Installing the server Connecting devices to the server
Ê Connect the data cables to the devices and the server.
I Some of the connected devices require that you install and configure
special software (e.g. drivers) (see the documentation for the connected
device).
If you are using a separate graphics card in a slot, the graphics controller on the
system board is automatically deactivated. The corresponding monitor port
(SVGA) cannot be used. Instead, connect the data cable of the monitor to the
monitor port of the graphics card.
3.5.2 CAN bus connection
Several servers and storage subsystem (e.g. PRIMERGY S40-DF) can be
combined to form a group (functional unit, family/cluster). All the devices in a
group are assigned the same group ID but different device IDs. This ID (CAN
bus address) can be used to address each device using the communications
bus (CAN bus). A maximum of ten groups can be set up on one communica-
tions bus. All the devices in a group must be connected to the same CAN bus.
The CAN bus is a cable connection. The CAN bus must be terminated, i.e.
terminating resisters must be attached to free ends.
The server includes a PCI CAN bus controller (figure 11 on page 30), which
enables communication with a PRIMERGY S40-DF in a cluster configuration.
Communication between the PCI CAN bus controller and the storage
subsystems is enabled with the help of the ServerStart CD:
