Introduction
Product Overview
The RocketLinx ES8108/ES8108F is an 8-port Fast Ethernet switch that is equipped with a 2.0 Gbps Packet Switch engine
designed to optimize packet forwarding and filtering to fulfill the needs of industrial communications applications. It provides
packet forwarding ability to handle 64 to 1552 packet sizes in 2 priority queues that complies with Quality of Service (QOS)
for the best data forwarding performance.
In addition, for the best network performance both broadcast storm filtering and flow control functions ensure data delivery
without traffic congestion. To avoid interference as well as to extend your network coverage, RocketLinx ES8108F provides
two models, which features two 100Mbps fiber ports with either Multi-Mode 2KM or Single-Mode 30KM transceivers to
achieve stable long distance transmissions.
To perform in hazardous environments, the ES8108/ES8108F switches are equipped with two redundant power inputs, as well
as a wide input voltage range to minimize power interruption. The switches also support a wide temperature operating range of
-25°C through 70°C. For easy maintenance, ES8108/ES8108F has one alarm relay for the port link event and the power event
to provide an alarm useful for service engineers. With their combination of industrial features, the RocketLinx ES8108/
ES8108F switches deliver superior, reliable performance even in the most demanding environments.
RocketLinx ES8108/ES8108F requires no user setup and immediately starts operating as soon as you power it up.

Introduction
Front Panel
The RocketLinx ES8108/ES8108F front panels are illustrated below.
Bottom View
The bottom view of the RocketLinx ES8108/ES8108Fconsists of one 6-pin removable terminal block connector for two DC
power inputs and an event alarm output. There is one 9-pin DIP switch on the bottom for alarm control of port or power event
selection.

Introduction
LED Indicators
There are system diagnostic LEDs and Ethernet Port LEDs located on the front panel of the RocketLinx ES8108/ES8108F.
The LED indicators provide administrators with real-time system status. The following table describes the function of each
LED indicator Refer to the figure in Front Panel on Page 7 for LED locations.
Packet Forwarding Ability
The RocketLinx ES8108/ES8108F features a packet filtering function for broadcast packet control protection and Quality of
Service (QoS). Both features can provide higher performance in a crowded network through traffic filtering and prioritization.
This subsection will introduce the principles of traffic control and forwarding precedence, including Broadcast control and
Quality of Service.
Broadcast Control
The RocketLinx ES8108/ES8108F begins to drop broadcast packets with DA (destination address) equal to
FF:FF:FF:FF:FF:FF if the received broadcast packets are more than the threshold – 198 packets/ per second at 100Mbps or 19
packets / per second at 10Mbps link speed.
All ports are enabled with this function by default to provide better network performance and prevent congestion caused by the
flooding of broadcast packets.
Quality of Service
The RocketLinx ES8108/ES8108F supports the frame type priority function, where high priority packets will be queued to a
high priority queue to share more bandwidth. The ratio of bandwidth of the high priority to the low priority queue is 8:1. After
8 high priority packets are processed, then 1 low priority packet is processed.
Both the RocketLinx ES8108 and RocketLinx ES8108F can examine the specific bits of VLAN Tag and TCP/IP TOS of IPv4
and IPv6.

IEEE 802.1Q tag based CoS RocketLinx ES8108/ES8108F User Guide: 2000514 Rev. B - 9
Introduction
IEEE 802.1Q tag based CoS
The RocketLinx ES8108/ES8108F checks the 3 bits of the priority field carried by a VLAN tag and maps it to the
corresponding priority. A packet with a priority field ranging from 0 to 3 will be treated as a low priority packet, and will be
stored in a low priority queue. A packet with a priority field ranging from 4 to 7 will be treated as a high priority packet, and
will be stored in the high priority queue.
IEEE 802.1Q Type of Service for IPv4 /IPv6 packet
The RocketLinx ES8108/ES8108F also provides the IP layer CoS (Class of Service) function by recognizing the priority octet
and mapping it to the corresponding priority. For an IPv4 packet, it is embedded in the TOS (Type of Service) Octet.
IPv4 Frame Format

10 - RocketLinx ES8108/ES8108F User Guide: 2000514 Rev. B IEEE 802.1Q Type of Service for IPv4 /IPv6 packet
Introduction
For an IPv6 data packet, the Traffic Class Octet is used to differentiate the Class of Service. When this function is enabled, the
RocketLinx ES8108/ES8108F will automatically recognize the IP version and capture either the TOS field (IPv4) or Traffic
Class field (IPv6) and distribute the packet into the High or Low Queue.
