(DDR4-1866), or PC4-17000 (DDR4-2133), DDR4 (fourth-generation
double-data-rate), synchronous dynamic random access memory (SDRAM)
DIMMs.
v Light path diagnostics
Light path diagnostics provides LEDs to help you diagnose problems. For more
information about light path diagnostics and the LEDs, see the operator
information panel or LCD operating panel assembly (see “Operator information
panel” on page 20 or“LCD operating panel assembly” on page 21.
v Mobile access to IBM Service Information website
The server provides a QR code on the system service label, which is on the
cover of the server, that you can scan using a QR code reader and scanner with
a mobile device to get quick access to the IBM Service Information website. The
IBM Service Information website provides additional information for parts
installation and replacement videos, and error codes for server support. For the
QR code, see QR code information on page Chapter 1, “The IBM System x3550
M5 server,” on page 1.
v Multi-core processing
The server supports up to two Intel Xeon
™
E5-2600 v3 series multi-core
microprocessors. The server comes with a minimum of one microprocessor.
v PCI adapter capabilities
The server has two PCI interface slots. See “Replacing an adapter” on page 180
for detailed information.
v Redundant connection
The addition of the optional Ethernet adapter 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
adapter is installed on the server, all Ethernet traffic that is associated with the
primary connection is automatically switched to the optional redundant Ethernet
adapter connection. If the applicable device drivers are installed, this switching
occurs without data loss and without user intervention.
v Redundant cooling and optional power capabilities
The server supports a maximum of two 550-watt, 750-watt, or 900-watt hot-swap
power supplies and seven or eight dual-motor hot-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 the minimum of one 550-watt, 750-watt, or 900-watt
hot-swap power supply and five or six fans.
You must install the fourth and sixth fans when you install the second
microprocessor in the server. You can order the second optional power supply
for power redundancy.
Note: You cannot mix power supplies that have different wattages in the server.
v 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.
v SD adapter
A raid controller for Secure Digital (SD) media. It has two upstream connections,
a USB connection to the server chipset, and an MMC connection to the
integrated management module (IMM2.1).
