S14 & PS14P (PoE) Convenient Switches
The DC power plug connector or "jack" is in the right rear of the chassis. The
internal DC input terminal block is also provided on the rear side of the unit.
2.4 Frame Buffering and Latency
The Magnum S14-Series & PS14P(PoE) Switches are store-and-forward
switches. Each frame (or packet) is loaded into the Switch's memory and inspected before
forwarding can occur. This technique ensures that all forwarded frames are of a valid
length and have the correct CRC, i.e., are good packets. This eliminates the propagation of
bad packets, enabling all of the available bandwidth to be used for valid information.
While other switching technologies such as "cut-through" or "express" impose
minimal frame latency, they will also permit bad frames to propagate out to the Ethernet
segments connected. This "cut-through" technique permits collision fragment frames,
which are a result of late collisions, to be forwarded which add to the network traffic.
