Add-in Card Connectors
The Intel® Server Board SE7221BA1-E has the following add-in card connectors:
•
PCI Express* x8: one connector supporting simultaneous transfer speeds up to 8
GBytes/sec
•
PCI Express* x4: The board has two PCI Express* x4 connectors.
•
PCI Conventional (rev 2.2 compliant) bus: The SE7221BA1-E board has three PCI
Conventional bus add-in card connectors.
Note the following considerations for the PCI Conventional bus connectors:
•
All of the PCI Conventional bus connectors are bus master capable.
•
SMBus signals are routed to PCI Conventional bus connector 2. This enables PCI
Conventional bus add-in boards with SMBus support to access sensor data on the
Server Board. The specific SMBus signals are as follows:
⎯
The SMBus clock line is connected to pin A40.
⎯
The SMBus data line is connected to pin A41.
6.2 Jumper
Blocks
CAUTION
Do not move the jumper with the power on. Always turn off the power and unplug the power cord
from the computer before changing a jumper setting. Otherwise, the board could be damaged.
Figure 16 shows the location of the jumper blocks. The 3-pin jumper blocks determine the BIOS
Setup program’s mode. Table 22 describes the jumper settings for the three modes: normal,
configure, and recovery. When the jumper is set to configure mode and the computer is
powered-up, the BIOS compares the processor version and the microcode version in the BIOS
and reports if the two match. Table 23 describes the jumper settings for clearing CMOS.
