## VMU-HD (ROF 157 5126/_)

To install unpack the VMU-HD board with the mounted hard disk. The Flash disks are available with a capacity of 60 MB. Remove the transport protection for the hard disk and keep it in case of re-shipment e.g. factory repair. Install and configure the VMU-HD in the cabinet according to the stipulations in Start Of Operation (1537-ASB 150 02 Uen).

Note

The VMU-HD will not start up without internal directories created on the hard disk.

#### DIP switches

DIP switch 990 selects whether register function is enabled or not.

990/1 | 990/2 | Function
OFF | ON or OFF | 16 channels, no register function
ON | OFF | 8 channels with MFC detection and DTMF / Tone receiver
ON | 8 channels with MFE detection and DTMF / Tone receiver

#### Flash disk (prior Hard disk)

The Flash disks will already be pre-configured in the factory with announcements and voice prompts in the proper language (related to the country which has placed the order).

The announcements and the voice prompts can always be adapted according to the customer needs, see document BusinessPhone 250/50 VMU-HD & MFU (1553-ROF 157 5126 Uen).

In case you need another language version than the pre-configured one, please contact your local Ericsson Support Centre

The directory structure on the Flash disk looks as follows:

    \Info0    \message2    \anno0
    \Info1    \message3    \anno1
              \message4    \anno2
              \message5    \anno3
                            :
                         \annoF

To modify the files on the Flash disk use a PC with a PCMCIA drive.

#### Limitations

Only one VMU-HD ( with a PCMCIA Hard disk) can be mounted per cabinet and just one type either VMU-HD or VMU-D can be installed in a system.
