4. Remove the lifting device.
5. Using the long pan-head screws (10-32 x 3/4-inch) that came with the disk
drive, connect the chassis retaining brackets (mounted on the side of the disk
drive) to the cabinet. (Refer to Figure 5–19.)
6. Replace the OCP at the top of the drive. If the bezel connector cap is in the
way, remove it and replace the OCP. Then move the bezel connector cap to the
bottom connector as shown in Figure 5–4.
5.7.3 Installing SDI Cables and Power Cords
The SA900 storage array is shipped with internal SDI cables and power cords
installed for the installed storage devices. When you install RA9x disk drives you
must install the internal SDI cables and power cords. External SDI cables are
ordered separately and shipped with the add-on. (Table 3–2 lists the external SDI
cables.)
Storage devices are connected by SDI cables to one of the five sets of eight
connectors on each bulkhead.
• The RA9x drive uses two SDI cables.
• The SA7x enclosure uses two special one-to-four cables.
• Each cable has four bulkhead connectors.
The H9A00 cabinet includes a left and a right vertical I/O bulkhead. (See
Figure 5–20.) The SA900 storage array can accommodate a maximum of 10 RA9x
disk drives or 10 SA7x enclosures for a maximum of 80 ports. A total of ten
devices can be connected to the I/O bulkheads.
Use the following procedure to install and connect SDI cables and power cords:
1. On the rear of the RA9x disk drive, make sure that the Line Voltage Selector
switch is in the proper position (120 Vac or 240 Vac) and that the RA9x drive
circuit breaker is off.
2. Install the internal SDI cables, shown in Figure 5–20, as follows:
a. Connect cables from drives and enclosures on the left side of the cabinet
to the left vertical I/O bulkhead.
b. Connect cables from drives and enclosures on the right side of the cabinet
to the right vertical I/O bulkhead.
c. Connect the internal SDI cable connectors to the Port A and Port B
connectors on the rear of the RA9x disk drive.
d. Connect the RA9x Port A cable to the I/O bulkhead connectors and secure
with two 6-32 x 3/8-inch sems screws. Port A is always the top connector
in each group of eight connectors (Figure 5–20).
e. Connect the RA9x Port B cable to the I/O bulkhead connectors and
secure with two 6-32 x 3/8-inch sems screws. Port B is always the second
connector from the top in each group of eight connectors.
3. Connect the power cords, shown in Figure 5–21, to the rear of the RA9x disk
drive.
