Power Cord Safety
Please read the following safety information carefully before
installing the switch:
WARNING: Installation and removal of the unit must be carried out by qualified personnel
only.
• The unit must be connected to an earthed (grounded) outlet to comply with international
safety standards.
• Do not connect the unit to an A.C. outlet (power supply) without an earth (ground)
connection.
• The appliance coupler (the connector to the unit and not the wall plug) must have a
configuration for mating with an EN 60320/IEC 320 appliance inlet.
• The socket outlet must be near to the unit and easily accessible. You can only remove
power from the unit by disconnecting the power cord from the outlet.
• This unit operates under SELV (Safety Extra Low Voltage) conditions according to
IEC 60950. The conditions are only maintained if the equipment to which it is connected
also operates under SELV conditions.

This unit cannot be powered from IT†supplies. If your supplies are of IT type, this unit
must be powered by 230 V (2P+T) via an isolation transformer ratio 1:1, with the
secondary connection point labelled Neutral, connected directly to earth (ground).
†Impédance à la terre
When using a fiber optic port, never look at the transmit laser while it is
powered on. Also, never look directly at the fiber TX port and fiber cable
ends when they are powered on.
Ne regardez jamais le laser tant qu'il est sous tension. Ne regardez
jamais directement le port TX (Transmission) à fibres optiques et les
embouts de câbles à fibres optiques tant qu'ils sont sous tension.

Chapter 1: Introduction
Overview
The SMC8926EM and SMC8950EM are intelligent multilayer switches (Layer 2, 3)
with 24/48 10/100/1000BASE-T ports, four of which are combination ports*that are
shared with four SFP transceiver slots (see Figure 1-1, Ports 21-24/45-48). The rear
panel provides two slots for single-port 10 Gigabit Ethernet hot-swappable
expansion modules, and two stacking ports. Units can be stacked up to eight high
through the built-in stacking ports that provide a 50 Gbps stack backplane.
The switches include an SNMP-based management agent embedded on the main
board, which supports both in-band and out-of-band access for managing the stack.
These switches can easily tame your network with full support for Spanning Tree
Protocol, Multicast Switching, Virtual LANs, and IP routing. It brings order to poorly
performing networks by segregating them into separate broadcast domains with
IEEE 802.1Q compliant VLANs, empowers multimedia applications with multicast
switching and CoS services, and eliminates conventional router bottlenecks.
These switches can be used to augment or completely replace slow legacy routers,
off-loading local IP traffic to release valuable resources for non-IP routing or WAN
access. With wire-speed performance for Layer 2 and Layer 3, these switches can
significantly improve the throughput between IP segments or VLANs.

Switch Architecture
These Gigabit Ethernet switches employ a wire-speed, non-blocking switching
fabric. This permits simultaneous wire-speed transport of multiple packets at low
latency on all ports. The switches also feature full-duplex capability on all ports,
which effectively doubles the bandwidth of each connection.
For communications between different VLANs, these switches use IP routing. For
communications within the same VLAN, they use 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.
These switches include built-in stacking ports that enable up to eight units to be
connected together through a 48 Gbps stack backplane. The switch stack can be
managed from a master unit using a single IP address.
These switches also include two slots on the rear panel for slide-in single-port
10GBASE modules with XFP transceivers.
Network Management Options
These switches contain a comprehensive array of LEDs for “at-a-glance” monitoring
of network and port status. They also include a management agent that allows you
to configure or monitor the switch using its embedded management software, or via
SNMP applications. To manage each switch, you can make a direct connection to
the console port (out-of-band), or you can manage the switches through a network
connection (in-band) using Telnet, the on-board web agent,or SNMP-based network
management software.
For a detailed description of both switches’ advanced features, refer to the Gigabit
Ethernet Switch Management Guide.
