JSA7800 Site Guidelines and Requirements

General Site Installation Guidelines for the JSA7800 Appliance

The following precautions can help you plan an acceptable operating environment for your JSA7800 appliance and avoid environmentally caused equipment failures:

  • For the cooling system to function properly, the airflow around the chassis must be unrestricted. Allow sufficient clearance between the front and back of the chassis and adjacent equipment. Ensure that there is adequate circulation in the installation location.

  • Follow the electrostatic discharge (ESD) procedures to avoid damaging the equipment. Static discharge can cause components to fail, either completely or intermittently over time.

Note:

Install the appliance only in restricted areas, such as dedicated equipment rooms and equipment closets, in accordance with Articles 110–16, 110–17, and 110–18 of the National Electrical Code, ANSI/NFPA 70.

JSA7800 Appliance Rack Requirements

The JSA7800 appliance is installed in a four-post rack.

Table 2 provides the details of requirements for rack size, clearance, airflow, spacing of mounting brackets and flange holes, and connecting to the building structure.

Table 2: Rack Requirements for the JSA7800 Appliance

Rack Requirement

Specifications

Size

A 19-in. (48.3 cm) rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association (http://www.eia.org).

Clearance

  • The outer edges of the mounting brackets extend the width of either chassis to 19-in. (48.3 cm).

  • The front of the chassis extends approximately 1.5-in. (3.8 cm) beyond the mounting ears.

Spacing of mounting bracket and flange holes

  • The appliance can be mounted in any rack that provides holes or hole patterns spaced at 2-U [3.5-in. (4.5 cm)] increments.

  • The mounting brackets and front-mount flanges used to attach the chassis to a rack are designed to fasten to holes spaced at rack distances of 2-U (3.5-in.).

  • The appliance can be mounted in any rack that provides holes or hole patterns spaced at 1-U [1.75 in. (4.5 cm)] increments.

  • The mounting holes in the mounting brackets provided with the appliance are spaced 1.25-in. (3.2 cm) apart (top and bottom mounting hole).

Connecting to the building structure

Always secure the rack in which you are installing the JSA7800 appliance to the structure of the building. If your geographical area is subject to earthquakes, bolt the rack to the floor. For maximum stability, also secure the rack to ceiling brackets.

Additional Hardware Requirements

Before installing your JSA7800 appliance, ensure that you have access to the following additional hardware components:

  • A serial console.

  • To make sure that your JSA data is preserved during a power failure, we recommend that all JSA appliances or systems running JSA software storing data (such as consoles, Event Processors, or Flow Processors) be equipped with an uninterruptible power supply (UPS).

We recommend that you install JSA on your LAN to ensure that it can communicate with your applicable resources, such as authentication servers, DNS servers, internal webservers through HTTP/HTTPS, external websites through HTTP/HTTPS (optional), the Juniper Networks update server through HTTP, network file system (NFS) file servers (optional), and client/server applications (optional).
