A maximum of three drives may be installed.
Figure 6–1 shows the major subassemblies of the SA7x enclosure. Except for
the RA70 disk drive designation, this illustration is accurate for all the SA7x
enclosures.
CAUTION
Do not attempt to install a disk drive unless you have received training
in electrostatic discharge (ESD) procedures and have taken proper
precautions against ESD. Wear an ESD grounding strap properly
connected to a known ground. Refer to Figure 1–4 for the proper use of
an ESD grounding strap.
Note
If the SA7x enclosure is installed in a storage array cabinet when you are
attempting to install or remove an RA7x disk drive, you must first remove
or open either the cabinet’s front or rear panel. See the appropriate
storage array guide for instructions on removing and installing cabinet
panels.
