Product Overview Control • Fan control mode; system or power supply • Failure and Warning LED indication Intel® Server System SR1550AL Each power supply module operates within the following AC voltage ranges and ratings: PARAMETER Line Voltage (110) Line Voltage (220) Frequency MIN 90Vrms 180Vrms 47 Hz RATED 100-127 Vrms 200-240 Vrms 50/60Hz MAX 140Vrms 264Vrms 63 Hz Start-up Vac 85Vac ±4Vac - Power Off Vac 75Vac ±5Vac - Max Input AC Current 8.5 Arms1,3 4.2 Arms2,3 Notes: 1 2 3 4 Maximum input current at low input voltage range shall be measured at 90Vac, at max load. Maximum input current at high input voltage range shall be measured at 180VAC, at max load. This is not to be used for determining agency input current markings. Maximum rated input current is measured at 100VAC and 200VAC.

In addition, each power supply module includes a 56 mm dual rotor fan module which pulls air from inside the chassis and blows it out the back. Coupled with the onboard server management functionality of the server board, the cooling sub-system provides sufficient airflow to maintain internal system thermal requirements when the external ambient temperature remains within specified limits. Note: The cooling sub-system for this system provides no fan redundancy. Should any of the system fans fail, the system should be shut down as soon as possible to have the failed fan replaced. 1.9 System Security The system provides support for a lockable front bezel which prevents unauthorized access to the system control buttons and hard drives. In addition, a chassis intrusion switch is provided allowing server management software to monitor removal of the top cover from the chassis. 1.10 Rack and Cabinet Mounting Options The system was designed to support 19" wide by up to 30" deep server cabinets. The chassis supports three rack mount options: A fixed mount relay rack / cabinet mount, a tool-less sliding rail kit, or a basic three-quarter extension sliding rail kit. The fixed mount relay rack / cabinet mount kit can be configured to support both 2-post racks and 4-post cabinets. The tool-less sliding rail kit or basic rail kit is used to mount the chassis into a standard (19" by up to 30" deep) EIA-310D compatible server cabinet. An optional Cable Management Arm can be used with the tool-less sliding rail kit only. 1.11 Front Bezel Features The optional front bezel options are made of molded plastic and use a snap-on design with a key lock. When installed, the design allows for maximum airflow. 8 Revision - 1.3 Intel order number D31982-006
