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.

1.2 Features
The following are the essential features of the Switch.
• Conforms to IEEE 802.3u, 802.3ab, 802.3bz, 802.3z, 802.3ae, and 802.3x standards.
• Auto-negotiating 100 Mbps / 1 Gbps / 2.5 Gbps multi-gigabit Ethernet RJ-45 ports.
• Auto-sensing crossover for all 100 Mbps / 1 Gbps / 2.5 Gbps multi-gigabit Ethernet RJ-45 ports.
• Supports N-Way protocol for speed (100 Mbps / 1 Gbps / 2.5 Gbps) and duplex mode (Full) auto-
detection.
• Supports store-and-forward switching.
• Supports automatic address learning.
• Supports IEEE 802.3af, IEEE 802.3at, and IEEE 802.3bt PoE standards.
• Full wire speed forwarding rate.
• Supports 802.1p CoS.
• Embedded 4K MAC address table providing 4000 MAC addresses entries.
1.2.1 Multi-Gigabit
An 2.5 multi-gigabit port supports speeds of 2.5G if the connected device supports 2.5G and a Cat 5e
(up to 100 m) is used. The speed drops to 1G if these criteria are not met; it drops to 100M if a Cat 5
cable is used (up to 100 m).
Multi-Gigabit ports are also backward compatible with 100 Mbps and 1 Gigabit ports.
Figure 1 Multi-Gigabit Application
See the following table for the cables required and distance limitation to attain the corresponding
speed.

1.2.2 PoE
The Switch is a Power Sourcing Equipment (PSE) because it provides a source of power through its
Ethernet ports. Each device that receives power through an Ethernet port is a Powered Device (PD).
The Switch can adjust the power supplied to each PD according to the PoE standard the PD supports.
PoE standards are:
• IEEE 802.3af Power over Ethernet (PoE)
• IEEE 802.3at Power over Ethernet (PoE) +
• IEEE 802.3bt Power over Ethernet (PoE) ++
The following table describes the PoE features of the Switch by model.
1.3 Example Applications
This section shows a few examples of using the Switch in various network environments. Note that the
Switch in the figure is just an example Switch and not your actual Switch.

1.3.1 PoE Example Application
The following example figure shows a Switch supplying PoE (Power over Ethernet) to Powered Devices
(PDs) such as an IP camera, a wireless router, an IP telephone and a general outdoor router that are not
within reach of a power outlet.
Figure 2 Powered Device Example
1.3.2 Backbone Example Application
The Switch is an ideal solution for small networks where rapid growth can be expected in the near future.
The Switch can be used standalone for a group of heavy traffic users. You can connect computers and
servers directly to the Switch’s port or connect other switches to the Switch.
In this example, all computers can share high-speed applications on the server. To expand the network,
simply add more networking devices such as switches, routers, computers, print servers, and so on.
Figure 3 Backbone Application
1.3.3 Bridging or Fiber Optic Uplink Example Application
In this example, the Switch connects different company departments (RD and Sales) to the corporate
backbone. It can alleviate bandwidth contention and eliminate server and network bottlenecks. All
