XRE200 Site Guidelines and Requirements
Environmental Requirements and Specifications for EX Series Switches
The switch must be installed in a rack or cabinet housed in a dry, clean, well-ventilated, and temperature-controlled environment.
Ensure that these environmental guidelines are followed:
The site must be as dust-free as possible, because dust can clog air intake vents and filters, reducing the efficiency of the switch cooling system.
Maintain ambient airflow for normal switch operation. If the airflow is blocked or restricted, or if the intake air is too warm, the switch might overheat, leading to the switch temperature monitor shutting down the switch to protect the hardware components.
Table 1 provides the required environmental conditions for normal switch operation.

Install EX Series switches 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.
General Site Guidelines
Efficient device operation requires proper site planning and maintenance and proper layout of the equipment, rack or cabinet (if used), and wiring closet.
To plan and create an acceptable operating environment for your device and prevent environmentally caused equipment failures:
Keep the area around the chassis free from dust and conductive material, such as metal flakes.
Follow prescribed airflow guidelines to ensure that the cooling system functions properly and that exhaust from other equipment does not blow into the intake vents of the device.
Follow the prescribed electrostatic discharge (ESD) prevention procedures to prevent damaging the equipment. Static discharge can cause components to fail completely or intermittently over time.
Install the device in a secure area, so that only authorized personnel can access the device.
Site Electrical Wiring Guidelines
Table 2 describes the factors you must consider while planning the electrical wiring at your site.
You must provide a properly grounded and shielded environment and use electrical surge-suppression devices.
Avertissement Vous devez établir un environnement protégé et convenablement mis à la terre et utiliser des dispositifs de parasurtension.
Table 2: Site Electrical Wiring Guidelines
Site Wiring Factor | Guidelines |
|---|---|
Signaling limitations | If your site experiences any of the following problems, consult experts in electrical surge suppression and shielding:
|
Radio frequency interference | To reduce or eliminate RFI from your site wiring, do the following:
|
Electromagnetic compatibility | If your site is susceptible to problems with electromagnetic compatibility (EMC), particularly from lightning or radio transmitters, seek expert advice. Some of the problems caused by strong sources of electromagnetic interference (EMI) are:
|
Rack Requirements
You can mount the device on two-post racks or four-post racks.
Rack requirements consist of:
Rack type
Mounting bracket hole spacing
Rack size and strength
Rack connection to the building structure
Table 3 provides the rack requirements and specifications.
Table 3: Rack Requirements and Specifications
Rack Requirement | Guidelines |
|---|---|
Rack type | You can mount the device on a rack that provides bracket holes or hole patterns spaced at 1-U (1.75 in. or 4.45 cm) increments and meets the size and strength requirements to support the weight. A U is the standard rack unit defined by the Electronic Components Industry Association (http://www.ecianow.org). |
Mounting bracket hole spacing | The holes in the mounting brackets are spaced at 1-U (1.75 in. or 4.45 cm), so that the device can be mounted in any rack that provides holes spaced at that distance. |
Rack size and strength |
|
Rack connection to building structure |

Cabinet Requirements
You can mount the device in a cabinet that contains a 19-in. rack.
Cabinet requirements consist of:
Cabinet size
Clearance requirements
Cabinet airflow requirements
Table 4 provides the cabinet requirements and specifications.
Table 4: Cabinet Requirements and Specifications

Cabinet airflow requirements | When you mount the device in a cabinet, ensure that ventilation through the cabinet is sufficient to prevent overheating.

Clearance Requirements for Airflow and Hardware Maintenance for an XRE200 External Routing Engine
When planning the site for installing an XRE200 External Routing Engine, you must allow sufficient clearance around the device.
Allow at least 6 in. (15.2 cm) of clearance on the side between devices that have fans or blowers installed. Allow 2.8 in. (7 cm) between the side of the chassis and any non-heat-producing surface such as a wall. For the cooling system to function properly, the airflow around the chassis must be unrestricted. Figure 1 shows the airflow through the XRE200 External Routing Engine.
If you are mounting an XRE200 External Routing Engine on a rack with other equipment, or if you are placing it on the desktop or floor near other equipment, ensure that the exhaust from other equipment does not blow into the intake vents of the chassis.
Leave at least 24 in. (61 cm) both in front of and behind the external Routing Engine. For service personnel to remove and install hardware components, you must leave adequate space at the front and back of the external Routing Engine. NEBS GR-63 recommends that you allow at least 30 in. (76.2 cm) in front of the rack or cabinet and 24 in. (61 cm) behind the rack or cabinet.
