2.5Configuring On-Board Hardware

This section provides the procedures for adding or replacing the on-board hardware components such as memory modules, a Compact Flash card, and the time-of day (TOD) battery. Read and perform the procedures, as necessary, before installing the Netra CP3260 blade server into the chassis.

2.5.1Adding or Replacing FB-DIMM Memory Modules

The Netra CP3260 blade server supports a total of 8 FB-DIMMs and a maximum memory capacity of 16 Gbytes (using eight 2-Gbyte DIMMs). FIGURE 2-1shows the location of the FB-DIMMs. The Netra CP3260 blade server accommodates the following:

■Eight standard FB-DIMMs, buffered, and registered

■1-Gbyte or 2-Gbyte FB-DIMM modules

Note – You cannot mix 1-Gbyte and 2-Gbyte FB-DIMMs. All eight DIMMs must be the same density (that is, all 1-Gbyte or all 2- Gbyte FB-DIMMs).

The Netra CP3260 blade server supports FB-DIMM memory modules that have the following characteristics:

■Each DIMM has a 72-bit-wide data bus (64+8 ECC) and up to 14 address bits.

■Memory controller supports 128-bit data plus 9-bit error-correcting code (ECC).

■Maximum of 16 Gbytes (eight 2-Gbyte FB-DIMMs) or 8 Gbyte (eight 1-Gbyte FB-DIMMs).

■FB-DIMM @1.55 volts or FB-DIMM@1.8 volts

For information about sensors, refer to the Netra CT 900 Software Developer’s Guide (819-1175).

For additional information, see Section 5.2.2, “Memory Subsystem” on page 5-9. shows the location of the DIMMs.
