Features and Benefits

Connectivity

48 (MIL-SM4804G) 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 vendor.

Provides stacking capability via RJ-45 ports with 4 Gbps stacking bandwidth. You can connect up to four MIL-SM4804G units in a stack.

Expandability

2 Small Form Factor Pluggable (SFP) transceiver slots (shared with 1000BASE-T ports)

Supports 1000BASE-SX, 1000BASE-LX, and 1000BASE-LH SFP transceivers.
