With the maximum segment length of category 5 twisted-pair cable being
100 meters, cable length must be considered when designing a network
that utilizes this function. For example, the total length of the cables from
Switch A to B and from B to C must be no more than 100 meters. This way,
if the two adjacent nodes (switch B and C for example) encounter a power
failure, there will be no stoppage, provided that the total length of the
cables A-to-B, B-to-C, and C-to-D are no more than 100 meters.
The bypass relay function works best for networks with linear topologies.
ToughNet™ switches with bypass relay function are not recommended to
be used in networks that employ ring topologies because network loops
may occur when redundancy protocols such as RSTP or TurboRing™ are
applied.
LED Indicators
Several LED indicators are located on the ToughNet switch’s front panel.
The function of each LED is described in the table below.
