What is the maximum PoE power budget of the Cisco WS-C3750E-48PD-S switch? The Cisco WS-C3750E-48PD-S has a 750W power supply, supporting a maximum PoE budget of 740W. This allows it to deliver up to 30W per port (IEEE 802.3at PoE+) across its 48 luke, ideal for powering devices like IP phones, wireless access points, and security cameras. Ensure connected devices’ total power requirements do not exceed the 740W limit to avoid overloading the switch.

Does the WS-C3750E-48PD-S support 10 Gigabit uplinks? Da, this switch includes two built-in 10 Gigabit Ethernet (X2-based) uplink ports for high-speed backbone connectivity. The X2 slots are fixed and support 10G modules like Cisco X2-10GB-SR for fiber or X2-10GB-T for copper. Note that X2 modules are older; newer SFP+ modules are not compatible without an adapter, which may affect performance.

Is the Cisco 3750-E Series still supported with software updates? Cisco ended official software support for the 3750-E series, including this model, in 2020. Međutim, the IP Base feature set (installed by default) includes Layer 3 routing, VLANs, QoS, and basic security. Third-party vendors may offer limited firmware updates or troubleshooting, but critical security patches are no longer provided by Cisco.

Can the switch be stacked with other 3750-E models? Da, the WS-C3750E-48PD-S supports Cisco StackWise Plus technology, allowing you to stack up to nine switches with a 64Gbps stacking bandwidth. Use Cisco StackWise cables to connect units, creating a single logical switch for simplified management. Ensure all stacked switches run the same IOS version to avoid compatibility issues.

Why choose a used WS-C3750E-48PD-S over a newer model? This switch offers a cost-effective solution for businesses needing reliable PoE+ and Layer 3 features without the expense of newer hardware. Its 48 PoE+ ports and 10G uplinks are sufficient for mid-sized networks, such as offices or campuses. Međutim, verify the unit’s condition, including fan health, power supply functionality, and absence of software licensing issues, as older hardware may have shorter lifespans. Purchasing from a reputable refurbished vendor with testing and warranty is recommended.
