COMPLIANCES AND SAFETY STATEMENTS
FCC CLASS A
This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual, may
cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his own
expense.
You are cautioned that changes or modifications not expressly approved by
the party responsible for compliance could void your authority to operate
the equipment.
You may use unshielded twisted-pair (UTP) for RJ-45 connections -
Category 3 or better for 10 Mbps connections, Category 5 or better for 100
Mbps connections, Category 5, 5e, or 6 for 1000 Mbps connections. For
fiber optic connections, you may use 50/125 or 62.5/125 micron
multimode fiber or 9/125 micron single-mode fiber.
INDUSTRY CANADA - CLASS A
This digital apparatus does not exceed the Class A limits for radio noise
emissions from digital apparatus as set out in the interference-causing
equipment standard entitled “Digital Apparatus,” ICES-003 of the
Department of Communications.
Cet appareil numérique respecte les limites de bruits radioélectriques
applicables aux appareils numériques de Classe A prescrites dans la norme

1INTRODUCTION
OVERVIEW
The ES-3026 and ES-3026P are Fast Ethernet Layer 2 switches with 24 10/
100-BASE-T ports, and two Small Form Factor Pluggable (SFP) transceiver
slots that operate in combination with 1000-BASE-T ports 25~26 (see
Figure 1 on page 16, Ports 25-26). The ES-3026P also provides PoE power
to connected devices. The switches also include an SNMP-based
management agent, which provides both in-band and out-of-band access
for managing the switch.
Both switches provide a broad range of powerful features for Layer 2
switching, delivering reliability and consistent performance for your
network traffic. They bring order to poorly performing networks by
segregating them into separate broadcast domains with IEEE 802.1Q
compliant VLANs, and empowers multimedia applications with multicast
switching and CoS services.

Switch Architecture

ES-3026/3026P
SWITCH ARCHITECTURE
The switch employs a wire-speed, non-blocking switching fabric. This
permits simultaneous wire-speed transport of multiple packets at low
latency on all ports. The switch also features full-duplex capability on all
ports, which effectively doubles the bandwidth of each connection.
This switch uses store-and-forward switching to ensure maximum data
integrity. With store-and-forward switching, the entire packet must be
received into a buffer and checked for validity before being forwarded. This
prevents errors from being propagated throughout the network.
NETWORK MANAGEMENT OPTIONS
With a comprehensive array of LEDs, the switch provides “at a glance”
monitoring of network and port status. The switch can be managed over
the network with a web browser or Telnet application, or via a direct
connection to the console port. The switch includes a built-in network
management agent that allows it to be managed in-band using SNMP or
RMON (Groups 1, 2, 3, 9) protocols. It also has an RJ-45 serial port (DB-9
connector) for out-of-band management. A PC may be connected to this
port for configuration and monitoring out-of-band via the supplied RJ-45 to
RS232 (DB-9 connector) serial cable.
For a detailed description of the management features, refer to the User
Manual.
POWER-OVER-ETHERNET
The first six ports (ports 1~6) of the ES-3026P's 24 10/100 Mbps ports
support the IEEE802.3at Draft standard version that enables DC power to
be supplied to attached devices using wires in the connecting Ethernet
cable. The rest of the ES-3026P's 24 10/100 Mbps ports (ports 7~24)
support the normal PoE (802.3af). The total PoE power delivered by all
ports cannot exceed 185W power budget.
Any PoE-compliant device attached to a port can directly draw power from
the switch over the Ethernet cable without requiring its own separate
power source. This capability gives network administrators centralized
power control for devices such as IP phones and wireless access points,
which translates into greater network availability.
For each attached PoE-compliant device, the switch automatically senses
the load and dynamically supplies the required power. The switch delivers
power to a device using the wire pairs in UTP or STP cable. The first six
ports on the switch can provide up to 30 W of power, while the remaining
ports (ports 7~24) can provide 15.4W of power.

Description of Hardware

ES-3026/3026P
DESCRIPTION OF HARDWARE
10/100BASE-T
PORTS
The switch contains 24 RJ-45 ports that operate at 10 Mbps, or 100 Mbps,
half or full duplex. Because these ports support automatic MDI/MDI-X
operation, you can use straight-through cables for all network connections
to PCs or servers, or to other switches or hubs.
Each of these ports supports auto-negotiation, so the optimum
transmission mode (half or full duplex), and data rate (10, or 100 Mbps)
can be selected automatically. If a device connected to one of these ports
does not support auto-negotiation, the communication mode of that port
can be configured manually.
Each port also supports IEEE 802.3x auto-negotiation of flow control, so
the switch can automatically prevent port buffers from becoming
saturated.
SFP TRANSCEIVER
SLOTS
The Small Form Factor Pluggable (SFP) transceiver slots are shared with
Gigabit RJ-45 ports 25~26. In the default configuration, if an SFP
transceiver (purchased separately) is installed in a slot and has a valid link
on the port, the associated RJ-45 port is disabled. The switch can also be
configured to force the use of an RJ-45 port or SFP slot, as required.
The following table shows a list of transceiver types which have been
tested with the switch. For an updated list of vendors supplying these
transceivers, contact your local dealer. For information on the
recommended standards for fiber optic cabling, see “Fiber Standards” on
page 50.
