Operating Notes:
•
The USR4524 operates in aggregation mode, it is important to consider the link utilization on the network links. If the
combined bidirectional traffic over the network ports exceeds the speed of the monitoring devices, loss of the traffic through
the monitoring ports will occur.
•
At the default settings, the network ports on the USR4524 are set to 1G speed. If these ports are connected to networking
devices with manual speed settings, confirm that the devices on either side of the TAP are at the same speed. For optimal
results set all connected networking devices to AUTO speed negotiation.
•
For up to 1 Gbps speeds, use Cat 5 or better cable with a maximum length between
network devices (not including the TAP) of 100 meters.
•
The TAP ethernet ports use Auto-MDI/MDI-X, so either crossover cables or straight
cables may be used.
•
If power is lost on the USR4524, internal relays on the network ports will close
and allow traffic to continue to pass through. Monitor ports will not transmit traffic
while the device is powered off.
•
Supports jumbo frame sizes up to 9,216 bytes.
