Changing Flash PROM Jumpers

This document accompanies the standalone CD-ROM containing the new firmware code for updating your system's flash PROM. This document is intended for:

Network administrators

System administrators

Network and system service providers

Advanced system users

This chapter describes the procedure for manually changing flash PROM jumper settings (or front panel keyswitch settings) in your system.

Note - The procedures in this document apply to the so-called "Standalone Flash PROM Utility." This utility is what you typically use to perform a firmware update from CD-ROM or a downloaded image. These procedures do not apply to the flash PROM utility that is bundled with the Solaris™ Operating System.

1.1 Introduction

Sun Ultra™, Sun Enterprise™, Ultra Enterprise™, Sun Blade™, Sun Fire™, and Sun Netra™ systems that conform to the Sun4U™ architecture use flash programmable read-only memory (PROM). Flash PROMs enable you to:

Reprogram specific code blocks

Remotely reprogram the PROM chip over a local area network (LAN)

1.2 Changing Flash PROM Jumpers

The Sun Ultra, Sun Enterprise, Ultra Enterprise, Sun Blade, Sun Fire, and Sun Netra systems are equipped with flash PROM jumpers. These flash PROM jumpers are usually located on the motherboard, though this varies from system to system. These jumpers enable you to:

Select or deselect the flash PROM

Enable or disable updating of the flash PROM

Select the location of the flash PROM code for system booting

1.2.1 Changing Jumper or Keyswitch Settings

Before updating the flash PROM, use this procedure to change the write-protect/write-enable jumper or keyswitch setting.

TABLE 1-1 Sun4U Architecture Jumper and Keyswitch Settings
Server/Workstation	Write-Protect/ Write-Enable	Front Panel Keyswitch?	Jumper	Reference
Sun Enterprise 250	Write-enable	Yes	J2704	"Invalid Cross-Reference Format"
Ultra Enterprise 450	Write-enable	Yes	J3103	"Invalid Cross-Reference Format"
Sun Blade 1000	Write-enable	No	J2103	"Invalid Cross-Reference Format"
Sun Fire V210	Write-protect	No	JP11	"Invalid Cross-Reference Format"
Sun Fire V240	Write-protect	Yes	JP11	"Invalid Cross-Reference Format"
Sun Netra 240	Write-protect	Yes	JP11	"Invalid Cross-Reference Format"
Sun Fire 280R	Write-enable	Yes	J2103	"Invalid Cross-Reference Format"
Sun Netra T4	Write-enable	Yes	J2103	"Invalid Cross-Reference Format"
Sun Fire V440	Write-enable	Yes	J4205	"Invalid Cross-Reference Format"
Sun Fire V480	Write-enable	Yes	J1104	"Invalid Cross-Reference Format"
Sun Fire V490	Write-enable	Yes	J1104	"Invalid Cross-Reference Format"
Sun Fire V880	Write-enable	Yes	J3003	"Invalid Cross-Reference Format"
Sun Fire V890	Write-enable	Yes	J3003	"Invalid Cross-Reference Format"

1. Halt the system by typing init 0 at the superuser prompt.

2. Power off the system.

Caution - Use proper grounding procedures, such as wearing an antistatic wrist strap to avoid electrostatically damaging system components.

3. If necessary, remove the system cover from the Sun Enterprise 250, Ultra Enterprise 450, Sun Fire V240, Sun Netra 240, Sun Fire 280R, Sun Netra T4, Sun Fire V440, Sun Fire V480, Sun Fire V490, Sun Fire V880, or Sun Fire V890 system (see the following note).

Note - Sun Enterprise 250, Ultra Enterprise 450, Sun Fire V240, Sun Netra 240, Sun Fire 280R, Sun Netra T4, Sun Fire V440, Sun Fire V480, Sun Fire V490, Sun Fire V880, or Sun Fire V890 servers: The default position for the write-protect/write-enable jumper on the motherboard is write-enable. Therefore, unless you have reset the jumper to the write-protect position at an earlier time, it is not necessary to remove the system cover before updating the flash PROM. Instead, set the front panel keyswitch to Power-On () and continue with the procedure in Chapter 2.

Note - Sun Blade 1000 and Sun Fire V210: The default position for the write-protect/write-enable jumper on the motherboard is in the write-enable position. Therefore, unless you reset the jumper to the write-protect position at an earlier time, it is not necessary to remove the access panel before updating the flash PROM.

4. Locate the flash PROM jumpers on the motherboard or system board in your system.

Refer to the table below to find the appropriate diagram for your system.

Sun Fire V890	"Invalid Cross-Reference Format"

5. Compare your system's existing jumper settings with the settings and functions described in "Invalid Cross-Reference Format".

6. If an installed plug-in card in your system covers the flash PROM jumpers, remove the card from the system before changing the desired jumpers.

Refer to your system's service or reference manual for instructions.

7. Use a pair of small needlenose pliers to move the jumper to the desired pins.

For systemss covered in this guide, you set the write-protect/write-enable jumper to write-enable by moving the jumper to pins 2 and 3 (see FIGURE 1-1).

FIGURE 1-1 Setting the Write-Protect/Write-Enable Jumper to the Write-Enable Position

Note - Sun Fire V210, Sun Fire V240, and Sun Netra 240 servers use a two pin jumper. When the jumper is fitted, it is in the write-protected position. When the jumper is not fitted, it is in the write-enabled position.

Note - When you are finished updating the flash PROM, return the flash PROM write-protect/write-enable jumper to the write-protect position to ensure system security. If your system is a Sun Enterprise 250, Ultra Enterprise 450, Sun Fire V240, Sun Netra 240, Sun Fire 280R, Sun Fire V440, Sun Fire V480, Sun Fire V490, Sun Fire V880, or Sun Fire V890, do not change the jumper; instead, return the front panel keyswitch to the Locked position ().

8. If you removed a plug-in card from the system before changing the jumper, replace the card now.

Refer to your system's service or reference manual for instructions.

9. Remove your wrist strap and if necessary, replace the system cover.
