    3 SAFETY Read the installation instructions before connecting the chassis unit to the power source. Do not install the chassis unit with power on. The chassis is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security. Blank face plates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis, they provide electromagnetic interference shielding and they direct the flow of cooling air through the chassis.

    The 10G Probe supports both in-band management (i.e. using eth2 for both data/video and management) and separate management (i.e. using eth1 for management). In any case make sure that the subnets configured for eth2 and eth1 do not overlap – otherwise the probe will not work properly. Note that if IP-addresses for eth2 and eth1 are configured so that the subnets overlap, the IP-address of one of the ports will be automatically set to 1.1.1.1 by the 10G Probe.
