HP 3PAR T-Class Installation and Deinstallation Guide

to fully seat the drive magazine in the chassis. When fully seated, the drive handle of the
magazine rests against the front of the drive chassis housing.
CAUTION: Drive magazines should glide in easily. If a drive magazine does not insert
smoothly, do not force it. Check if the magazine is properly aligned with the guide notch at
the top of the drive bay and apply moderate pressure toward the left side of the magazine
while inserting.
NOTE: If you have difficulty inserting drive magazines into drive chassis that also have drive
magazine filler panels installed, loosen the screws that fasten the adjacent filler panels to
enable you to insert the drive magazines more easily.
3. After the drive magazine is fully inserted, use a #2 Phillips screwdriver to tighten the captive
screw below the magazine handle, as shown in “Securing a Drive Magazine” (page 62). Do
not overtighten.

4. For highest availability and data protection, place drive magazines on different loops and
internal power domains by loading them in the order established in “Procedure for Loading
Drive Magazines” (page 60) as illustrated by “Pattern for Loading Initial Drive Magazines
into the Drive Chassis” (page 60).
NOTE: See the HP 3PAR Systems Assurance Document for additional information about
drive magazine allocation for your system configuration.
After installing all the drive magazines, some drive chassis may contain empty slots. Install a
drive magazine filler panel into each empty drive slot.
Installing Drive Cage Filler Panels
Any drive cage partially populated with magazines requires drive magazine filler panels to promote
the necessary airflow pattern within the cage. The drive magazine filler panel is a small piece of
sheet metal and similar in same size as the face of a drive magazine, as shown in Figure 53
(page 63). Cover all unpopulated slots with a drive magazine filler panel.
CAUTION: To prevent overheating of the drive chassis, do not operate a system unless all bays
in the drive chassis are filled with drive magazines or sealed with drive magazine filler panels.
