26 Hardware DescriptionPowerConnect Back Panel Port DescriptionThe device back panel contains connectors for power, as illustrated in the Figure 2-2.Figure 2-2. Device Back PanelOn the device back panel are two power supply connectors and an RS-232 Console port. For general usethere is an AC Power Supply connector which is connectable to either 110V or 220V power supplies.The DC Power Supply connector is to connect a Redundant Power Supply (RPS) to be activatedautomatically in the event of an AC power supply outage.Device PortsSFP PortsThe Small Form Factor Plugable (SFP) port is a hot swappable optical modular transceiver that offershigh speed and compactness, which is designated as 1000Base-SX or LX.RS-232 Console PortOne DB-9 connector for a serial terminal connection which is used for debugging, software download,etc. The default baud rate is 9600 bps. The baud rate can be configured from 2400 bps up to 38400 bps.Figure 2-3. Console PortCombo PortsA combo port is a single logical port with two physical connections:• A RJ-45 connection for Twisted Pair copper cabling• A SFP connection for various fiber-based modulesOnly one of the two physical connections of a combo port may be used at any one time. Port features andavailable port controls are determined by the physical connection used.The system automatically detects the media used on a combo port, and utilizes this information in alloperations and control interfaces.
