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.
