To install the 2E4X-27 in a 19-inch rack, Cabletron Systems includes an
accessory kit containing the rackmount brackets, mounting screws, and a
strain-relief bracket for cable management.
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 2E4X-27.
WARNING
Before installing the 2E4X-27 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.
