Server Installations and Upgrades—NSW1U Network Server
The jumpers that can be configured differently are:
• J2A2 (Serial Port B DSR/DCD jumper)
• J1H2 (Password Clear jumper)
• J1G1 (BIOS Bank Select jumper)
• J1F1 (CMOS Clear jumper)
• J1E3 (BMC Force Update jumper)
• J3E2 (Processor select jumper)
See Figure 10 for the location of these jumpers. The following sections give more detailed information
about the settings.
3.3.1.1 Jumper Blocks
The server board has several 2-pin and 3-pin jumper blocks that can be used to configure, protect, or
recover specific features of the server board. Pin 1 on each jumper block is denoted by an “*” or “ ”.
3.3.1.2 CMOS Clear and Password Reset Procedures
The CMOS Clear and Password Reset recovery features are designed to achieve the desired operation
with minimal system down time. The procedure is identical for these two features, but has changed
from previous generation server boards. The following steps outline the new procedure for both
operations.
1. Power the server down and remove the power cable. (Standby power is present on the server
board when power is turned off but still connected.)
2. Open the server.
