2.1. Procedures for assembling
The PS-7000 can be assembled in the reverse order of disassembling, however, to ensure the accuracy
and to protect the HDD from any shocks, some procedures should be changed. In this section, only
the difference (from the simple reversed procedures for disassembling) and special cares to be taken
are explained.
(1) Follow the Steps 13 to 7.
(2) In Step 6, without fully tightening the screws, put them in the proper places of the Stand. (To
ensure the accuracy of assembling the other components into the PS-7000.)
(3) Follow the Steps 5 and 4.
(4) In Step 3, install the DRAM SIMMs (Step 3-2), and skip installation of HDD (Step 3-1).
(5) In Step 2, slide the Left Side Cover into the Main Frame first and then the Right one. While
screwing the Left Side Cover, leave the Right one without screws. (To ensure the accuracy of
assembling the other components into the PS-7000.)
(6) Tighten the screws of the Stand, which were left not fully tightened in (2), and slide the Right Side
Cover off from the Main Frame.
(7) Return to Step 3-1, to install the HDD. If the HDD is replaced, follow the directions on page 1-5,
"3.2. HDD." Extreme care should be taken not to apply any shocks to the HDD.
