Installation 1. Determine which slots, 1 through 14, will contain disk modules and which will contain fillers. - If DIP switch 1 is set to "|" (full bus mode), choose any slots for disk modules or fillers. In full bus mode, the SCSI address 7 is reserved for the host bus adapter. If more than one host bus adapter connects the disk system to other hosts, then a disk module must be removed from the slot whose SCSI address corresponds to the SCSI address of the additional host bus adapter. The most host bus adapters supported on this disk system is two. - If DIP switch 1 is set to "0" (split bus mode), the left BCC is on the high numbered bank (with disk slots 8, 9, 10, 11,12, 13, and 14) and the right BCC is on the low numbered bank (with disk slots 0, 1, 2, 3, 4, 5, and 6) of disk slots. - At least one disk module must be installed. 2. Put on the ESD strap and attach the other end to ground. Caution Disk modules are fragile. Handle carefully. Be careful to grasp the disk module by its handle and avoid touching exposed circuitry. 3. Verify that the disk module extraction handle (A in Figure 46) is open by placing a finger behind the extraction handle and pushing the latch tab toward your finger. 4. Align and insert the disk module into its slot. 5. Push the disk module as far as it will go into the selected slot. Note Install disks left to right for easier insertion. 6. Close the cam latch by pushing the extraction handle toward the disk until it clicks. The cam action draws the disk module completely into the slot and seats the connecting pins on the midplane. 7. Repeat steps 4 through 7 to install additional disk modules. 8. Install disk fillers in the remaining slots. Caution Every slot must contain either a disk module or filler panel for proper cooling.

Installation
1.
Determine which slots, 1 through 14, will contain disk modules and which
will contain fillers.
—
If DIP switch 1 is set to “|” (full bus mode), choose any slots for disk
modules or fillers. In full bus mode, the SCSI address 7 is reserved for the
host bus adapter. If more than one host bus adapter connects the disk
system to other hosts, then a disk module must be removed from the slot
whose SCSI address corresponds to the SCSI address of the additional
host bus adapter. The most host bus adapters supported on this disk
system is two.
—
If DIP switch 1 is set to “0” (split bus mode), the left BCC is on the high
numbered bank (with disk slots 8, 9, 10, 11,12, 13, and 14) and the right
BCC is on the low numbered bank (with disk slots 0, 1, 2, 3, 4, 5, and 6)
of disk slots.
—
At least one disk module must be installed.
2.
Put on the ESD strap and attach the other end to ground.
Caution
Disk modules are fragile. Handle carefully. Be careful to grasp the
disk module by its handle and avoid touching exposed circuitry.
3.
Verify that the disk module extraction handle (A in
Figure 46
) is open
by placing a finger behind the extraction handle and pushing the latch
tab toward your finger.
4.
Align and insert the disk module into its slot.
5.
Push the disk module as far as it will go into the selected slot.
Note
Install disks left to right for easier insertion.
6.
Close the cam latch by pushing the extraction handle toward the disk
until it clicks. The cam action draws the disk module completely into
the slot and seats the connecting pins on the midplane.
7.
Repeat steps 4 through 7 to install additional disk modules.
8.
Install disk fillers in the remaining slots.
Caution
Every slot must contain either a disk module or filler panel for
proper cooling.
