Fujitsu M2511A EXT

The M2511A EXT is a high performance 3.5 inch external optical disk subsystem for use on systems via the SCSI interface or via a converter attached to the parallel port of your PC or laptop. It contains a power supply which allows connection to 90 - 260 V a.c. mains supplies, a cooling fan and cleaning filter. Media complying to the ISO/IEC 110090 standard can be used, three types of media are supported, MO rewritable, O-ROM and P-ROM.

Power switch

This is located on the front fascia and is a latching push-button switch. Push once to power on the M2511A EXT, push again to power off.

Power LED

This green LED will illuminate if D.C. power is present in the M2511A EXT (i.e. if the power switch has been pushed). Please note that AC power will be present inside the M2511A EXT if the mains supply cable is installed and connected to a live mains socket.

Disk insertion slot

This is where optical disk media is inserted into the drive. For vertical orientation ensure that the disk label is to the left, and for horizontal orientation ensure that the disk label is facing up. Push the optical media fully in to enable loading.

Eject Button

Push this button to eject media from the drive. This electrical eject button is active only when the M2511A EXT is powered on. Please note that the operation of this button may be inhibited by system software.

Emergency eject hole

To be used to eject media when power has been lost. Insert the emergency eject tool supplied in the kit (a straightend paper clip will do) in this hole, and push to eject the media.

Drive activity LED

This green LED will illuminate whenever the optical drive is reading, writing or seeking.

SCSI ID select switch

Set the SCSI address of the M2511A EXT by use of the recessed + and - buttons. Use a pen or the emergency eject tool to adjust to match the system requirements. Default address is 4.

SCSI terminator

All SCSI busses need to be terminated at both physical ends. The M2511A EXT has a terminator fitted in the SCSI connector nearest the fan. If it is not the last physical device on the SCSI bus, remove this terminator.

SCSI connectors

The M2511A EXT has two Centronics type SCSI connectors. One for SCSI in and the second for SCSI out or temination. Either connector can be used for in or out.

A.C. power in

This is an IEC standard mains input plug. Connect the mains supply (90-260V) by pushing the corresponding connector of the mains cable supplied into this socket. To ensure safe operation, ensure that the mains cable is not connected to a live supply prior to installation.

Removable air filter element

The filter element cleans the cooling air supplied to the M2511A EXT by the fan. It should be removed and cleaned on a regular basis to ensure efficient air cooling. The filter cover can be easily removed by a small screwdriver or paper clip. To protect the optical drive from dust do not run with the filter element removed. Spare filters are supplied in the kit.

PC/Mac switch

For operation on IBM PC compatible machines, slide this switch to the PC position prior to powering on. For Apple Macintosh sytems place in the Mac position.
