RJ45 Serial Port Configuration
The RJ45 serial port connector can be configured to support either a DSR signal or a DCD signal. As the
server board is shipped, it is configured to support DSR signals. To change the configuration to support DCD
signals a jumper on the board must be changed. Use the following instructions to configure your server board
to support DCD signals.
1.
Turn off all peripheral devices connected to the server. Turn off the server.
2.
Disconnect the AC power cord from the server.
3.
Remove the server's cover.
4.
Locate the jumper block for the serial port.
5.
Move the jumper from the default position covering pins 1 and 3 to cover pins 2 and 4.
Password Clear Jumper
If the user or administrator password(s) is lost or forgotten, moving the password clear jumper (board location
J1H3) to the clear opsition will clear both passwords. The BIOS determines if the password clear jumper is in
the clear position during BIOS POST and clears any passwords if present. The password clear jumper must be
restored to its original position before a new password(s) can bes set. The password clear jumper is shown on
the line labeled "A" in the figure below.
1.
Power down the system and disconnect the AC power.
2.
Open the server chassis.
3.
Move the jumper from the normal operation positiion, Password Clear Protect, at pins1 nad 2 to the
Password Clear Erase position, covering pins2 and 3 as indicated in the following figure.
