Product Description

Package contents of the BayStack 60-12T/60-24T 10/100 Ethernet Hub include materials for rack mounting and connecting the hubs, such as a rack mount kit and an AC power cord. Standard Ethernet UTP or STP cables are not provided.

Autosense Capability

BayStack 60-12T/60-24T 10/100 Ethernet Hub ports automatically sense the 10 Mb/s or 100 Mb/s transmission speed of attached devices. Each port automatically sends traffic through the route with the highest available transmission speed, depending on the capability of the connected device. Traffic is forwarded to the 10 or 100 Mb/s segment on the hub, again depending on the incoming speed of the traffic. By confining traffic to its respective segments and only forwarding traffic to the other segment when required, the overall load on the network is significantly reduced.

Front Panel

The BayStack 60-12T/60-24T 10/100 Ethernet Hub includes front panel LEDs and ports for connecting to other devices.

Figure 1-1 and Figure 1-2 show the front panels of the BayStack 60-12T 10/100 Ethernet Hub and BayStack 60-24T 10/100 Ethernet Hub, respectively. Table 1-1 on page 4 provides further details about the LEDs.
