The module provides two 1 Gbps ports via USB Type-A connectors. The right port is
for transmit and the left port for receive. The module allows up to eight switches to
be linked together using stacking cables. The push button on the module enables
one switch in the stack to be selected as the master.
Features and Benefits
Connectivity
• 24 dual-speed ports for easy Fast Ethernet integration and for protection of your
investment in legacy LAN equipment.
• Auto-negotiation enables each RJ-45 port to automatically select the optimum
communication mode (half or full duplex) if this feature is supported by the
attached device; otherwise the port can be configured manually.
• Independent RJ-45 10/100BASE-TX ports with auto MDI/MDI-X.
• Unshielded (UTP) cable supported on all RJ-45 ports: Category 3 or better for
10 Mbps connections, Category 5 or better for 100 Mbps connections, and
Category 5, 5e or 6 for 1000 Mbps connections.
• IEEE 802.3 Ethernet, 802.3u Fast Ethernet, 802.3z and 802.3ab Gigabit Ethernet
compliance ensures compatibility with standards-based hubs, network cards and
switches from any vendor.
