❓ Frequently Asked Questions
✅ Has this Cisco WS-C3750X-48P-L switch been tested?
Yes, absolutely! This Cisco Catalyst WS-C3750X-48P-L switch has been fully tested in our workshops before sale. We have checked all 48 Gigabit Ethernet ports, PoE+ functions on each port, the 750W power supply, the C3KX-NM-1G network module, the StackWise Plus stacking ports, the management console, and the booting of the Cisco IOS system. The switch is fully operational and ready to be deployed in your enterprise network infrastructure.
📦 What is included with this Cisco Catalyst switch?
This Cisco WS-C3750X-48P-L switch comes fully equipped and ready to use with: the 48-port switch itself, the C3KX-NM-1G network module already installed, the 750W power supply mounted in the chassis, and a power cord. The following items are not included: RJ45 Ethernet cables, rack mounting rails, console cables, StackWise stacking cables, advanced Cisco licenses (IP Services, etc.), and Cisco SmartNet support contract.
⚡ What is PoE+ and what is the total budget available?
PoE+ (Power over Ethernet Plus) is a technology that allows powering network equipment via standard Ethernet cables, eliminating the need for separate power supplies. This WS-C3750X-48P-L switch supports the IEEE 802.3at PoE+ standard on all its 48 ports, delivering up to 30W per port. With the installed 750W power supply, the total PoE budget allows for simultaneous powering of many Cisco IP phones, Wi-Fi access points, IP surveillance cameras, and other PoE+ equipment.
📡 What is the purpose of the C3KX-NM-1G module included with the switch?
The C3KX-NM-1G module (Network Module 1 Gigabit) is a network expansion module that fits into the dedicated slot of the Catalyst 3750X switch. It allows for the addition of extra network connectivity ports (typically Gigabit SFP ports for fiber optics) beyond the 48 standard RJ45 ports, thus providing more flexibility for your uplink connections to the core network, inter-building links via fiber, or high-performance server connections.
🔗 What is StackWise Plus technology and how to use it?
StackWise Plus is Cisco's proprietary technology that allows stacking up to 9 Catalyst 3750-X switches to create a single logical switch with a stacking bandwidth of 64 Gbit/s (or 480 Gbit/s total for 9 units). The stacked switches are managed as a single entity with a unique management IP, simplifying administration. To create a stack, connect the StackWise ports between switches with special Cisco stack cables (not included, sold separately).
🌐 What network features are available with Cisco IOS LAN Base?
The included Cisco IOS LAN Base offers comprehensive features for enterprise networks: full Layer 2 switching, 255 active VLANs, static inter-VLAN routing, Spanning Tree (RSTP, PVST+, MST), Link Aggregation (LACP, PAgP), advanced QoS, 512 ACLs, DHCP snooping, Dynamic ARP Inspection, IP Source Guard, Port Security, Storm Control, IGMP/MLD Snooping, SNMP v1/v2c/v3, SSH/SSL, RADIUS, TACACS+, 802.1X. For dynamic routing (OSPF, EIGRP, BGP), an IP Services license would be required.
🔧 How to configure this Cisco Catalyst switch?
The configuration of the Cisco Catalyst WS-C3750X-48P-L can be done via several methods: CLI console (Command Line Interface) via RJ45 console port or mini-USB with terminal (PuTTY, SecureCRT), HTTPS web interface for basic graphical configuration, or SNMP/TFTP management protocols for automated deployment. Knowledge of Cisco IOS commands is strongly recommended. Note: we do not provide any technical support for configuration. Please refer to the official Cisco documentation or consult a certified Cisco network administrator.
💼 What types of environments is this switch suitable for?
The Cisco Catalyst WS-C3750X-48P-L is ideal for: SME and large enterprise networks requiring Gigabit connectivity and PoE+, university campuses with stacking and centralized management needs, environments with many Cisco IP phones and Wi-Fi access points, VoIP infrastructures requiring QoS and traffic prioritization, datacenters and server rooms for access aggregation, smart buildings with IP cameras and access control, and any environment requiring reliability, security, and enterprise-grade performance.
