The xSeries 350 contains a DASD backplane supporting three hot-swap, SCA-2 compliant drive bays. The backplane is connected to one of the internal connectors
of the integrated dual-channel Ultra160 SCSI controller through a 16-bit LVD SCSI cable. An optional 3-Pack Ultra160 Hot-Swap Expansion Kit
(P/N 33L5050) can be installed to provide additional internal HDD storage capacity. Within this option are two 16-bit LVD SCSI cables. One can be attached from the
3-Pack Ultra Hot-Swap backplane to the second connector of the dual-channel Ultra160 SCSI controller, the other, through the use of a repeater card included with
the option, can be cabled directly to the standard backplane.
In configurations where external SCSI device attachment is required instead of additional internal HDD storage, a second 16-bit LVD SCSI cable is included with the
server. One end of the cable can be attached to the second Ultra160 connector and the other is attached to the external 0.8mm VHDCI connector on the back of the
chassis. This provides an external connection to support LVDS devices.

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.
1. Network operating systems may limit the maximum amount of addressable memory. See operating system
specifications for further information.
2. To obtain the quantity of memory identified in the “Total Memory” column, select the appropriate row and order the
quantity of RDIMMs identified in all columns for that row. Example: For 2GB, order 4 x 33L3113 plus 4 x 33l3115.
3. Requires removal of standard RDIMMs.

1. Due to four-way interleaving all RDIMMs installed in each set must be the same size, but all the sets do not have to
contain RDIMMs of the same size. Install RDIMM sets in numerical sequence from one to four. Chipkill support is
provided on the memory card.
