System board component locations
The following illustration shows a layout of the system board and identifies system board components. You might need to refer to this figure before you install hardware in the server, or when you record information in the tables in this chapter. You might also need to refer to this figure when you set configuration jumpers on the system board.

System board jumpers
Table 18 describes the jumpers on the system board. The numbers in the table correspond to the highlighted numbers on the illustration in "System board component locations".

Note
Turn off the server, and disconnect the power cords before moving any jumpers.

Table 18. System board jumpers

Jumper Name

Description

8 J11 Disable RAID controller

The default position is Enabled (jumper on pins 1 and 2).
Move the jumper to pins 2 and 3 to disable the RAID controller.

9 J45 Reserved

The default position is a jumper on pins 2 and 3.

10 J32 Power-on control with extension cable

The default position is normal operation (jumper on pins 1 and 2). Moving the jumper to pins 2 and 3 allows the power supply to be
turned on without a power switch assembly or Netfinity Advanced System Management Processor. A cable is connected to these
pins to allow easy access while the processor support tray is still installed; its white wire indicates pin 1.

11 J15 RAID download

The default is no jumpers on the pins. This jumper block is used when the RAID adapter EEPROM is being updated.

12 J25 Reserved

The default position is a jumper on pins 1 and 2.

13 J9 Reserved

The default position is a jumper on pins 1 and 2.

20 J34 Reserved

The default position is a jumper installed on pins 1 and 2.

21 J29 Reserved

The default position is a jumper installed on pins 1 and 2.

22 J26 RS-485

The default is no jumper installed on J26.

24 J51 Disable Advanced System
Management Processor

In normal operation, there is no jumper on J51. Installing a jumper on J51 disables the Netfinity Advanced System Management
Processor. A jumper should only be installed on J51 for diagnostic purposes. Normal operation of the server with J51 jumpered is
not supported.

A system operated in this manner is limited in the following ways:

1. No system error logging.
2. No monitoring of system functions for problem.
3. No automatic recovery after an NMI error.
4. Error indication ability is severely limited.

27 J24 Power on password override

Changing the position of this jumper bypasses the power-on password check if the jumper has been moved since the server was last powered on. You do not need to move the jumper back to the default position after the password is overridden.

Changing the position of this jumper does not affect the administrator password check if an administrator password is set.

28 J30 Flash ROM page swap

The default position is a jumper installed on pins 2 and 3. Changing the position of this jumper will change which of the two pages of Flash ROM is used when the system is started.

46 J5 Disable Ethernet controller

The default position is Enabled (jumper on pins 1 and 2). Move the jumper to pins 2 and 3 to disable the Ethernet controller.

47 J14 Disable video controller

The default position is Enabled (jumper on pins 1 and 2). Move the jumper to pins 2 and 3 to disable the video controller.
