Chapter 2 Rack Cabling References • Ensure the monitor cables and mouse cables are long enough to allow the NetServer to be extended at the same time the keyboard tray is pulled out. Use locally available extensions if necessary. • The mounting distances provided in rack configuration tools assume cables between the servers and connected devices provide for the Cable Management Arm (for the LH 3000r). Cooling Requirements for the LH 3000r For optimum operational results, the HP NetServer LH 3000r should be kept at an operating temperature between 68 and 72 degrees F. Minimally, the interior of the NetServer must be kept between 41 and 95 degrees F, 5 - 35 degrees C. Remember that ambient temperatures may be lower than the temperature inside the server. Because of the heat generated by the HP NetServer LH 3000r, both the front and rear doors of the rack must have perforated surfaces. (Alternatively, both front and rear doors can be left off the rack.) Air flow in racked units flows through front and rear. If you are installing the HP NetServer LH 3000r in a rack that has solid front and rear doors, you must either replace the doors on your rack with perforated doors or remove solid doors to ensure proper air flow. Because of the high capacity fans installed in the HP NetServer LH 3000r, no external (rack) exhaust fan is needed with this unit. The rack must have perforated front and rear doors, or no doors. 30
