Non-Hot-Swap
Models
xSeries 220 non-hot-swap models are cabled internally with a five-drop, 16-bit wide LVD SCSI cable with a built-in multi-mode active terminator on one end of the cable. The other
end of the cable is attached to the internal 68-pin connector of the integrated Ultra160 SCSI controller. 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.
Hot-Swap Models
xSeries 220 hot-swap models are cabled internally with a two-drop, 16-bit wide LVD SCSI cable. One end is connected to the internal 68-pin connector of the integrated Ultra160
SCSI controller. The first drop is designed to support a SCSI device in the 3.5-inch non-hot-swap bay, while the second drop is connected to the hot-swap SCSI backplane.The SCSI
backplane provides termination for the SCSI bus.
Other Configuration Alternatives
In the case where a RAID controller is used to support internal drives in a xSeries 220, 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, the two-drop cable from Media Bay Tray and LVD Cable Kit P/N 10K2340 must be used.
External SCSI support can be obtained by installing an optional SCSI adapter or RAID controller and using appropriate external SCSI cabling.

1. Bay 2 does not support HDD options. It can be used for removable
media devices such as tape drives.
2. These bays are configured as hot-swap bays on models K52AXxx,
K53AXxx, K54AXxx.
