Note: If you are installing more than one DS4800 Storage Subsystem, it is
recommended that you install each DS4800 and its associated
storage expansion enclosures in a separate rack cabinet.
v If appropriate, allow for possible later installation of other units.
v If necessary, remove the rack power distribution units (PDUs) before you
install the support rails.
v For procedures and more information, refer to the installation and service
guide, or equivalent, for the rack cabinet.
6. Starting with the left rail, use a medium flat-blade screwdriver to loosen the two
flat-head rail adjustment screws. See Figure 14 on page 36.
7. Hold the front of the left rail against the inside of the front rack-mounting
flange, and then extend the rear of the support rail until it makes contact with
the rear rack mounting flange. The alignment pins at the rear of the rail should
slide into the holes at the rear of the rack.
8. From the front of the rack, with the rail mounting flanges inside of the front
rack-mounting flange, use the 5/16 (8 mm) hex nut driver to thread and loosely
tighten the lower M5 screw only. Use the front rack mounting template in this
chapter (or use the copy in Appendix C, “Rack mounting templates,” on page
189) to locate the proper rack mounting hole for installing this screw.
Attention: Do not completely tighten the screw until you have installed the
DS4800 in the rack cabinet.
9. From the rear of the rack, thread and loosely tighten two M5 screws using the
5/16 (8 mm) hex nut driver. Use the rear rack mounting template in this
chapter (or use the copy in Appendix C, “Rack mounting templates,” on page
189) to locate the proper rack mounting holes for installing these screws. Do
not completely tighten the screws until you have installed the DS4800 in the
rack cabinet.
When you are finished installing the left rail, the rail should be attached to the
cabinet using one M5 screw in the front and two M5 screws at the back. All
three M5 screws should be loosely tightened.
10. Repeat step 6 through step 9 for the right rail.
11. Tighten the rail adjustment screws on both rails.
12. Continue with “Installing the DS4800.”
Installing the DS4800
The DS4800 Storage Subsystem contains two controllers, two power supply and
fan units, and one interconnect-battery unit. The RAID controllers are located at the
back of the unit. The two power supply and fan units and the interconnect-battery
unit are located behind the front bezel.
Figure 15 on page 38 shows the front bezel of the DS4800 Storage Subsystem, a
front view without the cover, and a back view. Figure 15 on page 38 also shows the
locations of the components that are referenced during this installation procedure.
