OCPRF100 MP Server System Technical Product Specification
Revision 1.0
The PHP mechanism is a rotating part that actuates a switch located on the PHP board. There are four light emitting diodes (LEDs) per slot--two can be viewed from the rear of the system and two from inside the system. Once the LED shows which slot is powered down, the PHP mechanism can be depressed on the PHP actuator and the mechanism can be rotated out of place to remove the PCI card. Once the new PCI card is installed, rotate the PHP mechanism back into place to activate the switch and secure the PCI card.

2.11 Power Supply
The OCPRF100 MP server system power supply operates at 208 - 220 Vac, or 100 - 115 Vac is rated at 750 watts, and is designed to be hot-swappable, with a 2+1 redundancy factor. Each power supply has indicators showing correct operation, failure, and predictive failure. A power supply displaying the predictive failure LED still will operate corectly, but needs to be sent out for repair as quickly as possible. The predictive failure feature is designed to warn the operator of an impending power supply failure.
2.12 OCPRF100 MP Server System Chassis
The system chassis is the rack-mount chassis used in the system. The system chassis is designed to house all of the components listed above within a 7Ux 32” (+/-) deep space, and mount in a 19-inch rack. The chassis itself is 28” deep with the extra 4” to account for cable man- agement. The chassis was engineered to provide easy access to perform maintenance, upgrades, add memory, and add or remove PCI cards.
The functional server weighs between 120 and 140 pounds, depending on internal configura- tions. The chassis is designed to provide adequate thermal cooling of all devices within an ambient temperature of 10° to 40°C, while maintaining noise levels below 57 dB. If the ambient temperature exceeds 30°C, the fans in the fan bay will switch to high speed, cooling the system to operational values. Server management will log that a thermal excursion has occurred. Several internal heat sensors will monitor the temperature at key points inside the server. Should any of these sensors indicate that the temperature has exceeded a critical thermal set-point, server management will log the event, and the server will be shut down gracefully, according to user setup.
