3.3INSTALLING THE 2E4X-27

The 2E4X-27 may be installed on a tabletop, shelf, or in a 19-inch rack. Section 3.3.1 describes a tabletop or shelf installation and Section 3.3.2 describes the rackmount installation.

To prevent possible personal injury and/or damage to the unit, do NOT connect power to the 2E4X-27 until instructed to do so.

3.3.1Tabletop or Shelf Installation

The following two subsections provide guidelines for installation on a tabletop or shelf.

Guidelines for Tabletop and Shelf Installations

Tabletop and shelf installations must be within reach of the network cabling and meet the requirements listed below:

•Locate the 2E4X-27 within seven feet of an appropriately grounded power receptacle that meets the power supply requirements listed in Appendix A.

•In a shelf installation, the shelf must support 13.6 kg (30 lb) of static weight for each 2E4X-27.

•Maintain a temperature of between 5°C (41°F) and 40°C (104°F) at the installation site with ﬂuctuations of less than 10°C (18°F) per hour.

•Maintain a 2-inch clearance from the left, right, and rear sides of the device to provide adequate ventilation.

Installation

For a tabletop or shelf installation, locate the 2E4X-27 within seven feet of its power source and with an unrestricted free surface area as shown in Figure 3-1. Proceed to Section 3.3.3 for 2E42-27/ 2E43-27 power connection instructions and to Section 3.3.4 for 2E42-27R/2E43-27R power connection instructions.

To ensure proper ventilation and prevent overheating, leave a

!minimum clearance space of 5.1 cm (2.0 in) at the left, right,

CAUTION	and rear of the 2E4X-27.
