Optional Redundant Power Unit

SMC supports an optional Redundant Power Unit (RPU), that can supply power to the switch in the event of failure of the internal power supply.

Power Supply Receptacles

There are two power receptacles on the rear panel of each switch. The standard 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 or 48 dual-speed ports for easy Gigabit 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.

•RJ-45 10/100/1000BASE-T ports with auto MDI/MDI-X pinout selection.

•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, 6 or better for 1000 Mbps connections.
