A Jumper Setting ============== x = Jumpers set at factory J9, pins one through five, and J10 pins one through four, determine the disk drive operation modes. The jumpers are used primarily for isolation testing at the factory or authorized repair center. J2-1/3/4 CLOSED J2-2 OPEN J9 all OPEN J10 all CLOSED J11 CLOSED J2 Parity Option ---------------- x J2-1 CLOSED Enables odd parity detection in the disk drive. OPEN Disables odd parity detection in the disk drive. Odd parity is always generated by the disk drive and provided to the SCSI bus.

An ID of seven is the highest priority in a multidevice configura- tion, and is usually used for the initiator. The disk drive is shipped with an ID of six. This ensures that sufficient jumpers are available for any address except seven which is usually reserved for the host system.

A Interface Termination --------------------- SCSI devices require proper interface termination. The first device and the last device on the daisy chain SCSI bus must be terminated. Remove the terminators from any devices in between. For instance, if the disk drive is in the middle of the string, remove its terminators. As shipped, interface signal lines are terminated with three removable 220/330-ohm resistor network packs. The devices driving the disk drive inputs should be open collector devices capable of sinking at least 48 milliamps at a voltage of less than 0.5 volts DC (7438-type or equivalent). Devices receiving the disk drive outputs should be of SCHMITT trigger type to improve noise immunity (74LS14, 74LS240, or equivalent). The initiator should not load the bus with more than one standard low power Schotky transistor-transistor logic (LSTTL) input per line, and should terminate all signals with 220/330-ohm terminators. ********************************************************************** F E A T U R E S ********************************************************************** MAXTOR LXT 100S FAMILY PRODUCT SPECIFICATION 1018327, REV. A Self Configuration ------------------ When the disk drive powers up, or when it is reset, it configures itself using the parameters and information saved on the disk drive from the previous format operation. This includes the disk drive's exact model number returned in the INQUIRY command and parameters in the MODE SELECT pages of parameters. A UNIT ATTENTION condition is created for each initiator whenever the disk drive has been reset (by a BUS DEVICE RESET message or a RESET condition), or when the MODE SELECT parameters have been changed by other initiators. The UNIT ATTENTION condition persists for each initiator until that initiator issues any command (other than INQUIRY) which clears the UNIT ATTENTION condition. If an INQUIRY command is received from an initiator with a pending UNIT ATTENTION condition (before the disk drive reports the CHECK CONDITION status), the disk drive reports any pending sense data and preserves the UNIT ATTENTION condition. If a REQUEST SENSE command is received from an initiator with a pending UNIT ATTENTION condition (before the disk reports the CHECK CONDITION status), the disk drive reports any pending sense data and preserves the UNIT ATTENTION condition in the sense data. The CHECK CONDITION, however, is cleared and a GOOD status is returned on any subsequent command. Any subsequent command then clears the UNIT ATTENTION condition from the sense data.
