Ambient temperature ------------------- The operating temperature range of the drive is specified at a dis- tance of 3 cm from the drive. Multi-drive connection ---------------------- In serial mode, up to 7 drives can be connected. The termination of the control signals must be performed only at the last drive. The terminator must be removed from all but the last drive. To connect drives, the A cable (control signals) must be connectesd in series and the B cables (R/W signals) in parallel. +----------+A cable A +---------+ | +-----------*------+ Drive 1 | | C |B cable | B | | | O +-----------|------+ | | N | | +---------+ | T | | | R | | A +---------+ | O | *------+ Drive 2 | | L |B cable | B | | | L +-----------|------+ | | E | | +---------+ | R | | | | | | | | A +---------+ | | +------XXX TERM | | |B cable B | | | +------------------+ Drive n | | | +---------+ +----------+ Cable length should not exceed 3m! AC line noise ------------- To eliminate AC line noise, a noise filter of the specifications given below should be incorporated in the AC input terminal of the drive power supply. Attenuation characteristics: 40 dB or greater at 10MHz Mean Time Between Failures (MTBF) --------------------------------- The estimated MTBF of the drive during its life time is 30.000 hours after an initial 3-month period. Mean Time To Repair (MTTR) -------------------------- MTTR is the average time taken by a well-trained service mechanic to diagnose and repair a drive malfunction. The drive is designed for a MTTR of 30 minutes or less. Service life ------------ Overhaul of the drive is not required for the first five years. Power loss ---------- Integrity of the data on the disk is guaranteed against all forms of abnormal power failure except a power failure during writing. ********************************************************************** F E A T U R E S ********************************************************************** FUJITSU M2247E/M2248E/M2249E OEM MANUAL 41FH5015E-02 Media defects ============= Cylinder 0, Head 0 and 1 are defect free.
