WS-CE520-24LC-K9 combines 24 Fast Ethernet access ports with PoE on four ports and two fixed Gigabit combo uplinks. This managed Layer 2 switch belongs to the Catalyst Express 520 family and uses a full-width, single-rack-unit chassis. Each uplink supports either its copper connection or its SFP connection, rather than both simultaneously. The configuration connects ordinary desktop equipment alongside a limited number of powered IP phones, wireless access points, or cameras. The discontinued WS-CE520-24PC-K9 differs by supplying PoE across all 24 access ports. Cisco Catalyst Express 520-24LC retains the mixed powered and unpowered access configuration, so an installed-base purchase should match the endpoint connections rather than treating every access port as a power source.

8.8 Gbps switching capacity provides the forwarding bandwidth for the access connections and uplinks. 6.6 Mpps forwarding handles packet processing separately from that bandwidth rating. An 8000-entry MAC address table supports Layer 2 address learning; the platform does not provide IP routing. WS-CE520-24LC-K9 carries 64 MB of DRAM for its operating software, while Cisco IOS provides the underlying operating system. 110W maximum power consumption is the figure to use when allocating electrical capacity, not a statement of power available to attached endpoints. Cisco Configuration Assistant supplies graphical configuration for the managed switch. Hardware stacking is absent, so connecting additional chassis does not create a shared stack forwarding system. The Catalyst Express configuration therefore remains a standalone switching device rather than an expandable stack member.
ORM Systems offers WS-CE520-24LC-K9 new sealed or certified refurbished, with ORM warranty coverage of up to 3-year extended for new units and up to 1 year for certified refurbished units; Cisco's original Limited Lifetime Hardware Warranty ended with support on December 17, 2014. Certified refurbished units are inspected and bench-tested, including power-on and POST, rated-speed links on every port, clean boot, and PoE output verified under load on every powered port. Specify condition and quantity on the purchase order; returns are 30 days on every condition, terms apply. Enterprise and volume orders support PO acceptance, Net-30 for government, RMA with advance replacement, and regional stock/RMA across UK, EU, US, and MEA.

When a purchase adds IP phones or access points to an existing network, match each endpoint's requirement to 15.4W PoE rather than assuming support for a newer power class. Separate powered devices from ordinary data connections in the installation schedule, and confirm endpoint compatibility before finalizing purchase quantities.
When several existing locations need consistent access controls, the three preconfigured security levels provide a common configuration starting point. Define which level each location requires before staging, rather than leaving the decision to installation personnel. Include the intended security settings and configuration responsibilities in the purchase and deployment requirements.
Gigabit connectivity at every desktop
Access connections are limited to 10/100 Mbps. Gigabit capability is confined to the uplinks, so this model cannot provide 1G connectivity to desktop endpoints.
More than four powered endpoints
Only four access ports supply PoE. A requirement to power additional endpoints directly from this chassis exceeds its powered-port count, regardless of the remaining unpowered connections.
Routing between local IP networks
Layer 2 switching does not provide IP routing between networks. The purchase must include a separate routing device when traffic needs to cross IP subnet boundaries.

WS-CE520-24LC-K9 identifies the Catalyst Express 520 configuration with 24 Fast Ethernet access ports, four supporting PoE, and two Gigabit copper-or-SFP uplinks. CE520 identifies the family, while 24LC selects this mixed powered-port configuration. Preserve the complete WS- prefix and -K9 suffix when matching a purchase order to the hardware.
WS-CE520-24LC-K9 is managed through the graphical Cisco Configuration Assistant application. Configuration includes the security slider's three preconfigured levels and Cisco Smartports settings for connected devices. Treat this as managed equipment when planning staging, and assign responsibility for applying the required configuration before the switch enters service.
WS-CE520-24LC-K9 provides four PoE access ports supporting 15.4W devices. The other 20 Fast Ethernet access ports provide data connectivity without PoE output. Match each powered endpoint to a powered connection and verify its required power class; the presence of additional data ports does not increase the powered-device count.
WS-CE520-24LC-K9 provides two fixed Gigabit combo uplinks, each offering a 10/100/1000 copper connection or a 1G SFP connection. Only one connection within each pair operates at a time. The copper and fiber connectors therefore represent two uplinks, not four independently usable connections.
No, Catalyst Express 520 switches do not form a hardware stack. WS-CE520-24LC-K9 operates as a standalone chassis, and ordinary uplink connections between switches do not create shared stack forwarding. Plan additional units as separate switches rather than ordering stacking cables or expecting a single stacked switching system.
No, WS-CE520-24LC-K9 is a Layer 2 switch without IP routing capability. A separate routing device must handle traffic between IP subnets. Keep that requirement distinct from Ethernet switching when preparing the equipment list, because connecting networks to different switch ports does not supply their routing function.
WS-CE520-24LC-K9 is retired: Catalyst Express 520 reached end of sale on December 17, 2009, and Cisco support ended on December 17, 2014. Cisco service has ended for this family. An order for this model is therefore a discontinued-hardware purchase rather than a currently supported Cisco deployment.
ORM Systems offers WS-CE520-24LC-K9 new sealed or certified refurbished. ORM's new warranty is up to 3-year extended; certified refurbished coverage is up to 1 year. Returns are 30 days on every condition, terms apply. Cisco's original Limited Lifetime Hardware Warranty ended with Cisco support on December 17, 2014.
Yes, WS-CE520-24LC-K9 is a full-width Rack-Mount 1U switch measuring 43.9 mm high, 444.5 mm wide, and 251.5 mm deep. Its weight is 3.7 kg. Use those chassis measurements when checking rack space and installation access rather than treating this model as a compact desktop switch.
WS-CE520-24LC-K9 supplies PoE on four access ports, while WS-CE520-24PC-K9 supplies PoE on all 24 access ports. Both models are discontinued. For installed-base matching, the LC configuration addresses a limited powered-device count; the PC configuration corresponds to networks requiring power across the complete access-port group.
WS-CE520-24LC-K9 provides 24 Fast Ethernet access ports, compared with eight on WS-CE520-8PC-K9. Both models are discontinued. The larger access-port count distinguishes the LC configuration for existing networks with more wired connections; the eight-port model corresponds to installations built around a smaller access-port requirement.
WS-CE520-24LC-K9 has 10/100 access ports, whereas WS-CE520G-24TC-K9 has 10/100/1000 access ports. Both models are discontinued. Existing Fast Ethernet installations correspond to the LC model's access speed; the G model corresponds to an installed-base requirement for Gigabit connections at the access ports.
WS-CE520-24LC-K9 has a published maximum power consumption of 110W. Use that maximum when allocating electrical capacity for the chassis. The figure describes switch power consumption, not a PoE output budget, so it must not be treated as power available for distribution to connected devices.
