This document provides instructions to install a 1U, 1.5U, or 2U switch (or SAN Router) in a 19-in. (48.3 cm) EIA rack
using the Universal Four Post Rack Kit. The document is organized as follows:

Introduction

The supported switches are listed in Table 1. The switch can be installed so that the port side is either flush with the
front posts or recessed with the non-port side flush with the rear posts. A recessed position allows a more gradual
bend in the fiber-optic cables connected to the switch and less interference in the aisle at the front of the rack.

Installation requirements

ATTENTION

ATTENTION

Allow 15 to 30 minutes to complete this procedure. Note the following requirements to ensure correct installation
and operation:

• Provide space in a 19-in. (48.3 cm) EIA rack, as required for the switch type, with a minimum distance of 24 in.

(609.60 mm) and a maximum distance of 32 in. (812.80 mm) between the front and back posts.

• Verify that the additional weight of the switch does not exceed the rack weight limits.

• Ensure that an electrical branch circuit with the following characteristics is available:

- Required voltage and frequency as indicated in the hardware reference manual (200-230 VAC is always

preferred).

- Protection by a circuit breaker in accordance with local electrical codes.

- Supply circuit, line fusing, and wire size that conform to the electrical rating on the switch nameplate.

- Grounded outlet compatible with the power cord and installed by a licensed electrician.

• Ensure that all equipment installed in the rack is grounded through a reliable branch circuit connection. Do not

rely on a secondary connection to a branch circuit, such as a power strip.

• Ensure that the rack is mechanically secured to ensure stability.

• Ensure that the air temperature at the fan inlet is less than 40

• Ensure that the airflow available at the air vents meets the minimum requirements for the switch.

Install the switch with the airflow aligned with any other switches in the rack. Some switches have airflow running from
port side to fan side and others have the opposite arrangement. Make sure that the airflow for all switches moves in
the same direction to maximize cooling.

Installation procedure for flush-front mounting

ATTENTION

NOTE

The switch must be turned off and disconnected from the fabric during this procedure.

Although this document describes how to install single-height (1U) and double-height (2U) switches, the illustrations
show a single-height switch as a typical installation.

Complete these tasks to install the switch in a four-post rack:

• “Attaching the front brackets”

• “Attaching the bracket extensions to the switch”

• “Installing the switch in the rack”

• “Attaching the rear brackets to the extensions”

• “Attaching the rear brackets to the rack posts”
