Search Tips...

Keyword Search
Our search engine uses any or all keywords typed in the text box to give you product search results.
For instance, typing in kvm will give you a broader set of results than kvm switch cables.

Note, however, that keywords in quotes are treated as a single phrase and will not be evaluated individually.

Booleans (AND, +, OR, NOT, -) are not supported.

Also, some keywords will not return results, and may automatically correct to a similar keyword.

Part Number Search Selection
Select this Search in the drop down box to search by part number instead of keywords.

Wild Card Search
The * character is only supported in a limited capacity. Using whole words is the best approach whenever possible.

"New Search" Radio Button
Search the entire section that you are currently in.

"Search Within Results" Radio Button
Enter keywords or a part number to limit your results within the previously searched results.


Other features

A list of all matching product categories or resources will appear in the upper left corner of the results page, when applicable, to help you further narrow your results, if you desire.

Use the "sort by" drop-down menu on the results page to sort by "most popular" and price (low to high or high to low)
in the store section.

    • Description

    Dual-Speed 10/100 Stackable Hubs, 8-Port Desktop, Master


    Quick Facts

  • Each hub provides 8 or 16 autosensing RJ-45 ports.
  • Stack up to four 8-port desktop hub models to support up to 32 dual-speed ports.
  • Stack up to three 16-port rackmount units to support up to 48 dual-speed ports.

    • Further Details

  • Includes stacking cable, internal power supply, cooling fan, and metal brackets.
  • Comply with 10BASE-T and 100BASE-TX Ethernet standards.
  • The 16-port models can also be stacked with Mixed-Media Fiber Hubs (LH8050A).

    BLACK BOX® Dual-Speed 10/100 Stackable Hubs combine high-bandwidth 100-Mbps network devices with those running at 10 Mbps. Each hub provides 8 or 16 RJ-45 autosensing ports for 10- or 100-Mbps Ethernet, so each port can change speeds as needed to match the speed of a connected device.

    Master Hubs (LH8000A-M and LH8016A-M) include built-in switching that forwards packets between 10- and 100-Mbps domains. You only need one Master Hub to support additional Client Hubs in a stack, and you can position the Master Hub at any point in the stack. Unlike Master Hubs, Client Hubs don’t include a bridge module, so they cost less, and you save BIG!

    You can also stack and use the Client Hubs without a Master Hub:
    • If an Ethernet switch is available to interconnect the two speed domains.
    • If only 100-Mbps devices are connected and the 10-Mbps domain is unused, or vice versa.
    • If the application requires dual-speed operation with two unconnected and uncoordinated domains.

    In addition, the 16-Port Dual-Speed 10/100 Stackable Hubs can be stacked with Mixed-Media Fiber Hubs. The LH8016A-M is compatible with the Mixed-Media 16-Port Add-On Chassis (LH8050A-C), and the LH8016A-C is compatible with all five models of the Mixed-Media 16-Port Base Chassis (LH8050A). (In mixed configurations, your stack must have either a Master Hub or a Base Chassis.)

    Each Client Hub comes with a 9“ (22.8-cm) stacking cable with a 50-pin SCSI male connector. Just plug in the cable to connect your hubs and go!

    Address tables in both models have the capacity for up to 8000 node addresses, and all units comply with 10BASE-T and 100BASE-TX Ethernet standards.
