System x3750 M4 Types 8722 and 8733: Installation and Service Guide
optional Ethernet adapter is installed in the server, all Ethernet traffic that is
associated with the primary connection is automatically switched to an optional
Ethernet connection. If the applicable device drivers are installed, this switching
occurs without data loss and without user intervention.
The server comes with six dual-motor, counter-rotating, speed-controlled
hot-swap fans, which provide redundancy and hot-swap capability for a full
configuration. The redundant cooling by the fans in the server enables continued
operation if one of the fan motors fails.
The server comes with one 900-watt or one 1400-watt hot-swap power supply.
The server supports a maximum of two 900-watt or two 1400-watt hot-swap
power supplies. For redundancy support, two power supplies must be installed
in the server. Two power supplies enables continued operation if one of the
power supplies fails. You can order the optional IBM Power Interposer for
Redundant Power Option Kit or the optional IBM Microprocessor and Memory
Expansion Tray to install a second power supply.
The remote presence and blue-screen capture features are integrated functions of
the integrated management module (IMM). 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 IMM memory and mapping it to the server
as a virtual drive
The blue-screen capture feature captures the video display contents before the
IMM restarts the server when the IMM 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 136
for additional information.
A ServeRAID adapter provides hardware redundant array of independent disks
(RAID) support to create configurations. The server comes with an integrated
RAID controller, which provides RAID levels 0, 1 and 10. Additional optional
RAID adapters, RAID cache cards, and Features on Demand software RAID are
available for RAID levels 5, 6, 50, and 60 upgrade.
The server comes with an integrated management module II (IMM2). When the
IMM is used with the systems-management software that comes with the server,
you can manage the functions of the server locally and remotely. The IMM also
provides system monitoring, event recording, and network alert capability. The
systems-management connector on the rear of the server is dedicated to the
IMM. 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.
