1G Variable 4 Port Aggregator & Regenerator
USR4504 - Installation Guide
Installation Notes:
•
Before setting the USR4504 to “3 IN 1 OUT” mode, it is important to consider the link utilization on the ports 1, 2, and 3. If the combined
traffic over these ports exceed the speed of the monitoring devices, loss of traffic through the USR4504 ports will occur.
•
All ports on the USR4504 are set to AUTO speed negotiation. If these ports are connected to devices with manual speed settings, confirm
that the devices on the either side of the tap are at the same speed. For optimal results set all devices to AUTO speed negotiation.
•
It is recommended that the endpoint devices connected to each network port are capable of the same maximum speed. Oversubscription
may occur if the speeds are mismatched.
•
MDI-X may need to be turned off on some network devices connected to the tap for proper communication.
•
Power supplies should be connected to outlets with different circuit breakers to maintain maximum uptime.
•
The maximum cable length between network devices (not including the tap) should be 90m
•
Rack mount USR4500-RMK is available separately to mount 3 units horizontally.
