The AT-FH812u (shown in Figure 1) and AT-FH824u are manageable and
stackable Ethernet hubs with 12 or 24 dual-speed (RJ-45) ports. One slot is used
for an Optional Agent Module, and another slot for an Optional Switch Module.
The 12 and 24 port AT-FH812u-SW and AT-FH824u-SW are base unit with
optional switch modules installed. The AT-FH800-SW models are available in
North America only.
These dual-speed hubs provide the easiest method to upgrade your network to fast
Ethernet. It is not necessary to replace your existing network infrastructure. Just
add an Allied Telesyn dual-speed hub to your network and attach any 10 or 100
Mbps device to any port on the hubs. These hubs provide both the standard 10
Mbps bandwidth needed for common file transfers, and a larger channel with 100
Mbps of bandwidth that is essential for relieving serious network congestion,
running multimedia applications, or satisfying power users.
