10/100-Mbps Fast Ethernet Ports
10/100/1000-Mbps Gigabit Ethernet Ports
• Autosensing (autonegotiation) of port speed and autonegotiating of duplex mode optimizes port
bandwidth.
• Automatic-medium-dependent interface crossover (auto-MDIX) capability automatically detects
the required cable connection type (straight-through or crossover) and configures the connection
appropriately.
PoE-Capable Ports (Available only on the Catalyst Express 500-24LC and Catalyst Express 500-24PC
switches.)
• Up to 15.4 W of power provided to connected Cisco prestandard and IEEE 802.3af-compliant
powered devices if the switch detects that there is no power on the circuit.
SFP Module Slots
• Fiber-optic SFP modules provide cable media and distance options for switch connectivity. A list
of supported Cisco SFP modules is in the “Supported Hardware” section on page 1-13.
LEDs
• System LEDs show switch status, problem detection, PoE usage, and setup status.
• Port LEDs show port status. From the device manager GUI, port LEDs also show duplex mode,
speed, and PoE status.
• RPS LED shows status of an installed Cisco redundant power supply (RPS). (Available only on the
Catalyst Express 500-24PC model.)
Setup Button
• Button starts the Express Setup program.
Cisco Redundant Power Supply (RPS)
• Cisco redundant power supply (RPS) enhances power reliability. A list of supported RPS models
is in the “Supported Hardware” section on page 1-13. (Available only on the Catalyst
Express 500-24PC model.)
