General Placement Requirements
•
•
•
•
Power source within 1.8 meters.
There must be a minimum of 5 cm free space on the bottom, front, rear and on both
sides of the AXIS Q7920 to ensure adequate ventilation.
Do not stack other units or objects directly on top of the AXIS Q7920. The mounting
brackets are not designed to support more than 1 unit.
No excessive dust.
Connect Power
The AXIS Q7920 has two On/Off switches. To switch off power to the AXIS Q7920 both power
supplies must be switched off.
Before switching on power to the AXIS Q7920, make sure the unit is properly grounded by using
the grounding screw.
Ensure that the correct AC power cord for your region is used.

AXIS Q7920 Chassis
WARNING
• 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 Q7920.
• If a foreign object is accidently dropped into the video encoder chassis, always disconnect
power before attempting to remove the object.
Axis video encoder blades
S/N — (Serial Number) is identical to the units MAC/Ethernet address.
P/N — is the products model number.
Bus Connector — This is the physical interface to the I/O terminal connector on the chassis.
Mounting Axis video encoder blades
The AXIS Q7920 can accommodate 14 Axis video encoder blades. The slots for these are numbered
1–14 from left to right. There are 4 slot groups in AXIS Q7920. Slot 1–4, slot 5–7, slot 8–11
and slot 11–14
The first blade should be inserted in slot 1. After that all slots can be used without any further
regulations. See Optimizing Performance, on page 15 for information of how to optimize the
performance of the AXIS Q7920.
In order to get full functionality from AXIS Q7920 the blade in slot 1 should be an AXIS Q7436,
AXIS Q7404, AXIS Q7414, AXIS P7224 or newer.
Follow these steps to mount an Axis video encoder blade in the AXIS Q7920:
1. Remove the front panel cover from the slot in to which the video encoder blade will be
mounted.
2. Slide the video encoder into place , using the guides as an aid.
3. Fix the video encoder in place, using the screws from the front panel cover.
The AXIS Q7920 supports hot-swap of video encoder blades. A blade can be removed and/or
inserted without the need of switch off the AXIS Q7920.
NOTICE
Front panel covers should be used on all empty slots.

The AXIS Q7920 supports hot-swap of a fan tray. A fan tray can be removed and/or inserted
without the need of switch off the AXIS Q7920.
Optimizing Performance
Firmware Upgrade
The AXIS Q7920 has an automated built-in function for firmware upgrade. If a blade that is inserted
in slot 1 in the AXIS Q7920 contains a newer firmware than the current one in AXIS Q7920. The
AXIS Q7920 will automatically be upgraded to the new firmware version. The upgrade may take up
to one minute to accomplish.
Network Redundancy
The network redundancy in AXIS Q7920 is controlled by software and requires that at least two
network connectors (either RJ45 or SFP) are connected. There are four uplink groups in AXIS Q7920,
each with a SFP and a RJ45 connector. The SFP connector has priority over the RJ45 connector.
In case of a malfunction in a connection the AXIS Q7920 will check for a connection in the
same uplink group or if needed check for a connection in another uplink group until a network
connection can be established.
Hot-swap
The AXIS Q7920 supports hot-swap of blades, fan tray and PSU. They can be removed and/or
inserted without affecting operation of the AXIS Q7920.
Rack Monitoring Daemon
In order to use the rack monitoring daemon function, the blade inserted in slot 1 must be an
AXIS Q7436, AXIS Q7404, AXIS Q7414, AXIS P7224 or newer.

ENGLISH
Follow these steps to replace a fan tray.
AXIS Q7920 Chassis
Maximum network output
In order to optimize the network performance of the AXIS Q7920 activate as many uplink groups as
possible (either RJ45 or SFP). Spread the blades evenly among the slot groups.
For every slot group activated an uplink group should be activated. See below for the connection
between slot groups and uplink groups.
Slot group 1: Slot 1–4. Uplink group 1
Slot group 2: Slot 5–7. Uplink group 2
Slot group 3: Slot 8–10. Uplink group 3
Slot group 4: Slot 11–14. Uplink group 4
