❓ Frequently Asked Questions
Q1: Is this 3Com 5500G-EI switch compatible with current network equipment?
Yes, this Gigabit Ethernet switch is fully compatible with all standard network equipment complying with IEEE 802.3 standards. It works perfectly with switches, routers, and servers from all brands (Cisco, HP, Dell, Netgear, etc.). The 48 ports automatically negotiate speeds of 10/100/1000 Mbps for maximum compatibility.
Q2: What is the difference between the RJ-45 ports and the SFP ports on this manageable switch?
The 48 RJ-45 10/100/1000Base-T ports use standard copper Ethernet cables (Cat5e/Cat6) with a maximum range of 100 meters. The 4 SFP (Small Form-factor Pluggable) ports accept optical modules for fiber optic connections, allowing much longer distances (up to several kilometers depending on the module). On this 3Com SuperStack model, 4 ports are dual-purpose, allowing the use of either the RJ-45 port or the corresponding SFP port.
Q3: Can the 3Com 5500G-EI Layer 3 switch be stacked with other units?
Absolutely! This switch features 2 XRN (eXpandable Resilient Networking) ports allowing you to create a stack of up to 8 5500G-EI switches, managed as a single entity with one IP address. XRN technology offers a stacking bandwidth of 48 Gbps full-duplex per port, enabling high-performance interconnection between stacked units for a total of up to 448 Gigabit ports.
Q4: Does this 3Com network switch support VLANs and inter-VLAN routing?
Yes, as a Layer 3 switch, the 3Com 5500G-EI fully supports VLANs (Virtual Local Area Networks) as well as native inter-VLAN routing. You can create and manage multiple VLANs to segment your network, and the switch will route between these VLANs without needing an external router. It also supports advanced protocols like spanning tree, link aggregation, and QoS management to optimize enterprise network performance.
Q5: What warranty and support are offered with this used Gigabit switch?
We offer a 30-day warranty covering any hardware defects. The switch has been thoroughly tested before shipment to ensure proper operation. Each order includes a professional invoice with 0% VAT and secure shipping with tracking number. However, we do not provide technical support, software configuration, or installation assistance. The equipment is sold for use by qualified IT professionals capable of configuring and managing professional network switches.
Q6: Can I use this 3Com switch for a PoE (Power over Ethernet) network?
This specific model (3CR17255-91) is the standard version without built-in PoE. For Power over Ethernet IEEE 802.3af support, you would need the 3CR17253-91 (PWR version) equipped with a PoE-compatible power supply. However, this switch delivers excellent performance for all standard network equipment and remains a reliable professional solution for enterprise infrastructures that do not require PoE.
Q7: Is the switch noisy and what is its actual power consumption?
The 3Com SuperStack 4 5500G-EI 48-Port generates a noise level of about 53 decibels, comparable to a normal conversation, which is standard for an enterprise switch with active cooling. The maximum power consumption is 142W, but under normal use with moderate load, it typically ranges between 80-100W. The switch features an energy-efficient design and excellent reliability with an MTBF of 25 years, ensuring durable and economical operation.
