CHAPTER 1
Getting to Know Your Switch
1.1 Introduction
The Switch refers to all the following models unless a particular model is specified.
• XMG-105HP
• XMG-108
• XMG-108HP
The Switch is a 100 Mbps / 1/2.5/10 Gbps multi-port switch that can be used to build high-performance
switched workgroup networks. The Switch is a store-and-forward device that offers low latency for high-
speed networking. The Switch is designed for workgroups, departments or backbone computing
environments for small businesses.
All models are referred to as the “Switch” in this guide.
The following table describes the hardware features of the Switch by model.
The PoE ports can supply power to the connected PoE powered devices (PDs).
The SFP+ slot is for uplink connections. Use SFP+ transceivers in these slots for 1 Gbps or 10 Gbps
connections to backbone Ethernet switches.
The Switch has built-in loop detection. All connected port’s LED will fast blink green/yellow when it
detects that packets sent out on that port loop back to the Switch.
The Switch has built-in IEEE 802.1p CoS (Class of Service) feature that services queues based on priority
only. As traffic comes into the Switch, traffic on the highest priority queue is transmitted first. When that
queue empties, traffic on the next highest-priority queue is transmitted until it empties, and then traffic is
transmitted on the next queue and so on. If higher priority queues never empty, then traffic on lower
priority queues never gets sent.
