power receptacle is for the AC power cord. The receptacle labeled “RPU” is for the optional Redundant Power Unit (RPU).

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, and 802.3z and 802.3ab Gigabit Ethernet compliance ensures compatibility with standards-based hubs, network cards and switches from any vendor.

Provides stacking capability via RJ-45 ports with 1 Gbps stacking bandwidth. Up to 8 units can be stacked together.

Expandability

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

Performance

Transparent bridging

Aggregate duplex bandwidth of up to 8.8 Gbps
