The server has six PCI interface slots. Slot 1 can support PCI Express or PCI-X adapters through an
optional PCI-X interposer card. See “Installing an adapter” on page 216 for detailed information.
•
Redundant connection
The addition of the optional Ethernet daughter card provides failover capability to a redundant Ethernet
connection with the applicable application installed. If a problem occurs with the primary Ethernet
connection and the optional Ethernet daughter card is installed on the server, all Ethernet traffic that is
associated with the primary connection is automatically switched to the optional redundant Ethernet
daughter card connection. If the applicable device drivers are installed, this switching occurs without
data loss and without user intervention.
•
Redundant cooling and optional power capabilities
The server supports a maximum of two 750-watt or 900-watt hot-swap power supplies and six
simple-swap fans, which provide redundancy and hot-swap capability for a typical configuration. The
redundant cooling by the fans in the server enables continued operation if one of the fans fails. The server
comes with one 750-watt or 900-watt hot-swap power supply and two fans.
You must install fan 2 when you install the second microprocessor in the server. You can order the
optional fan 4, 5, and 6 for cooling redundancy. You can order the second optional power supply
for power redundancy.
Notes:
1. You cannot mix 750-watt and 900-watt power supplies in the server.
2. The server is not running in power redundant mode with two 225W GPUs installed, two 900-watt
power supplies are required.

Remote presence and blue-screen capture features
The remote presence and blue-screen capture features are integrated functions of the Integrated
Management Module II (IMM2). The remote presence feature provides the following functions:
– Remotely viewing video with graphics resolutions up to 1600 x 1200 at 75 Hz, regardless of the system
state
– Remotely accessing the server, using the keyboard and mouse from a remote client
– Mapping the CD or DVD drive, diskette drive, and USB flash drive on a remote client, and mapping ISO
and diskette image files as virtual drives that are available for use by the server
– Uploading a diskette image to the IMM2 memory and mapping it to the server as a virtual drive
The blue-screen capture feature captures the video display contents before the IMM2 restarts the server
when the IMM2 detects an operating-system hang condition. A system administrator can use the
blue-screen capture feature to assist in determining the cause of the hang condition.
See “Using the remote presence and blue-screen capture features” on page 115 for additional information.

ServeRAID support
The ServeRAID adapter provides hardware redundant array of independent disks (RAID) support to
create configurations. The standard RAID adapter provides RAID levels 0, 1, and 10. An optional RAID
adapter is available for purchase.
•
Systems-management capabilities
The server comes with an Integrated Management Module II (IMM2). When the IMM2 is used with the
systems-management software that comes with the server, you can manage the functions of the server
locally and remotely. The IMM2 also provides system monitoring, event recording, and network alert
capability. The systems-management connector on the rear of the server is dedicated to the IMM2. The
dedicated systems-management connector provides additional security by physically separating the
management network traffic from the production network. You can use the Setup utility to configure the
server to use a dedicated systems-management network or a shared network.
