7.5 8260 Ethernet 20/40-Port 10Base-T Module

The 8260 Ethernet 20-Port 10Base-T Module, a single-slot 20-port, and the 8260 Ethernet 40-Port 10Base-T Module, a two-slot 40-port are IEEE 802.3 repeater modules that comply with the 10Base-T standard and support backbone and

to-the-desk connectivity over Unshielded Twisted Pair (UTP) as well as Shielded Twisted Pair (STP) cabling. These modules provide 20 or 40 shielded RJ-45 connectors for attaching 10Base-T compliant devices using STP and/or UTP cabling for distances of up to 100 m.

Note

You can mix UTP and STP cabling on a single 20/40-port 10Base-T module.

On the 20/40-port 10Base-T modules, all the ports are internally crossed-over which allows you to connect them directly to 10Base-T transceivers without using external crossover adapters.

These modules can also be used to provide UTP/STP backbone connections between the 8260 and other 10Base-T compliant hubs such as another 8260, 8250 or 8224. In this case, an external cross-over adapter is required. As the STP cabling is not part of the 10Base-T specification, when using STP cabling, you must ensure that the hub at the other end is also capable of supporting STP cabling.

The 24/40-port 10Base-T modules provide the following features:

∙Per-port switching

Each port can be connected to one of the eight segments on the backplane. Also, the module provides eight isolated segments to which the individual ports on the module can be attached. These isolated segments can be used to set up segments consisting of the users attached to that module without using any backplane resource.

Note

The 20/40-port 10Base-T modules support up to 8 segments simultaneously. This means that the ports on these modules can be connected to a maximum of 8 segments which can be a combination of backplane and isolated segments.

∙Support for 2 E-MACs

These modules provide the mounting for two E-MACs. An E-MAC can be assigned to any of the Ethernet segments on the backplane, or any of the isolated segments on the module. Note that the E-MAC mounted on these modules cannot collect per-port or per-module statistics about the 8250 modules.

∙Support for 1 Ethernet security card

In addition to mounting for two E-MACs, these modules provide the mounting for one Ethernet security card. The Ethernet security card provides for eavesdropping and intrusion control for your Ethernet segments. For information about Ethernet security card, please refer to 7.11, ª8260 Ethernet Security Daughter Cardº on page 121.
