ATTENTION

The protective cover must be fixed properly to ensure IP54

protection. Use a torque wrench set to a torque of 4 kgf-m when

tightening the screws. Note that applying a larger torque may

damage the plastic protective cover.

Bypass Relay Function

The TN-5510A-2GTXBP and TN-5510A-8PoE-2GTXBP models’ two Gigabit

Ethernet ports are equipped with a bypass relay function. When the

switch is operating normally, these two Gigabit ports work in the same

way as the other ports. That is, frame ingressions are processed and then

forwarded. In the event the switch stops working due to a power failure,

the bypass relay function will be triggered to ensure non-stop data

communication.

The figure below illustrates the bypass relay function. For example, if

Switch B loses power, then the two Gigabit ports will be bypassed through

the relay circuit and the transmission line from Switch A to B and the

transmission line from Switch B to C will interconnect automatically; this

way there is no stoppage.

The bypass relay function helps the network recover from single-node

failures in a linear topology.
