Axis Rack Mounted Video Server Solution
Mounting AXIS blade video servers
The AXIS Video Server Rack can accommodate 3 Axis blade video servers. The slots for these are
numbered 1-3 from left to right, as seen from the front. The I/O connectors for each slot on the
rear panel are also numbered.
1. Remove a front panel cover from the slot in which the video server will be mounted. This is
done by unfastening the screw on each side of the cover.
2. Slide the video server into place, using the guides as an aid. The dip switch for setting the
line termination should be visible on the top edge.
3. Fix the video server in place, using the screws from the front panel cover.
Note:
Leaving an empty slot on the AXIS Video Server Rack open is not permitted.
Front panel covers must be used on all empty slots.
The I/O Terminal connector
The AXIS Video Server Rack server provides an I/O terminal connector for each Axis blade video
server (see illustration on page 4). This is used for connecting external equipment, in applications
for e.g. motion detection, event triggering, time lapse recording, alarm notification via email,
image storage to FTP locations, etc.
Connector interfaces
The interfaces available via the 12-pin I/O terminal connector are as follows:
4 Digital inputs - used for e.g. a pushbutton. If the button is pressed, the state changes and the input
•
will be active (shown under Event Configuration > Port Status).
4 Transistor outputs - for e.g. alarm devices that can be activated from Output buttons on the Live
•
View page, or as an action to an Event Type. The output will show as active (in Event Configuration
> Port Status) if the device is activated.
RS-485 interface, for e.g. Pan/Tilt/Zoom devices (see www.axis.com for drivers)
