Chapter 2
Preparation
This chapter describes the initial setup and preparation for installing the switch.
This chapter includes the following topics:
•Site Selection
•Tools and Parts Required for Installation
•Electrostatic Discharge (ESD) Precautions
2.1 Site Selection
The following criteria should be considered when selecting a site to install the switch:
•Temperature and Ventilation: For proper ventilation, install the switch where there is ample airflow
to the front and back of the switch. The ambient temperature should not go below 0° or exceed
40°C.
Note: To prevent the switch from overheating, do not operate it in an area where the
ambient temperature exceeds 40°C (104°F).
•Rack Space: Install the switch in a rack or cabinet. The switch height is 1.74". The accessory kit
provides necessary equipment such as mounting brackets and screws required for the installation.
When mounting the switch in a partially filled rack, load the rack from bottom to top, with the
heaviest equipment at the bottom. Load the switch at the bottom if it is the only item in the rack.
•Power Requirements: Power requirements vary by switch and power supply model. Refer to
Specifications and for information regarding your specific system.
Note: The power input plug-socket combination must be accessible at all times; it provides
the primary method of disconnecting power from the system.
•Other Requirements: Select a site where liquids or objects cannot fall onto the equipment and
foreign objects are not drawn into the ventilation holes. Verify the following guidelines are met:
• Clearance areas to the front and rear panels allow for unrestricted cabling.
• All front and rear panel indicators can be easily read.
• Power cords can reach from the power outlet to the connector on the rear panel.
Note: All power connections must be removed to de-energize the unit.
2.2 Tools and Parts Required for Installation
Each switch provides an accessory kit that contains parts that are required to install the switch. In
addition to the accessory kit, the following tools and equipment are required to install the switch:
Additional Tools
• Screwdriver
• Screws or rack mounting nuts and bolts
7

2.3 Electrostatic Discharge (ESD) Precautions
Observe these guidelines to avoid ESD damage when installing or servicing the switch.
• Assemble or disassemble equipment only in a static-free work area.
• Use a conductive work surface (such as an anti-static mat) to dissipate static charge.
• Wear a conductive wrist strap to dissipate static charge accumulation.
• Minimize handling of assemblies and components.
• Keep replacement parts in their original static-free packaging.
• Remove all plastic, foam, vinyl, paper, and other static-generating materials from the work area.
• Use tools that do not create ESD.
8

Chapter 3
Mounting the Switch
This chapter provides the instructions to mount the switch.
This chapter includes the following topics:
•Two-Post Rack Mount
3.1 Two-Post Rack Mount
This section describes instructions for two-post rack mounting the switch.
To mount the switch in a rack, you need to assemble the mounting brackets to the chassis, then attach
the brackets to the rack posts. It includes:
•Attaching Mounting Brackets to the Chassis
•Inserting the Switch into the Rack
3.1.1 Attaching Mounting Brackets to the Chassis
This section describes the steps to attach mounting brackets to the switch chassis.
Figure 1: Attaching the Mounting Brackets
1 Flat head screw M4x6mm
2 L-bracket
Note: Ensure that there is about 1U rack spacing between the two devices on the rack.
1. Position the L-bracket by aligning with the chassis holes on both the sides of the switch and fix it
with M4x6mm flat head screws.
2. Secure the mounting brackets firmly to the switch.
9

3.1.2 Inserting the Switch into the Rack
This section describes the steps to insert the switch into the rack.
Figure 2: Inserting the Switch into the Rack
1 Screw M4x25mm (screw is not included in the kit)
2 L-bracket
Note: For more information regarding the screw size, refer to Screw Size Details
Note: For thermal purposes, make sure that there is 1RU clearance above the rack mount
bracket.
1. Lift the chassis, attached with L-brackets, into the rack.
2. Place the switch into the rack by aligning with the holes of the mounting bracket.
3. Position the flanges against the rack posts as shown in the above figure.
4. Attach the bracket flanges to the rack posts.
10

Chapter 4
Grounding the Switch
This section provides instructions for grounding the switch.
Normally, the functional grounding of the switch is achieved through the DC input connection. If you
would like to do additional grounding, follow the instructions below:
Figure 3: Grounding the Switch
1 Screw M4 (with washer)
2 Solder terminal lug
3 Grounding point
Note: Grounding wires and grounding lugs are not supplied with the product. The wire size
should meet local and national installation requirements.
Note: The earth connection must not be removed unless all supply connections are
disconnected.
1. Ensure the rack is properly grounded and is in compliance with ETSI ETS 300 253.
2. Verify that there is a good electrical connection to the grounding point on the rack (no paint or
isolating surface treatment).
3. Attach the solder terminal lug (not provided with the switch) to an 18 AWG minimum grounding wire
(not provided with the switch), and connect it to the grounding point on the rear panel of the switch.
4. Tighten the M4 screw to secure the lug to the grounding point.
5. Connect the other end of the wire to the nearby grounded surface.
