Prepare the Site for Installation

To prepare your site for installing a Cloud Services Gateway (CSG) 2500 appliance, follow the guidelines and requirements listed in this article.

Site Preparation Guidelines

  • Install the appliance in an enclosed and secure environment, and allow only authorized personnel to access the device.
  • Keep the area around the appliance free from dust.
  • Follow ESD prevention procedures to avoid any damage to the appliance.

Environmental Requirements

  • Ensure that the area in which you operate the appliance has adequate air circulation so that the cooling system functions normally. Ambient air temperature may not be sufficient to cool the chassis to acceptable operating temperatures without adequate circulation.
  • Avoid temperature extremes.
  • High humidity conditions can cause moisture to penetrate into the chassis. The appliance can operate in relative humidity of 10% to 85%, non-condensing.

Rack Requirements

You can mount a CSG2500 appliance in a 19-inch four-post rack using slide rails. Table 1 lists the rack requirements.

Table 1: Rack Requirements for a CSG2500 Appliance

Requirement Guidelines
Rack type Use a 19-inch four-post rack that has bracket holes spaced at 1 U (1.75 in. or 4.45 cm) increments, and that has panels strong enough to support the weight of the appliance.
Rack size Comply with the size and strength standards of a 19-inch rack. Ensure that the rack rails are spaced wide enough to accommodate the external dimensions of the appliance chassis. Ensure that the spacing of rails and the adjacent racks allow for proper clearance around the appliance and the rack.
Rack firmly secured to building structure Secure the rack to floor brackets and to ceiling brackets to ensure maximum stability.

Airflow Requirements

The CSG2500 series appliances have 2+1 redundant fans, which are hot swappable in the field. The fans provide front-to-back cooling.

When placing a CSG2500 series appliance on a desk, ensure that there is space on the rear side of the appliance to allow air to exit from the fan. Also ensure that the vents on the side of the unit are never blocked, to allow hot air to flow out of the appliance. Covering the vents prevents heat from dissipating out of the appliance, which can cause the chassis to overheat and then shut down.
