Important safety information
CAUTION:
Use extreme caution when installing and pulling units from the rack; they can slip and fall, causing
damage to the StoreOnce 5500 System or injury. Hewlett Packard Enterprise is not responsible for
any damage or injury caused by the mishandling of the StoreOnce System.
WARNING:
The disk enclosure with the base configuration of 15 drives installed weighs 103 kg (227 lbs). With
all drives and components installed, the enclosure weighs 160 kg (352 lb). To reduce the risk of
personal injury or damage to the equipment:
• Observe local occupational health and safety requirements and guidelines for manual material
handling.
• Use caution and get help to lift and stabilize disk enclosures during installation or removal,
especially when the disk enclosure is not fastened to the rack.
Installing the rails and locking nuts
The rack rails are marked for easy identification. The left rack rail is marked "L" and the right rack rail is
marked "R." To install the rack rails:
Determine where the additional disk enclosure will be installed and install the rails and locking nuts, as
follows:
Procedure
1.
Begin with the left rack rail. Align the end of the rail with the rear rack column.
2.
Slide the rack rail closed until the end of the rail is locked in place, wrapping behind the rear rack
column.
3.
Slide the front end of the rail to the rack front column. When fully seated, the rack rail will lock into
place.
4.
Repeat the procedure for the right rack rail.
5.
Insert the eight locking nuts into the rack; two on each column. These will be used to secure the
thumbscrews on the front of the disk enclosure and the mounting brackets that will be attached to the
rear of the disk enclosure. To locate the correct position for the locking nuts, count up 4U from the
location of the rails (1). The nuts go either side of the +4U position on each rack column (2).
