I/O board 1. Midplane connector 2. I/O function card slot 3. Voltage Regulator Module (VRM) connectors 4. Advanced System Management PCI adapter slot 5. USB 1 and USB 2 port connectors 6. PCI switch-card connector

Resolving The Problem

I/O board

i/o board

1. Midplane connector
2. I/O function card slot
3. Voltage Regulator Module (VRM) connectors
4. Advanced System Management PCI adapter slot
5. USB 1 and USB 2 port connectors
6. PCI switch-card connector
7. Hot-plug, 64-bit, PCI slots 10-12 (bus A, 33MHz)
8. Hot-plug, 64-bit, PCI slots 8-9 (bus B, 66MHz)
9. Hot-plug, 64-bit, PCI slots 6-7 (bus C, 66MHz)
10. Hot-plug, 64-bit, PCI slots 1-5 (bus D, 33MHz)
11. Hot-plug external attention/fail LED for PCI bus. (green blink = attention, amber = defective PCI adapter)
12. Hot-plug internal attention/fail LED for PCI slot. (green blink = attention, amber = defective PCI adapter)
13. Hot-plug power LED for PCI slot (green solid, on)

Processor controller board

processor board

1. Midplane connector
2. Processor-cage release latches (4x)
3. Processor-daughterboard slot B connector (secondary slot)
4. Cache coherency filter-card connectors
5. Processor core-frequency selection jumper block
6. LED card connector
7. Processor-daughterboard slot A connector (primary slot)

Processor daughterboard

processor daughterboard

1. Processor-controller board connector

Note: The server supports two processor daughterboards.

Memory board

memory board

1. Midplane connector
2. DIMM connectors (J1-J16)

Note: The server supports two memory boards.

The server uses 100MHz, 168-pin, PC100 registered synchronous dynamic random-access memory (SDRAM), industry-standard DIMMs with error checking and correction (ECC).

Memory expansion
DIMM size 16
Connectors
(1 Board)		 32
Connectors
(2 Boards)
128MB 2GB 4GB
256MB 4GB 8GB
512MB 8GB 16GB

Memory installation requirements
DIMM sizes 128MB, 256MB, 512MB
DIMM poulation order for a
single board configuration -
standard memory board (A)		 A1, A5, A9, A13, A3, A7, A11,
A15, A2, A6, A10, A14, A4, A8,
A12, A16
DIMM poulation order for a
dual board configuration -
standard memory board (A) and
optional memory board (B)		 A1/B1, A5/B5, A9/B9, A13/B13,
A3/B3, A7/B7, A11/B11,
A15/B15, A2/B2, A6/B6,
A10/B10, A14/B14, A4/B4,
A8/B8, A12/B12, A16/B16

Notes:

  1. The 100MHz DIMMs support the registered mode of operation.
  2. Install DIMMs with a maximum height of 4.32cm (1.7 inches).
  3. The server comes with one standard (preinstalled) memory board (A), and one or more DIMMs installed on this memory board. You can install an optional memory board (B). Both the standard memory board (A) and the optional memory board (B) contain 16 DIMM connectors (J1-J16)
  4. When you install DIMMs in both the standard memory board (A) and the optional memory board (B), you must install them in matching pairs with the same part number, in the same slot on each memory board; for example: J1/J1, J5/J5, J9/J9 ... and so on.
SCSI backplane

scsi backplane

1. Media power connector
2. Wide (16-bit) SCSI connector
3. SCSI Hot-swap drive connector (on opposite side of backplane)
