• Hot-swap, redundant power supplies (optional)—Energy Star-compliant (80+Gold); up to
92% efficient
• Hot-swap, redundant cooling fans
Light Path Diagnostics
Light path diagnostics enables a technician to quickly identify and locate a failed or failing system
component, such as a specific fan or memory DIMM. This enables quick replacement of the
component, which helps increase server uptime and lower operating costs.
The front of the server has an LED indicator light to show possible component failures. If the front
LED indicates an error condition, by pressing a button on the front of the server an LED panel will
pop out and drop down for easy viewing without the need to open the server cover or remove the
server from the rack. The light path diagnostics panel tells the servicer which component requires
attention. In addition, many components have their own identifying LEDs. For example, each of
the memory modules has an LED next to the DIMM slot, as do all processors, all adapter slots, all
fans, the power supply, the voltage regulator modules and the service processor. This allows the
servicer to easily identify exactly which component needs servicing. By following the "light path,"
the component can be replaced quickly, and without guesswork. (Note: In the event of a failed
DIMM or processor, the system will restart and mark the component as bad while offline, thus
allowing the system to continue running, with reduced capacity, until serviced.)

Other Features

• Trusted Platform Module standard — This module provides a highly secure start-up process
from power-on through hand-off to the operating system boot loader. ACPI support is provided
to allow ACPI-enabled operating systems to access the security features of this module. (TCG
V1.2-compliant.)
• Five USB 2.0 ports — Provides flexibility to add high-speed external devices. The USB 2.0
specification supports up to 480Mbps transfer rates. (Note: Not all USB 2.0 devices are
capable of achieving this rate.) Two ports are provided on the front of the server, two are on
the back, and 1 is internal to support an optional flash memory key with embedded hypervisor.
• Toolless slides — Allows quick rack installation and quicker upgrade and servicing of the
server.
• Toolless chassis — The cover can be opened without tools, and many components can be
added or replaced without tools, including processors, DIMMs, hot-swap HDDs, PCIe
adapters, an optional optical drive, and the integrated or optional ServeRAID controller. This
can save a servicer significant time.
Advanced Systems Management Capabilities
The x3755 M3 has a high level of systems management capabilities that are well-suited to
remote locations as well as to stand-alone environments. Features include the UEFI, an
integrated Baseboard Management Controller
Systems Director Active Energy Manager, Automatic Server Restart, Wake on LAN support, PXE
support, text console redirect, Predictive Failure Analysis, and IBM Systems Director.
The iBMC provides industry-standard Intelligent Platform Management Interface (IPMI) 2.0-
compliant systems management. It provides a number of important system functions, including:
• Monitoring of system and battery voltage, system temperature, fans, power supplies,
processor and DIMM status
• Fan speed control
• Product ID and Family ID detection
• Highly secure remote power on/off
• System reset control
• NMI/SMI detection and generation
• System diagnostic LED control (power, HDD, activity, alerts, heartbeat)
• IPMI over LAN
• Serial Over LAN
• Proxy server support
• LAN messaging and alerting
• Text console redirection over LAN
• Predictive Failure Analysis for system fans
• Web-based out-of-band control
