Safety Compliance

Warning: Fiber Optic Port Safety

Avertissment: Ports pour fibres optiques - sécurité sur le plan
optique

Warnhinweis: Faseroptikanschlüsse - Optische Sicherheit

Underwriters Laboratories Compliance Statement

Important!

Before making connections, make sure you have the correct cord set. Check it (read

the label on the cable) against the following:

The unit automatically matches the connected input voltage. Therefore, no additional adjustments
are necessary when connecting it to any input voltage within the range marked on the rear panel.

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.

Niemals ein Übertragungslaser betrachten, während dieses eingeschaltet
ist. Niemals direkt auf den Faser-TX-Anschluß und auf die
Faserkabelenden schauen, während diese eingeschaltet sind.

c. Das Gerät war Feuchtigkeit ausgesetzt.
d. Wenn das Gerät nicht der Bedienungsanleitung entsprechend funktioniert oder Sie mit

Hilfe dieser Anleitung keine Verbesserung erzielen.
e. Das Gerät ist gefallen und/oder das Gehäuse ist beschädigt.
f. Wenn das Gerät deutliche Anzeichen eines Defektes aufweist.

15. Zum Netzanschluß dieses Gerätes ist eine geprüfte Leitung zu verwenden. Für einen
Nennstrom bis 6A und einem Gerätegewicht größer 3 kg ist eine Leitung nicht leichter als
H05VV-F, 3G, 0.75 mm

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. This switch also features full-duplex capability on all
ports, which effectively doubles the bandwidth of each connection.

Auto-negotiation is used to select the optimal transmission speed and
communication mode for each connection. With store-and-forward
switching and flow control, maximum data integrity is always maintained,
even under heavy loading.

This switch includes two slots on the front panel for slide-in 1000BASE-T,
100BASE-FX, or 1000BASE-X (GBIC) modules. Cascade connections
between switches can be made using these modules.

The switch also supports a stacking module that can be installed into slot
M2. The stacking module allows up to eight units to be linked together and
managed from one unit using one IP address.

Management Options

This switch contains a comprehensive array of LEDs for “at-a-glance”
monitoring of network and port status. It also includes a management
agent that allows you to configure or monitor the switch using its
embedded management software, or via SNMP applications. To manage
the switch, you can make a direct connection to the RS-232 console port
(out-of-band), or you can manage the switch through a network
connection (in-band) using Telnet, the on-board Web agent, or
Windows-based network management software.

The management agent provides a wide range of advanced
performance-enhancing features. Port-based VLANs provide traffic
security and efficient use of network bandwidth. QoS priority queueing
ensures the minimum delay for moving real-time multimedia data through
the switch. Flow control eliminates the loss of packets due to bottlenecks
caused by port saturation. Port security is provided to filter unwanted
traffic from the switch.

For a detailed description of the switch’s advanced features, refer to the
Management Guide.

Description of Hardware

RJ-45 Ports

The switch base unit contains 24 10BASE-T/100BASE-TX RJ-45 ports.
All of these ports support automatic MDI/MDI-X operation, so you can
use straight-through cables for all network connections to PCs or servers,
or to other switches or hubs. (See “10BASE-T/100BASE-TX Pin
Assignments” on page B-2.)

Each of these ports support auto-negotiation, so the optimum
transmission mode (half or full duplex), and data rate (10 or 100 Mbps) can
be selected automatically, if this feature is also supported by the attached
device. If a device connected to one of these ports does not support
auto-negotiation, the correct speed will be sensed by the port, but the
transmission mode will default to half duplex.

Each port also supports auto-negotiation of flow control, so the switch
can automatically prevent port buffers from becoming saturated.

Ports Status LEDs

The base unit also includes a display panel for key system and port
indications that simplify installation and network troubleshooting. The

Figure 1-4. Single-Port 1000BASE-T Gigabit Module

Using Category 5, 5e, or 6 twisted-pair cable you can connect to another
device up to 100 m (328 ft) away. The 1000BASE-T module operates at
10/100/1000 Mbps. At 1000 Mbps it operates at full duplex and supports
auto-negotiation of speed and flow control. At 10/100 Mbps it supports
auto-negotiation of speed, duplex mode (i.e., half or full duplex), and flow
control. Note that you should first test the cable installation for IEEE

802.3ab compliance. See “1000BASE-T Cable Requirements” on page B-6.

Stack Flashing Amber An initial state of stacking configuration upon

powering on.

Flashing Green When the user enters the light unit command

in the CLI, the unit ID of each switch in the
stack will be displayed by port LEDs 1 to 8.

Using single-mode fiber optic cable, the 100BASE-FX port can be
connected to a remote site up to 20 km (12.4 miles) away. The
100BASE-FX module operates at 100 Mbps, with support for full-duplex
mode and flow control.

Using multimode fiber optic cable, the 100BASE-FX port can be
connected to a remote site up to 2 km (1.24 miles) away. The
100BASE-FX module is fixed to operate at 100 Mbps full duplex, and
supports auto-negotiation for flow control. This module is fitted with an
SC connector, but you can attach an ST plug to the switch using the SC-ST
Converter (Part Number: 99-012034-091).
