Pinset 6 has no effect if Sync Mode is disabled. Refer to Mode Page 04H. Do not short this pinset. Pinset 6, rear pin, provides a ground connection for external cabling. 9 Auto Spin-up --------------- 9 OPEN Drive will not spin up until Initiator sends Start Unit command 9 CLOSED Drive will spin up automatically at Power-On 10 Parity --------- 10 OPEN Inhibit parity checking 10 CLOSED Enable parity checking 11 SDTR -------- 11 OPEN Inhibit drive Initiation of SDTR message 11 CLOSED Enable drive Initiation of SDTR message at Power-On and Reset. 12 Unit Attention ----------------- 12 OPEN Enable Unit Attention 12 CLOSED Inhibit Unit Attention 13 Write Protect ----------------- OPEN Drive looks at Mode Page Header and responds accordingly; default = NOT write protected CLOSED Drive is forced into the Write Protect mode 14 Reserved ------------ MUST BE OPEN! ********************************************************************** I N S T A L L ********************************************************************** HEWLETT HP C2490A INSTALLATION GUIDELINES 5961-4360 10/1993 Notes on Installation ===================== Screws ------ Maintain a minimum clearance of 0.06 in. (1.5mm) between any system structure and the top and all four sides of the disk drive. Insure that the system structure contacts only the drive mounting frames and clears the drive HDA by at least 0.06 in. (1.5mm). Maintain a minimum clearance of 0.04 in. (1.0 mm) between any system structure and any PCA component. Use 6/32 UNC screws with flat washers under the heads and torque them to 15 inch-pounds. When mounted, the screw should not protrude more than 6 mm (0.24in.) into drive from mounting frame surface. Operating Temperature Guidelines -------------------------------- Ambient air temperature and airflow must be properly balanced to maintain drive performance and reliability. Operating Temperature Considerations The operating ambient air temperature specification is 5*C to 50*C (41*F to 122*F). Adjust the ambient air temperature to prevent the temperature at each location from exceeding the stated limit. Airflow Considerations The recommended air flow to maintain the component temperatures is 3 to 5 CFM (cubic feet per minute) with most of the air flowing across the printed circuit board. Adjust the air flow to prevent the temperature at each location from exceeding the stated limit.
