Installing the A4800A Adapter Looking at Adapter Installation Chapter 2 21 Card Compatibility On-Line Addition (OLA). When on-line adding an interface card, the first issue that must be resolved is whether the new card is compatible with the system. Each PCI slot provides a set amount of power .
Installing the A4800A Adapter Looking at Adapter Installation Chapter 2 22 OLA/R Restrictions for the A4800A The HBA has some restrictions in the OLA/R procedure . These restrictions are explained below . The restrictions are necessary because the SCSI attributes of initiator ID , and speed cannot be changed online for this HB A.
Installing the A4800A Adapter Looking at Adapter Installation Chapter 2 23 Step 4. Locate the card separator/extractor slot where you intend to install the adapter . Step 5. Remove the blank panel aligned with the PCI slot you intend to use. If the blank panel has a bracket screw , save it for reuse during the installation.
Installing the A4800A Adapter Looking at Adapter Installation Chapter 2 24 must invoke the appropriate commands in the SCSI section of the BCH and change the address electronically to whatever is required for the HA configuration being used. Refer to “Checking SCSI Bus Compatibility” on page 36.
Installing the A4800A Adapter Connecting SCSI P eripheral Devices Chapter 2 25 Connecting SCSI P eripheral Devices Connect multiple SCSI devices by chaining them together with shielded, 68-pin, High-Density (HD) cables. The connectors on these cables are keyed to ensure proper pin-1 to pin-1 registration.
Installing the A4800A Adapter Connecting SCSI P eripheral Devices Chapter 2 26 Y ou can connect up to four devices if they are evenly spaced on a 3 m Ultra SCSI cable (0.75 m between devices).
