3.3.2 Rackmount Installation

To install the 2H258-17R in a 19-inch rack, Enterasys Networks includes a strain-relief bracket for

cable management and an accessory kit containing the rackmount brackets, and mounting screws

to attach the rackmount brackets and strain-relief bracket.

Guidelines for the Rackmount Installation

The installation site must be within reach of the network cabling and meet the requirements listed

below:

• An appropriate grounded power receptacle must be located within seven feet of the location.

• 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.

CAUTION: To ensure proper ventilation and prevent overheating, leave a minimum

clearance space of 5.1 cm (2.0 in) at the left, right, and rear of the 2H258-17R.

WARNING: Before installing the 2H258-17R into a rack, ensure that the rack supports

the device(s) without compromising the stability of the rack. Otherwise, personal injury

and/or equipment damage may result.
