Optional Redundant Power Unit
The switch 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 the 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 10/100/1000 Mbps 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 ports support auto MDI/MDI-X pinout selection.
