 Initial Configuration 

Working with SCSI Disks 

MGW 2400 requires a SCSI disk to save streams to file. MGW 
2400 is equipped with an Ultrawide SCSI port, which can 
connect to SCSI disks. 

To prepare and connect a SCSI disk: 

1.  Format the SCSI disk on a separate PC in NTFS or FAT 

(

not

 FAT32) format. If you wish, you can divide the SCSI 

disk into several partitions. 

2.  Create folders on the SCSI disk using the DOS-Shell 

command 

MD

. Copy clips to the SCSI disk. You may 

delete unused folders by using the DOS-Shell command 

RD

. 

3.  Make sure that MGW 2400 is switched off. 

4.  Connect the accordingly prepared SCSI disk to MGW 

2400’s SCSI port. 

5.  Switch MGW 2400 on again; MGW 2400 is now ready to 

transmit prerecorded clips. The SCSI disk's default drive is 
drive 

D

. Additional SCSI disk partitions are labeled in 

alphabetical order starting with drive 

E

. 

For instructions on sharing SCSI disk partitions, refer to 
page 42. 

Note 

Remember that you may log on to MGW 2400 from the Configuration PC via 

RS-232 or from any computer on the network via Telnet.
