Preparation
2.1 Site Selection
Describes the location specifications.
The following criteria should be considered when selecting a site to install the switch:
•Temperature and Ventilation: For proper ventilation, install the switch where there is ample airflow
to the front and back of the switch. The ambient temperature should not go below 0° or exceed
40°C.
Important: To prevent the switch from overheating, do not operate it in an area where the
ambient temperature exceeds 40°C (104°F).
Pour empêcher l’interrupteur de surchauffe, ne pas utiliser il dans une zone où la
température ambiante est supérieure à 40°C (104°F).
•Airflow Orientation: Determine airflow direction of the four fan modules and two power supply
modules on the rear panel. Fan and power supply module handles indicate airflow direction:
•Blue Handle: Air Inlet module.
•Red Handle: Air Exit module.
Figure 1: Airflow Direction Labels and Handles displays fan and power supply module locations on the
rear panel. Their red handles indicate that they are air exit modules. Verify that each module has the
same airflow direction. Base the switch orientation on the airflow direction of the modules to assure the
air inlet is always oriented toward the cool aisle:
•Air Exit modules: orient the rear panel toward the hot aisle.
•Air Inlet modules: orient the rear panel toward the cool aisle.
If the airflow direction is not compatible with the installation site, contact your sales representative to
obtain modules that circulate air in the opposite direction.
•Rack Space: Install the switch in a 19" rack or cabinet. The switch height is 1 RU. The accessory
kit provides mounting brackets for two-post and four-post racks.
When mounting the switch in a partially filled rack, load the rack from bottom to top, with the
heaviest equipment at the bottom. Load the switch at the bottom if it is the only item in the rack.
•Power Requirements: Power requirements vary by switch and power supply model. Refer to
Table 3: Switch Specifications (Power Input) and Table 4: Switch Specifications (Power Draw) for
information regarding your specific system.
Two circuits provide redundancy protection. Grounding the Switch describes power cable
requirements.

4 Fan module 3 8 Fan module 4 status LED 12 PSU 1 status LED
Note: Handle or label color indicates airflow direction.
Important: The power input plug-socket combination must be accessible at all times; it
provides the primary method of disconnecting power from the system.
La combinaison de la puissance-prise d’entrée doit être accessible en tout temps ; Il fournit
le principal moyen de coupure d’alimentation du système.
•Other Requirements: Select a site where liquids or objects cannot fall onto the equipment and
foreign objects are not drawn into the ventilation holes. Verify these guidelines are met:
• Clearance areas to the front and rear panels allow for unrestricted cabling.
• All front and rear panel indicators can be easily read.
• Power cords can reach from the power outlet to the connector on the rear panel.
Important: All power connections must be removed to de-energize the unit.
Toutes les connexions d’alimentation doivent être enlevées pour hors tension l’appareil.
2.2 Tools and Parts Required for Installation
Each switch provides an accessory kit that contains parts that are required to install the switch.
In addition to the accessory kit, the following tools and equipment are required to install the switch:

Preparation
• Screwdriver
Accessory kit does not include screws for attaching the switch to the equipment rack. When
installing the switch into an equipment rack with unthreaded post holes, nuts are also required to
secure the switch to the rack posts.
2.3 Electrostatic Discharge (ESD) Precautions
Observe these guidelines to avoid ESD damage when installing or servicing the switch.
• Assemble or disassemble equipment only in a static-free work area.
• Use a conductive work surface (such as an anti-static mat) to dissipate static charge.
• Wear a conductive wrist strap to dissipate static charge accumulation.
• Minimize handling of assemblies and components.
• Keep replacement parts in their original static-free packaging.
• Remove all plastic, foam, vinyl, paper, and other static-generating materials from the work area.
• Use tools that do not create ESD.
