Caution: To ensure proper ventilation and prevent overheating, leave a minimum clearance space
of 5.1 cm (2.0 in.) at the left and right of the switch.
Do not connect the switch to the AC power source until instructed to do so later in the installation
process.
Precaución: Para asegurar una buena ventilación y evitar que el sistema se sobrecaliente, deje un
espacio mínimo de 5.1 cm (2 pulgadas) con respecto a los lados y a la parte posterior del aparato.
No conecte el dipositivo a la fuente primaria hasta que no se le indique

Guidelines for Rackmount Installation
The installation site must be within reach of the network cabling and meet the requirements listed
below:
• Appropriate grounded power receptacles must be located within 152 cm (5 ft) of the location.
• A temperature of between 0°C (32°F) and 50°C (122°F) must be maintained at the installation
site with fluctuations of less than 10°C (18°F) per hour.
Attaching the Brackets and Installing in a Rack
The following section explains how to attach brackets to a 24 and 48 port switch and then how to
install this switch in a rack. There are eight 24 and 48 port switches that can be installed following
this procedure. They are the 08H20G4-24, 08H20G4-24P, 08H20G4-48, 08H20G4-48P, 08G20G4-24,
08G20G4-24P, 08G20G4-48, and 08G20G4-48P. Proceed as follows to install the switch into a
19-inch rack:
1. Attach the rackmount brackets to the switch, as shown in Figure 2-2, using the eight M3x6
mm flathead screws shipped with the switch.
Figure 2-2 Attaching the Rackmount Brackets
2. With the mounting brackets attached, position the switch between the vertical frame members
of the 19-inch rack as shown in Figure 2-3. Then fasten the switch securely to the frame using
four customer-supplied mounting screws.
Note: To ensure proper ventilation and prevent overheating, leave a minimum clearance space of
5.1 cm (2.0 in.) at the left and right of the switch.
Warning: Before rack-mounting the switch, ensure that the rack can support it without
compromising stability. Otherwise, personal injury and/or equipment damage may result.
Advertencia: Antes de montar el equipo en el rack, asegurarse que el rack puede soportar su peso
sin comprometer su propia estabilidad, de otra forma, daño personal o del equipo puede ocurrir.
Warnhinweis: Überzeugen Sie sich vor dem Einbau des Gerätes in das Rack von dessen
Stabilität, ansonsten könnten Personenschäden oder Schäden am Gerät die Folge sein.
Note: Do not install the rubber feet if you are rack mounting the switch.

Mounting the 8 Port Switches
The following mounting options are available for the 8 port switch. Each requires that you
purchase a separate mounting kit. Proceed to mount the switch in your desired location using one
of the procedures described in this section:
Install the switch in a table mount kit and mount the switch under a table, as described in
“Installing the Switch Under a Table” on page 2-10.
Install the switch in a wall mount kit and mount the switch on a wall, as described in “Installing
the Switch on a Wall” on page 2-12.
Install the switch in a lockbox kit and mount the switch on a wall, as described in “Installing the
Switch in the Lockbox and Mounting on a Wall.” on page 2-14.
