Nonhot-swap Models
xSeries 220 nonhot-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 (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 nonhot-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.

This table does not represent all possible memory configurations. Memory modules may vary in price per MB.
Selection of smaller RDIMMs may provide a more cost-effective alternative to using larger RDIMMs. Select the
desired total memory from the appropriate column (Standard Model128MB), then select a quantity in that row
from one of the RDIMM columns.
1. Network operating systems may limit the maximum amount of addressable memory. See operating system
specifications for further information.
2. Requires removal of standard memory.
