xSeries 200 Internal SCSI Cabling
EIDE Models
In xSeries 200 models using the EIDE interface for storage device attachment, a two-drop cable is used to attach the standard 15 GB EIDE HDD to one of the EIDE connectors. A
second EIDE controller provides the interface for the IDE CD-ROM drive. A two-drop cable connects the IDE controller to the IDE CD-ROM. Up to two additional EIDE or IDE
devices can be installed (one off of each controller).
SCSI Models
xSeries 200 models with a SCSI adapter are cabled internally with a five-drop, 16-bit wide LVD SCSI cable with a built-in multi-mode active terminator at one end of the cable. The
other end of the cable is attached to the internal 68-pin connector of the standard Ultra160 SCSI adapter. SCSI devices can be connected to any of the five cable connectors. If 8-bit
(narrow) devices are to be installed, a 68- to 50-pin converter P/N 32G3925 is required for each narrow device.
Other Configuration Alternatives
In the case where a RAID controller is used to support internal drives in a xSeries 200, the standard cable is moved from the onboard controller to the RAID adapter. To connect a
tape drive to the onboard or other supported SCSI controller, use the 16-bit multi-mode terminated, two-drop, SCSI cable included with optional Media Bay Tray and LVD Cable Kit
(P/N 10K2340).
External SCSI support can be obtained by installing an optional SCSI adapter or RAID controller and using appropriate external SCSI cabling.
1.The xSeries 200 EIDE controllers support a maximum of four IDE devices per machine including CD-ROM drives, hard disks
and IDE tape drives.
2. Mixing of IDE and SCSI hard disk drives is not supported.
3. Limited to 2 drives in model P/N K812Xxx due to installed tape drive option.
4. Not supported by the external SCSI port included in SCSI models. Select an optional SCSI controller then refer to Appendix D:
Cables-Storage Units-Controllers to confirm the controller supports the desired External Storage Expansion Unit and to select a
supported cable. For HDD or other expansion unit options, see the specific expansion unit section.
5. The EXP300 includes a single 2M Ultra2 SCSI cable and dual hot-swap 500 W redundant power supplies, each with its own
standard country power cord. To convert an EXP300 to a tower form factor, EXP300 Rack-to-Tower Conversion Kit P/N 09N7296
is required.
6. This unit does not include Rack Power Cables P/N 94G7448 when shipped (for attachment to high voltage UPS or PDU).
Standard country power cords only are included. If required, order Rack Power Cables (one for each power supply).
7.Where ‘xx’ represents a specific country code as follows: 51=US/English, 52=European/English, 56=Danish/English, 57=Israel/
English, 58=Italian/English, 59=South Africa/English, 60=Swiss/English, 63=UK/English:- Line Cords/ Publication Country Kits
are included as indicated.
