•

Temperature and Ventilation: For proper ventilation, install the switch where there is ample airflow

to the front and back of the switch. The 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: The fans direct air from the front panel to the rear panel. Orient the front panel

toward the cool aisle.

•

Rack Space Requirements: Table 4: Rack Space Requirements shows the rack space

requirements for each of the modular switches.

Note: The accessory kit provides the required mounting brackets or shelf for each switch.

•

Power Requirements: Arista switches require a minimum number of operating power supplies in

the top section of all chassis, AC or DC and for each power domain of switches with multiple power

domains. Refer to Power Supply Specifications for more details regarding your switch.

Important: DC cables should be protected with circuit overcurrent protection devices and

circuit disconnect means. To power off a unit, power must be disconnected from ALL power

cables.

DC câbles doivent être protégés avec dispositifs de protection de surintensité circuit

et moyens de déconnexion du circuit. Pour éteindre une unité, l'alimentation doit être

débranchée de TOUS les câbles d'alimentation.

•

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.

•

AC power cords can reach from the AC power outlet to the input connectors.

•

DC power cables can reach from the DC power distribution unit to the input connectors.

Tools and Parts Required for Installation

The following tools are required to install a modular switch:

•

Mechanical device capable of lifting chassis being installed (Table 1: Modular Switch

Specifications).

•

Torque reading nut driver (for DC power supplies).

•

#2 Phillips head screwdriver.

•

Torque reading screwdriver using #2 Pozidriv or 1/4" flat bit (Needed for PWR-2700-DC-R).
