Cable, Port, and Pinout Information

This section describes the devices physical interfaces and provides information about cable connections. Stations are connected to the device ports through the physical interface ports on the front panel. For each station, the appropriate mode (Half/Full Duplex, Auto Negotiation) is set. The default is Auto Negotiation.

Pin Connections for the 10/100/1000 Ethernet Interface

The switching port can connect to stations wired in standard RJ-45 Ethernet station mode using straight cables. Transmission devices connected to each other use crossed cables. The following figure illustrates the pin alloca­tion.

Mounting Device

Preparing for Installation

Section 2. Mounting Device

This section contains information for installing the device, and includes the following sections:
• Preparing for Installation
• Installing the Device
• Connecting the Device
• Rack Installation
Preparing for Installation
This section provides an explanation for preparing the installation site, and includes the following topics:
• Installation Precautions
• Site Requirements
• Unpacking

Installation Precautions

Warnings
• The surface on which the switch is placed should be adequately secured to prevent it from becoming unstable and/or falling over.
• Ensure the power source circuits are properly grounded.
• Observe and follow service markings. Do not service any product except as explained in your system documentation. Opening or removing covers marked with a triangular symbol with a lighting bolt may cause electrical shock. These components are to be serviced by trained service technicians only.
• Ensure the power cable, extension cable, and/or plug is not damaged.
• Ensure the product is not exposed to water.
• Ensure the device is not exposed to radiators and/or heat sources.
• Do not push foreign objects into the device, as it may cause a fire or electric shock.
• Use the device only with approved equipment.
• Allow the product to cool before removing covers or touching internal equipment.
• Ensure the switch does not overload the power circuits, wiring, and over-current protection. To deter­mine the possibility of overloading the supply circuits, add together the ampere ratings of all devices installed on the same circuit as the device being installed. Compare this total with the rating limit for the circuit. The maximum ampere ratings are usually printed on the switch, near their AC power con­nectors.
Cautions
• Ensure the air flow around the front, sides, and back of the switch is not restricted.
• Ensure the cooling vents are not blocked.
• Do not install the switch in an environment where the operating ambient temperature might exceed 40ºC (104ºF).

Site Requirements

The device is placed on a table-top. Before installing the unit, verify that the location chosen for installation meets the following site requirements.
• General — Ensure that the power supply is correctly installed.
• Power — The unit is installed within 1.5 m (5 feet) of a grounded, easily accessible outlet 100-250 VAC, 50-
60 Hz.
• Clearance — There is adequate frontal clearance for operator access. Allow clearance for cabling, power
connections and ventilation.
• Cabling — The cabling is routed to avoid sources of electrical noise such as radio transmitters, broadcast
amplifiers, power lines and fluorescent lighting fixtures.
• Ambient Requirements — The ambient unit operating temperature range is 0 to 40ºC (32 to 104ºF) at a rel-
ative humidity of up to 95%, non-condensing. Verify that water or moisture cannot enter the device casing.

Installing the Device

Installing the Device
The device can be installed on a flat surface or mounted in a rack. This section includes the following topics:
• Desktop or Shelf Installation
• Rack Installation

Desktop or Shelf Installation

When installing the switch on a desktop or shelf, the rubber feet included with the device should first be attached. Attach these cushioning feet on the bottom at each corner of the device.
Ensure the surface is be able to support the weight of the device and the device cables.
To install the device on a surface, perform the following:
1. Attach the rubber feet on the bottom of the device. The following figure illustrates the rubber feet installation
on the device.
Figure 18: Installing Rubber Feet
2. Set device down on a flat surface, while leaving 2 inches on each side and 5 inches at the back.
3. Ensure that the device has proper ventilation by allowing adequate space for ventilation between the device
and the objects around the device.

Rack Installation

The device can be mounted in an EIA standard-sized, 19-inch rack, which can be placed in a wiring closet with other equipment. To install, the device the mounting brackets must first be attached on the devices’s sides.
Page 27
DXS/DWS 3200 Series User Guide
Notes
• Disconnect all cables from the unit before mounting the device in a rack or cabinet.
• When mounting multiple devices into a rack, mount the devices from the bottom up.
To install the device in a rack, perform the following:
1. Place the supplied rack-mounting bracket on one side of the device ensuring the mounting holes on the device line up to the mounting holes on the rack mounting bracket. The following figure illustrates where to mount the brackets.
Figure 19: Attaching the Mounting Brackets
2. Insert the supplied screws into the rack mounting holes and tighten with a screwdriver.
3. Repeat the process for the rack-mounting bracket on the other side of the device.
4. Insert the unit into the 19-inch rack ensuring the rack-mounting holes on the device line up to the mounting hole on the rack. The following figure illustrates lining up and mounting the device in the rack.
