2-42 General Description

Floppy Disk Drive

A USB floppy disk drive is attached to the main unit. It allows you to read and write (save) data using floppy disks.

The USB floppy disk drive accepts the following types of floppy disks:

2HD floppy disk (1.44MB) 2DD floppy disk (720KB)

Drive letter of floppy disk drive

The drive letter will change when the primary PCI module is switched to the standby PCI module while the Windows operating system is in operation. The drive letter of the floppy disk will be determined as follows:

“A” will be assigned to the floppy disk drive for the PCI module that is operating as the primary PCI module during Windows operating system boot-up. “B” will be assigned to the floppy disk drive for the standby PCI module.

Ex) If a floppy disk drive was connected for the first time while the primary PCI module is group 1.

Primary PCI module

 

PCI module (for group 1):

A drive

PCI module (for group 2):

B drive

IMPORTANT: In the event that the active PCI module switches to the standby PCI module due to a failure while the system is in operation, the floppy disk drive letter will change at the point PCI module switches to the standby module.
