3.4.1.4 BIOS Select Jumper
The jumper block at J1G1 is used to select which BIOS image the system will boot to.
Pin 1 on the jumper is identified with a “ ”. This jumper should only be moved if you
want to force the BIOS to boot to the secondary bank, which may hold a different
version of the BIOS.
The rolling BIOS feature of the server board automatically alternates the Boot BIOS to
the secondary bank if the BIOS image in the primary bank is corrupted and cannot
boot.
3.4.1.5 Serial B Port Configuration Jumper
The rear of the Carrier Grade Server TIGW1U provides an RJ45 connector for the Serial
B port, which is intended for direct connection to serial devices such as serial port
concentrators using a standard Cat 5 cable.
Serial devices that use RJ45 connectors differ in the signal they require on Pin 7. For
example, modems typically require the DSR signal, and serial concentrators may
require the DCD signal. Table 3 describes how to use jumper J2A2 to configure the
serial port to provide either of these two signals.
3.4.1.6 Processor Select Jumper
The server board is pre-configured for the Dual-Core Intel ® Xeon ® processor 5100
series, but the following server system product codes support both the Dual-Core
Intel ® Xeon ® processor 5100 series and the Quad-Core Intel ® Xeon ® processor 5400
series. These product codes have an “R in the third position.
• Kontron Carrier Grade Server TIGW1U. AC
• Kontron Carrier Grade Server TIGW1U. DC
If you have one of these products and you want to use a Quad-Core Intel ® Xeon ®
processor 5400 series, you must remove the jumper from pins 1-2 on the processor
select jumper. This jumper is located at position J3E2 on the server board. See the
following figure.
Table 3. Serial B Port Configuration Jumper
Jumper Name Pins Description of Configuration
J2A2: Serial Port
1-2
DCD (Data Carrier Detect) signal routed to Pin 7 of rear RJ45 Serial B
port connector. This configuration provides compatibility with Cisco serial
concentrators. (Default)
2-3
DSR (Data Set Ready) signal routed to Pin 7 of rear RJ45 Serial B port
connectors. This configuration provides compatibility with standard
modems.
Note: Bold entry in “Pins” column indicates default configuration.
