2. Install the non-standard (tall) 3 rank DIMM baffle, route the cable on the DIMM baffle, and then connect the cable to the mezzanine option. 3. Install the access panel ("Access panel" on page 28). Recovering data from the FBWC If the workstation blade fails, use the following procedure to recover data temporarily stored in the FBWC. CAUTION: Before starting this procedure, read the information about protecting against electrostatic discharge ("Preventing electrostatic discharge" on page 25). 1. Set up a recovery workstation blade station using an identical workstation blade model. Do not install any internal drives or FBWC in this workstation blade. (HP recommends this option.) 2. Power down the failed workstation blade ("Power down the workstation blade" on page 26). 3. Transfer the hard drives from the failed workstation blade to the recovery workstation blade station. 4. Remove the SAS controller (on page 54), NAND flash module (on page 55), and capacitor pack ("Removing the capacitor pack" on page 56) from the failed workstation blade, and install the controller, NAND flash module, and capacitor pack in the recovery workstation blade. 5. Power up the recovery workstation blade. If data was saved on the NAND flash module, then a 1792 POST message appears, stating that valid data was flushed from the cache. This data is now stored on the drives in the recovery workstation blade. If the SAS controller fails, use the following procedure to recover data temporarily stored in the FBWC.

2.
Install the non-standard (tall) 3 rank DIMM baffle, route the cable on the DIMM baffle, and then connect
the cable to the mezzanine option.
3.
Install the access panel ("

" on page
28
).
Recovering data from the FBWC
If the workstation blade fails, use the following procedure to recover data temporarily stored in the FBWC.
CAUTION:
Before starting this procedure, read the information about protecting against
electrostatic discharge ("
Preventing electrostatic discharge
" on page
25
).
1.
Set up a recovery workstation blade station using an identical workstation blade model. Do not install
any internal drives or FBWC in this workstation blade. (HP recommends this option.)
2.
Power down the failed workstation blade ("
Power down the workstation blade
" on page
26
).
3.
Transfer the hard drives from the failed workstation blade to the recovery workstation blade station.
4.
Remove the SAS controller (on page
54
), NAND flash module (on page
55
), and capacitor pack
("
Removing the capacitor pack
" on page
56
) from the failed workstation blade, and install the
controller, NAND flash module, and capacitor pack in the recovery workstation blade.
5.
Power up the recovery workstation blade.
If data was saved on the NAND flash module, then a 1792 POST message appears, stating that valid
data was flushed from the cache. This data is now stored on the drives in the recovery workstation
blade.
If the SAS controller fails, use the following procedure to recover data temporarily stored in the FBWC.
