Internal Drives Installation (Netfinity 7000-M10 - Type 8680)

•  Diskette
•  Hard disk
•  CD-ROM
•  Tape

Internal Drive Bays: Internal drives are installed in bays.
The server comes with one 3.5-inch, 1.44 MB diskette drive and one CD-ROM drive.

•  The server comes with a preinstalled 3.5-inch, 1.44 MB diskette drive and a preinstalled IDE  CD-ROM drive.
•  The Netfinity 7000 M10 supports one diskette drive only.
•  The server supports four slim-high (1-inch) or two half-high (1.6-inch), 3.5-inch hot-swap hard disk  drives in the hot-swap bays.
•  The hot-swap bays connect to a SCSI backplane.  This backplane is the printed circuit board behind the  bay. The backplane supports up to four hard disk drives.
•  The diskette drive uses 1 MB and 2 MB diskettes.  For optimum use, format 1 MB diskettes to 720 KB and format 2 MB diskettes to 1.44 MB.

SCSI Drives: Some drives have a special design called small computer system interface, or SCSI. This design allows you to attach multiple drives to a single SCSI connector.

Notes:

1.  Any information about SCSI drives also applies to other SCSI devices, such as tape drives.
2.  If you plan to install both internal and external SCSI devices, you must follow the instructions in 'Connecting External Options', in addition to the instructions in this section.

SCSI IDs: Each SCSI device that is connected to an individual integrated SCSI controller needs a unique identification (ID) so that the controller can identify the devices and ensure that different devices do not attempt to transfer data at the same time. (The integrated SCSI controllers operate independently.) If you need to set IDs for SCSI devices, refer to the instructions that come with those devices.

The server automatically sets SCSI IDs for hot-swap hard disk drives, according to the jumper settings on the SCSI backplane. The server uses the hard disk drive SCSI IDs to send status information to the indicator lights above each hot-swap bay.

Note: Do not set the SCSI ID jumpers on hard disk drives.

The SCSI backplane in the server supports up to four hot-swap drives.
Table 9 (below), shows the default SCSI IDs that the backplane assigns for hot-swap hard disk drives.

Table 9. Automatically Assigned SCSI Ds 

Bay	1	2	3	4
ID	0	1	2	3

Note: The default SCSI ID for the SCSI backplane is 14. The default SCSI ID for each controller is 7.

The processing sequence for SCSI devices is set through the SCSISelect Utility program. The default sequence proceeds from the lowest SCSI ID to the highest (0 to 6, then 8 to 15).

Termination: The devices at both ends of the SCSI bus must be terminated. If you attach SCSI devices (internal or external), you must terminate the last device in the chain. The SCSI cable that comes in the server (connected to the SCSI backplane) is terminated.

All the hot-swap drives in the server have automatic termination.

Refer to the information that comes with the SCSI device for instructions about setting device jumpers or switches that control termination.

Preinstallation Steps: Before you install drives in the server, verify that you have all the cables and any other equipment specified in the documentation that comes with the internal drive. You might also need to perform certain preinstallation activities. Some of the steps are required only during the initial installation of an option.

1.  Choose the bay in which you want to install the drive.
2.  Check the instructions that come with the drive to see if you need to set any switches  or jumpers on the drive. Remove any SCSI ID jumpers from the drive.
3.  To install the drive, go to 'Installing a Drive in a Hot-Swap Bay.'

Installing a Drive in a Hot-Swap Bay: The bays on the right front of the server support hot-swap drives only.

Note: You do not have to turn off the server to install hot-swap drives in these bays. However, you must turn off the server when performing any steps that involve installing or removing cables.

Before you begin:

•  Read 'Safety Information'
•  Read the documentation that comes with the drive.

To install a drive in a hot-swap bay:

1.  Determine the bay in which you want to install the drive.
2.  Remove the filler panel -1- from the empty hot-swap bay by inserting the  finger into the depression at the left side of the filler panel and pulling it away from the server.
3.  Install the hard disk drive -2- in the hot-swap bay:
   1.  Ensure the tray handle -3- is open (that is, perpendicular to the drive).
   2.  Align the drive/tray assembly so that it engages the guide rails in the bay.
   3.  Gently push the drive assembly into the bay until the drive connects to the backplane.
   4.  Push the tray handle to the right until it locks.

4.  Check the hard disk drive status indicators to verify that the hard disk drives are  operating properly. See 'Identifying Problems through Status Indicators' for details.

5.  Note: If the server has a RAID adapter installed, refer to the RAID adapter  documentation for details about configuration requirements.
