Table 6 gives the possible configuration options. This jumper should only be moved if
you wish to force the BIOS to boot to the secondary bank, which may hold a different
version of BIOS.
The rolling BIOS feature of the baseboard automatically alternates the Boot BIOS to
the secondary bank in the event that the BIOS image in the primary bank is corrupted
and cannot boot for some reason.
Note: When performing a BIOS update procedure, the BIOS select jumper must be set to its
default position (pins 2-3).
3.4.1.3 DCD/DSR Signal Select Jumper
Note: This jumper affects the rear panel serial port only.
Various serial port concentrators may require either the DCD (Data Carrier Detect) or
DSR (Data Signal Ready) signal on Pin 7 of the RJ45 connector. To allow support for
either of these two serial port configuration standards, a jumper block (J8A3) located
directly behind the rear RJ45 serial port (see Figure 19 ) must be configured
appropriately according to the desired standard:
• For configurations that are compatible with Cisco serial concentrators and require a
DSR signal, the jumper block must be configured with the serial port jumper over
pins 3 and 4. This is the factory-installed default setting for this jumper.
