a functionally equivalent Product or part in receipt of customer’s request, provided that the customer complies with the return material authorization (RMA)
procedures and returns all defective Product prior to installation of the replacements to RubyTech.
All defective Products must be returned to RubyTech with issuance of a Return Material Authorization number (RMA number) assigned to the reseller from
whom the end customer originally purchased the Product. The reseller is responsible for ensuring the shipments are insured, with the transportation
charges prepaid and the RMA number clearly marked on the outside of the package. RubyTech will not accept collect shipments or those returned without
an RMAnumber.

1. Introduction
1-1. Overview of ES-2226C
ES-2226C, 24 Fast Ethernet + 2 Gigabit L2 Managed Switch, implemented
24 10/100Mbps TP + 2 Gigabit dual media ports with TP/SFP(or GBIC), is a
standard switch that meets all IEEE 802.3/u/x/z Gigabit, Fast Ethernet and Ethernet
specifications. The switch can be managed through RS-232 serial port via directly
connection, or through Ethernet port using Telnet or Web-based management unit,
associated with SNMP agent. With the SNMP agent, the network administrator can
logon the switch to monitor, configure and control each port’s activity in a friendly
way. The overall network management is enhanced and the network efficiency is
also improved to accommodate high bandwidth applications. In addition, the switch
features comprehensive and useful function such as DHCP Option 82, QoS (Quality
of Service), Spanning Tree, VLAN, Port Trunking, Bandwidth Control, Port Security,
SNMP/RMON and IGMP Snooping capability via the intelligent software. It is
suitable for both metro-LAN and office application.
• Model Description
Model Port 25, 26 Configurations
ES-2226C Two types of media --- TP and SFP Fiber
ES-2226C Two types of media --- TP and GBIC Fiber
10/100/1000Mbps TP is a standard Ethernet port that meets all IEEE
802.3/u/x/z Gigabit, Fast Ethernet specifications. 1000Mbps SFP Fiber transceiver
is a Gigabit Ethernet port that fully complies with all IEEE 802.3z and 1000Base-
SX/LX standards.
1000Mbps Single Fiber WDM (BiDi) transceiver is designed with an optic
Wavelength Division Multiplexing (WDM) technology that transports bi-directional
full duplex signal over a single fiber simultaneously.
For upgrading firmware, please refer to the Section 3-20 or Section 4-2-2 for
more details. The switch will not stop operating while upgrading firmware and after
that, the configuration keeps unchanged.

• Key Features in the Device
DHCP Option 82:
This feature enables the Dynamic Host Configuration Protocol (DHCP)
relay agent information (option 82) (ES-2226C switch) to include
information about itself and the attached client when forwarding DHCP
requests from a DHCP client to a DHCP server via Trust Port. The DHCP
server can use this information to assign IP addresses、gateway、subnet
mask、DNS for each subscriber of a service-provider network.
QoS:
Support Quality of Service by the IEEE 802.1P standard. There are two
priority queue and packet transmission schedule using Weighted Round
Robin (WRR). User-defined weight classification of packet priority can be
based on either VLAN tag on packets or user-defined port priority.
Spanning Tree:
Support IEEE 802.1D, IEEE 802.1w (RSTP: Rapid Spanning Tree
Protocol) standards.
VLAN:
Support Port-based VLAN and IEEE802.1Q Tag VLAN. Support 256 active
VLANs and VLAN ID 1~4094.
Port Trunking:
Support static port trunking and port trunking with IEEE 802.3ad LACP.
Bandwidth Control:
Support ingress and egress per port bandwidth control.
Port Security:
Support allowed, denied forwarding and port security with MAC address.
SNMP/RMON:
SNMP agent and RMON MIB. In the device, SNMP agent is a client
software which is operating over SNMP protocol used to receive the
command from SNMP manager (server site) and echo the corresponded
data, i.e. MIB object. Besides, SNMP agent will actively issue TRAP
information when happened.
RMON is the abbreviation of Remote Network Monitoring and is a branch of
the SNMP MIB.
The device supports MIB-2 (RFC 1213), Bridge MIB (RFC 1493), RMON
MIB (RFC 1757)-statistics Group 1,2,3,9, Ethernet-like MIB (RFC 1643) and
so on.
IGMP Snooping:
Support IGMP version 2 (RFC 2236): The function IGMP snooping is used
to establish the multicast groups to forward the multicast packet to the
member ports, and, in nature, avoid wasting the bandwidth while IP
multicast packets are running over the network.
