. Remove the fascia. See
4. Disconnect all power and networking cables from the server.
5. Completely remove the server from the rack.
