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 page1-13.
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.)
Security Slots
•Slots to attach a security cable to the switch.
