AXIS 291 1U Video Server Rack - Overview
Read the following information to familiarize yourself with the AXIS 291 1U Video Server Rack, making note
of where the connectors and indicators are located.
Power Connector - Input power: 100-240V AC, 50-60 Hz, 1.9A
I/O Terminal Connector(s) - provides the physical interface to the functions supported by the Axis blade video
server. For more information see page 8.
Network Connector - Axis blade video servers are designed for 10/100/1000 Mbps networks and are connected
via a standard RJ-45 connector.
Placement requirements
The location the AXIS 291 1U Video Server Rack is used in must meet the following requirements:
• Ambient temperature: 0°to +45°C (32°to 113°F)
• Relative humidity: 20-80%
• Power source within 1.8 meters
• Minimum 5cm free space on each side, to ensure adequate ventilation
• No excessive dust
Placement on a shelf/table
1. Attach the 4 rubber feet to the underside of
the unit, as illustrated here.
2. Place on a flat surface. Note that the AXIS
291 with cables can weigh up to 6kg. Check
that the surface can support this weight.

Installation in a 19” equipment rack
Requirements:
• Pozidriv screwdriver #1
• Pozidriv screwdriver #3
• The rack must be braced and bolted to the floor.
• The AXIS 291 must be grounded to the same ground as the equipment rack.
When mounting the AXIS 291 in a rack, never stack other units directly on top - the mounting brackets are not
designed to support more than 1 unit. Each unit in the rack must be secured with appropriate brackets. Place
the heaviest units at the bottom of the rack.
Attaching the brackets
The 2 mounting brackets are slightly different. To tell these apart, see the label on each bracket. See also the
illustration on page 3.
1. Remove the screw shown here
from each side of the unit. These
will be replaced by the screws
used to fasten the bracket.
2. Using the M3X8 screws, fasten the
bracket to the side of the unit. Do
not use the screw that was
removed in step 1.
3. Slide the AXIS 291 into the
equipment rack. Insert the M6X20
screws and tighten.

Connect power
Please ensure that the correct AC power cord for your country is used.
The AXIS 291 has no On/Off switch or button, and will power up as soon as the AC power cord is connected. It
is important to locate the unit so that the AC power cord is easily accessible. Detaching the cord is the only
way to remove power to the unit.
To prevent the risk of electrical shock when in contact with the unit casing, only earthed/grounded power
cords should be used to power the AXIS 291.
The AXIS 291 Video Rack Server is designed for use with Axis Blade Video Servers only.
If a foreign object is accidently dropped into the Video Rack Server, always disconnect power before
attempting to remove the object.
Power specifications
• Input voltage 100-240V AC, at 50/60Hz
• Input current: 1.9A
• Power consumption with 3 x AXIS 243Q: Max 80W
AXIS blade video servers
The S/N (serial number) is identical to the unit’s MAC/Ethernet address,
e.g. 00408C1A2B3C = 00-40-8C-1A-2B-3C. P/N is the product’s model number.
Bus Connector- This is the physical interface to the I/O terminal connector on the rack.
DIP Switches (4-port models) - Each video input has a corresponding line termination DIP switch. Axis blade
video servers are supplied with the line termination enabled for each input; that is, with the DIP switches set to
ON (down position).
To connect the video server in parallel with other equipment, disable the input termination by setting the
corresponding DIP switch to OFF (Up position). Failure to do so may affect the image quality negatively.

DIP Switches (1-port models) - These models can accomodate either composite or Y/C video. The type to use
is determined by the DIP switch settings. 1-port AXIS blade video servers are supplied configured for composite
video input, as shown in the table below.
Mounting AXIS blade video servers
The AXIS 291 can accomodate 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. If mounted, remove the front panel cover from the slot in which the video server will be mounted.
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.

The I/O Terminal connector
The AXIS 291 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 Configura-
tion > Port Status) if the device is activated.
•RS-485 interface, for e.g. Pan/Tilt/Zoom devices (see www.axis.com for drivers)
• Auxiliary power
Connector pinout
To connect input/output devices to the I/O terminal connector:
1. Referring to the table above, loosen the corresponding screw on top of the pin on the green connector
block.
2. Push the cable into the connector block and secure it by fastening the screw.
3. Once all devices are connected, push the connector block into the terminal connector on the rear panel of
the AXIS 291.
For compatible replacement connectors, contact http://www.phoenixcontact.com, quoting: MC1.5/12-ST-3.81
(art no 1803675).
