The SuperStack® II Dual Speed Hub 500 is an easy-to-use, 10/100

autosensing manageable and stackable hub (repeater). It is ideal for

users that want the power of Fast Ethernet and the flexibility to connect

10Mbps devices (workstations and other equipment) in the same hub or

stack.

The Dual Speed Hub 500 has 12 or 24 shielded RJ45 10/100 autosensing

ports on the front panel which can both be used to connect 10BASE-T

(Ethernet) or 100BASE-TX (Fast Ethernet) devices to the hub. There are

two segments (10Mbps and 100Mbps) in the hub, which are linked by a

switch, so your 10Mbps and 100Mbps workstations and equipment can

communicate.

The hub also has two transceiver module slots that can be fitted with a

Management Module, or 3Com 10Mbps or 100Mbps modules to provide

you with additional types of network connection. For information on

what modules can be used, refer to the " Products " section in this guide.

The Dual Speed Hub 500 comes with:

One power cord for use with the Dual Speed Hub 500

Four self-adhesive rubber pads

Mounting kit

A Warranty Registration card for you to fill out and return

The Dual Speed Hub 500 is suited for office use where it can be free

standing, wall-mounted, or rack-mounted (in a wiring closet or

equipment room).

The unit can be powered either from the AC mains supply, or through

an optional 3Com SuperStack II Advanced Redundant Power System

(3C16070). Contact your supplier for details.

To provide maximum flexibility and expandability, the Dual Speed

Hub 500 can be used with a range of other equipment:

Using Cascade Cables, you can connect up to eight Dual Speed

Hub 500 units to form a logical repeater (called a stack ), providing

up to 208 ports per stack. The 10Mbps and 100Mbps segments in

each hub are connected by the Cascade Cables. Using additional

Hot Swap Cascade Units, you can add resilience to the cascade

connections so that you can remove units at any time without it

affecting communication across the other units in the stack.

Using the MDI switch on the front panel, you can connect a

10BASE-T or 100BASE-TX unit or stack to the Dual Speed Hub 500.

Using a Dual Speed Hub – PS Hub Cascade Converter Kit, you can

stack Dual Speed Hub 500 units with existing SuperStack II

PS Hubs. The whole stack can be managed as a single entity. The

maximum number of units that you can connect this way to form

a stack is eight.
