Specifications

8. Coil any excess power cord in front of the power controller.
9. Connect the external SDI cables in the SA900 storage array. Be sure to
tighten the captive screws when connecting the external cables to the
bulkhead.
10. Slide the external SDI cables through the appropriate slot on the filler panel.
If necessary, remove the cable retainers on the filler panel to more easily
access the slot. Then, replace the cable retainers.
5.11.4 Completing the Installation
Complete the installation as follows:
1. Restore power to the cabinet as explained in Section 3.9.
2. Turn on all storage devices in the cabinet.
3. Spin up all drives and place them on line.
4. Check out all storage devices as described in the component user guide or
service manual.
5. Make sure that the rear panel will clear the external cables. If necessary,
adjust the side panels to provide additional clearance as described in
Section 3.4.
6. Replace the rear panel and close the front panel. (Refer to Figure 3–9.)
5.12 Installing a TA8x7 Series Storage Subsystem
Note
Use these procedures to install either a TA857 or a TA867 storage
subsystem.
A TA8x7 series storage subsystem is actually two components:
• The magazine tape subsystem (TZ8x7)
• The SCSI/SDI adapter
When shipped from the factory, the adapter and the tape subsystem are located in
the center of the SA900 cabinet. Figure 5–41 lists the add-on sequence numbers
for TA8x7 series storage subsystems. These are the only authorized positions.
Make sure to fill the empty positions in the sequence order. If the positions are
already filled by other components, move the components to another position.
Installation Restrictions
TA8x7 storage subsystems are only installed in SA900 storage arrays.
They are not installed in any other storage array.
Your responsibilities for installing a TA8x7 series storage subsystem includes the
following:
• You must install and route the external SDI/STI cable between the adapter-
interface and the HSC controller, including those installed at the factory.
• You must install the mounting hardware.
