As shipped by the factory, these jumpers are configured for zero delay. During applica- tion testing, Maxtor has found that many controllers require some delay. Maxtor recommends trying 533ns. There is no risk of data corruption, however RECORD NOT FOUND errors may occur in testing various settings.

If JP6 is in, ignore this column. This table applies only to drives with firmwate revision level M2.2 and higher. JP14 Write Protect Selection Jumper ----------------------------------- Jumper JP14 is the write protect jumper. When the jumper is present (installed), the drive is write protected and can only be read; no writing can take place. As shipped from the factory, jumper JP14 is removed. JP6 Sequential Spindle Motor Spinup Jumper ------------------------------------------ The spindle motor spinup jumper allows a string of drives to be started sequentially be the controller. When the jumper is present (installed), the drive automatically pins up as soon as power is applied. If JP6 is removed, the drive is started by issuing the appropriate command from the controller. As shipped from the factory, jumper JP6 is installed. JP16-JP29 Hard Sector Configuration Jumper ------------------------------------------- JP31 selects the mode of operation. When JP31 is installed, it configures the drive as a soft sector drive; when removed, it configures the drive as a hard sector drive. Jumper JP16 through JP29 allow the user to configure the drive's hard sector size. The sector size can range from a minimum of 123 to a maximum of 31,410 unformatted bytes per sector, with 1 byte granularity. The hard sector configuration jumpers are encoded in a binary fashion, with JP16 being the least significant byte and JP29 being the most significant byte. An installed jumper selects the binary value. Jumper JP30, if installed, enables setting the hard sector size over the ESDI. The drive must be in hard sector mode (i.e. JP31 removed).

Mounting -------- The XT-8000E may be mounted in any orientation. In any final mounting configuration, ensure that the operation of the three shock mounts which, isolate the base casting from the frame is not restricted. Certain switching power suppplies may emanate electrical noise, which can degrade the specified read error rate. For best results, orient the drive so that the PCB assembly is not adjacent to these noise sources. Mounting Holes -------------- Eight mounting holes, four on the bottom and two on each side, are provided for mounting the drive into an enclosure. The size and location of these holes are identical to industry standard floppy drives. Caution: The casting is very close to the frame mounting holes in some locations. Mounting screws lengths must be chosen such that no more than 0.125 inch of the screw is available to enter the frame mounting hole. The torque applied to the mounting screws must be between 9 and 12 inch pounds. Installation Requirements ------------------------- The XT-8000E must operate in a temperature range between 50*F and 122*F (10*C and 50*C). The drive should be installed in applications where temperature extremes outside of this range are avoided. To maintain proper operating temperature, the XT-8000E must be mounted in such a way as to ensure adequate airflow. Caution: These requirements must be met to ensure proper functioning of the drive. If they are not met, data loss and/or permanent damage to the drive will result. J1/P1 Connector --------------- Connection to J1 is via a 34-pin OCB edge connector. The pins are numbered 1 through 34 with the even pins located on the component side of the PCB. Oin 2 is located on the end of the PCB connector closet to the DC power connector J3/P3. A key slot is provided between pins 4 and 6. The recommended mating connector for P1 is AMP ribbon connector, P/N 88373-3. J2/P2 Connector --------------- Connection to J2 is via a 20-pin PCB edge connector. The pins are numbered 1 through 20 with the even pins located on the component side of the PCB. The recommended mating connector for P2 is AMP ribbon connector, P/N 88373-6. A key slot is provided between pins 4 and 6. J3/P3 Connector --------------- The DC power connector, (J3), is a 4-pin AMP MATE-N-LOCK connector, P/N 350543-1 mounted on the solder side of the PCB. The recommended mating connector (P3) is AMP P/N 1-480424-0 using AMP pins P/N 350078-4 (strip) or P/N 61173-4 (loose piece). J4/P4 Frame Ground Connector ---------------------------- The frame fround connector is a Faston type connector, AMP P/N 61761-2. The recommended mating connector is AMP P/N 62187-1. If wire is used, the hole in J4 will accommodate a maximum wire size of 18 AWG. Normally, this connector is not used. J6/P6 Auxiliary Connector ------------------------- The auxiliary connector is a Berg 68451-121, 10 pin connector. The mating connector is a 3M 3473-6010 connector. Removable Faceplate ------------------- The faceplate may be removed in installations where it is not required. Remove the two e-clips and unplug the LED cable from the PCB. ********************************************************************** F E A T U R E S ********************************************************************** MAXTOR XT-8000E FAMILY QUICK REFERENCE GUIDE 1018330 REV.
