Chapter 2 Preparing for Installation
Site Requirements
Environmental
Proper operation of the Cisco MGX 8950 switch depends on a proper environment. This section
describes environmental requirements for the site where you intend to install the Cisco MGX 8950
switch. The section describes the following requirements:
• Seismic Anchoring, page 2-11
• Shock, page 2-11
• Vibration, page 2-12
• Space, page 2-12
• Temperature, Altitude, and Humidity, page 2-15
• Ventilation, page 2-15
Seismic Anchoring
In order for you to secure a Cisco-supplied cabinet, the holes in the upper and lower corners
accommodate 3/8-inch or 1/2-inch bolts. Also, you can buy an optional stability plate with the Cisco
cabinet. The stability plate is bolted to the floor, and then the Cisco cabinet is bolted to the stability plate.
See
Chapter 3, “Installing a Cisco MGX 8950” for stability plate installation instructions.
Shock
For non-operating mechanical shock and for equipment weighing more than 100 pounds, the peak
acceleration will be between 20 - 25 G.
For operating mechanical shock, the minimum velocity change is 0.66 m/s with an effective free fall drop
height of 13 mm for MDVT and an effective free fall drop height of 25 mm for NEBS with no velocity
change specified.
