Chapter 2: Preparation

• Power Requirements: The switch requires one of these circuits:

— 100-240 VAC, 5.29-2.2 A, 50-60 Hz A.

— 40-72 VDC, 13.9–7.72 A.

Two circuits provide redundancy protection. Section 4.1 describes power cable requirements.

Important! 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 these 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.

Important! All power connections must be removed to de-energize the unit.

2.2 Tools Required for Installation

The following tools and equipment are required to install the switch:

• Phillips #1 screwdriver.

• Phillips #3 screwdriver.

• Four screws (two-post rack mount) that fit the equipment rack.

• Eight screws (four-post rack mount) that fit the equipment rack.

The accessory kit does not include screws for attaching the switch to the equipment rack. When

installing the switch into an equipment rack with unthreaded post holes, nuts are also required to

secure the switch to the rack posts.

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 antistatic 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.
