Configuration Field Replaceable Unit (FRU) Configurations Figure 2-3. DDS-3 Tape Drive Settings for Data Compression Operation Mode Operation Mode Switches Compression Disabled, No Host Control Compression Enabled, No Host Control Compression Disabled, Host Can Control Compression Compression Enabled, With Host Control Default Setting Floppy Disk Drive (Optional) Configuration The optional 3.5-inch floppy disk drive requires no ID, switch, or jumper settings. Memory J5xxx Memory Configuration The J5xxx workstation has eight memory slots, labeled 0 to 7. Memory DIMMs can be installed individually in this workstation. The DIMMs for this workstation currently come in 256 MB and 512 MB sizes (Product Numbers A4994A and A4995A, respectively). This workstation comes with one 512 MB DIMM as its standard configuration from the factory. Thus, currently the minimum memory configuration for this workstation is 512 MB, and the maximum is 4 GB. DIMMs should be loaded in the order shown in Figure 2-4 on the next page, with slot 0 being the first DIMM loaded, and 7 being the last DIMM loaded. Different sizes of DIMMs can be loaded in this workstation (that is, 256 MB DIMMs can be loaded with 512 MB DIMMs). Chapter 2 39

Floppy Disk Drive (Optional) Conﬁguration

The optional 3.5-inch ﬂoppy disk drive requires no ID, switch, or jumper settings.

Memory

J5xxx Memory Conﬁguration

The J5xxx workstation has eight memory slots, labeled 0 to 7. Memory DIMMs can be

installed individually in this workstation. The DIMMs for this workstation currently come

in 256 MB and 512 MB sizes (Product Numbers A4994A and A4995A, respectively). This

workstation comes with one 512 MB DIMM as its standard conﬁguration from the factory.

Thus, currently the minimum memory conﬁguration for this workstation is 512 MB, and

the maximum is 4 GB.
