Installing and Configuring the SAN Director 2/128 Site Planning and Safety Guidelines WARNING: A fully populated SAN Director 2/128 (two power supplies) weighs approximately 250 lbs (113 kg) and requires a minimum of two people and a hydraulic or assisted lift to install it. Do not use the any of the bays (such as the power supply or blower assembly bays) for leverage. To ensure adequate cooling, install the chassis with the nonport side facing the air-intake aisle. This prevents the fans from pulling in heated exhaust air. The following steps are required to ensure correct installation and operation: 1. Locate an area that is 14 rack units (14U) high, 29-inches deep, and 19-inches wide. (1U = 1.75 inches) 2. Position the SAN Director 2/128 with the nonport side facing the air-intake (cool) aisle. Note: The SAN Director 2/128 can be installed facing either direction, if serviceability and cooling needs are met. 3. Plan for cable management before installing the chassis (see "Managing Cables" on page 63). Cables can be managed in a variety of ways, such as by routing cables below the chassis, to either side of the chassis, through cable channels on the sides of the cabinet, or by using patch panels. If the cables will be routed below the chassis, leave a minimum of 3U of space below the chassis. Note: Placing the switch on the floor is not recommended because this would prevent using the cable management tray and would make cable routing difficult. 36 SAN Director 2/128 Installation Guide
