Prepare the Site for Installation
To prepare your site for installing a Cloud Services Gateway (CSG) 620h series 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 electrostatic discharge (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 CSG620h series appliance in a 19-inch four-post rack using slide rails. Table 1 lists the rack requirements.
Table 1: Rack Requirements for a CSG620h Series 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 CSG620h series appliances use a fanless design.
When planning your site for installing a CSG620h series appliance, ensure that adequate clearance is provided around the appliance to allow for natural convection and heat dissipation. Avoid installing the appliance in sealed enclosures without sufficient ventilation.
When placing a CSG620h series appliance on a desktop or mounting it on a DIN rail, ensure that the top cooling fans and side surfaces are not obstructed. Blocking airflow around the chassis can prevent heat from dissipating effectively, which may cause the appliance to overheat and shut down.
