If the filter looks dirty, use the following procedure to replace the filtering screen: 1 Loosen the 8 captive screws which secure the front panel to the fan tray.
Plenums 51 Plenums Plenums facilitate proper air flow through the system by guaranteeing the minimum space necessary for proper system ventilation. The ADC plenum utilizes a single design that allows it to function in both an intake and exhaust capacity. When functioning in an intake capacity, the plenum is placed below each fan tray in the rack. When functioning in an exhaust capacity, the plenum is placed directly above the chassis.
CHAPTER 1: HARDWARE OVERVIEW A filtering screen is placed immediately behind the vented front panel to clean the incoming air stream prior to circulation up through the system. Replacement filters are available through ADC. When serving as an exhaust plenum, the fan trays mounted directly below each chassis push air up through the rack-mounted systems and into the exhaust plenum. The first chassis installation requires two plenums; one directly above the chassis, and one below the fan tray.

You must first access the system through these COM ports to assign an IP address to the Craft port and configure the system for network access. Both COM port 1 and COM port 2 provide serial access to the system. The advantage to this form of direct access is that you do not loose your connection to the system upon reboot.

C MARTEK POWER SUPPLY ADC offers an optional power supply that can be used to power the Cuda 12000. The power supply system offered by ADC is the Martek power supply model PS2266 and bay model B2266. Additional information and specifications can be obtained from the Martek Web site at: http://www.martekpower.com. WARNING: High voltage power supplies are extremely dangerous and should only be handled by a qualified electrical technician. Injury or death may result from improper handling.
APPENDIX C: MARTEK POWER SUPPLY LED Description Yellow LED Designed so that it will always be the opposite of the green LED. If the output voltage is above 40Vdc (+/- 5%) the yellow LED should be off. If the output voltage is less than 40Vdc (+/-5%) the yellow LED should be on. The LEDs are wired to the same logic as the DC_OK signal. Therefore, if the DC_OK signal (normally high) is high the Green LED will be on and the yellow LED will be off.
Basic Troubleshooting 143 3. A PS2266 module may be shorted internally, and therefore would cause the entire power supply chassis to short. Try installing one module at a time and check for voltage output after each one is installed. Note: Each of the four PS2266 modules delivers 1000 watts max (53Vdc @ 19 amps). The power supply chassis with all four power supply modules in and powered on provides 4000 watts.
