Connectivity
• 24 100BASE-TX ports, 2 1000BASE-T ports, and 2 combination 1000BASE-T/
SFP ports for easy integration and for protection of your investment in legacy LAN
equipment.
• Auto-negotiation enables each RJ-45 port to automatically select the optimum
speed (10, 100 or 1000 Mbps), and the communication mode (half or full duplex)
if this feature is supported by the attached device; otherwise the port can be
configured manually.
• 100BASE-TX and 1000BASE-T RJ-45 ports support auto MDI/MDI-X pinout
configuration.
• 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 802.3-2002 Ethernet, Fast Ethernet, Gigabit Ethernet compliance ensures
compatibility with standards-based hubs, network cards and switches from any
