The SuperStack II Switch 1000BASE-T Module provides a
Gigabit Ethernet module for the SuperStack II Switch
1100 (12 and 24 port), SuperStack II Switch 3300 (12

The module requires management software version 2.42
or later to be installed on the Switch. For instructions on
upgrading management software, refer to the
documentation supplied with your Switch.
The module conforms to the full duplex implementation
of the Gigabit Ethernet standard IEEE 802.3ab. The

Category 5 copper cabling and RJ-45 connectors, as
defined in the ANSI/TIA/EIA-568-A Commercial Building
Telecommunications Cabling Standard, and in the
1000BASE-T standard.
A white paper which describes 1000BASE-T technology
and cabling requirements in more detail is available from
