Remove the cable that connects the CD-ROM to the IDE connector on the power backplane. b. Using the two-drop cable that came with the IDE option, connect the CDROM and IDE device you are installing to the IDE connector on the power backplane. c. Set the jumper on the back of the new IDE option as secondary. 12. Connect a power cable to the back of the drive. Power cables for removablemedia drives come installed in the server. The connectors are keyed and can be inserted only one way. 13. If you are installing another 5.25-inch drive, do so now. Otherwise, continue with step 14.. 14. Connect the shuttle. a.

Installing memory-module kits Before you continue with the memory-installation procedure, review the following: • Review the information in "Before you begin" on page 60. • All the DIMMs installed in each set must be the same size and speed, but all the sets do not have to contain DIMMs of the same size and speed. • The memory board contains 16 DIMM connectors and supports 4-way memory interleaving. • Install only 3.3 V, 168-pin, 8-byte, registered DIMMs. Only 100 MHz, 72-bit, registered, synchronous, error correcting code (ECC), SDRAM configuration DIMM memory is supported for the 128 MB, 256 MB, 512 MB and 1 GB (when available) DIMMs. • If you install 4 GB of memory, some of the memory is reserved for system resources. The amount reserved for system resources depends on the configuration of the server. Installing options 71
