5.1 Steps to Install
5.1.4 Installation Procedure
Before attempting any of the following steps, make sure that the SF7x
enclosures installed in the array cabinet contain four disk ISEs.
To determine if the SF7x contains two or four drives, simply look at the front
of the enclosure. If you can see two drives in the front of the SF7x, then the
enclosure contains four drives (SF7x–JK variant). If you do not see two drives
in the front of the enclosure, then that enclosure contains only two drives
(SF7x–HK variant). If you wish to verify an enclosure that is already installed
and running in a cabinet or array cabinet, observe the number of 7-segment
displays that are lit on the operator control panel (OCP). If the top two displays
are lit, then the enclosure contains only two RF72 disk ISEs.
The procedure for installing the upgrade kit is in Appendix B.
This section describes the step-by-step procedures for installing an SF7x
storage enclosure in Sx300 storage array.
Be sure to:
• Follow each step in order, and do not skip any steps
• Leave sufficient room to perform the installation (approximately 1.5 meters
to 1.8 meters [5 feet to 6 feet] front and rear of the array)
WARNING
Observe all ESD precautions and procedures. An anti static wrist strap
is inside the front and rear doors.
CAUTION
Do not attempt to pick up or support the SF7x by the handle in the
rear of the enclosure. Doing so will injure the person attempting the
installation or damage the power supply.
To maintain stability, extend only one SF7x storage enclosure or
magazine tape subsystem on the slide mounts at a time.
