Overview
The KS-C48G-T-6YQ from the Carbon series is a Layer 3 managed core switch with high port density, developed for data integration in data centers. It combines 48 Gigabit Ethernet ports, 4 SFP28 uplink ports running at 25 Gbps and 2 QSFP uplink ports running at 40 Gbps, and delivers 456 Gbps of bandwidth. A non-PoE design focused on fast processing, a dual 120W power supply and an advanced cooling system make it a powerful backbone for scalable networks.

Frequently asked questions
Questions about this product
Why does operating temperature matter for network switches?
High temperatures can shorten component life and reduce the product's stability. Good ventilation and staying within the specified temperature range are important.
Do network switches need a UPS?
If a power outage would interrupt the service or cause data loss, putting sensitive equipment on a UPS can be worthwhile.
Can several network switches be used on the same network?
Yes. With a properly designed addressing scheme, network capacity, VLANs and management resources, multiple devices can be deployed within a standard architecture.
How do VLANs help with network switches?
VLANs can separate the traffic of different services and improve management, security and broadcast control. However, they must be designed correctly and configured on the equipment at both ends.
What is SNMP used for in managing network switches?
SNMP allows monitoring systems to collect management information such as interface status, resource usage and certain health indicators.
Frequently asked questions: Network Switches
Answers to common questions about this product line, from the KDT Help Center.
Where should I start when choosing the right network switches?
Start by defining the intended use, the number of devices, the installation environment, the capacity required and your plans for future expansion. Then choose the model and technical specifications based on what the project actually needs.
Which technical specifications matter most for network switches?
Depending on the project, the most important specifications are capacity, speed, compatibility, environmental ratings, management features and scalability. Basing your choice on a single figure is usually not enough.
Is a cheaper network switch model always the right choice?
No. The purchase price is only one factor. You also need to consider reliability, features, service life, after-sales service and maintenance costs.
How do I work out how much capacity a switched network needs?
Base the calculation on the number of devices, actual usage, how long the system will be in use and how much the project is likely to grow. It is also wise to keep some capacity in reserve.
Can network switches be upgraded later?
In many cases, some of the capacity or equipment can be upgraded. However, this depends on the product's architecture and its hardware limitations, so check before you buy.
