This section discusses the following topics:
- Site Selection
- Tools Required for Installation
- Electrostatic Discharge (ESD) Precautions
2.1 Site Selection
Consider the following criteria when selecting a site to install the switch: Floor Space: Install the switch in an area that provides adequate clearance for removing front and rear components. The following figure displays switch clearance requirements. Figure 2-1: Switch Component Removal Footprint The following table shows the clearance dimensions for the modular switches. Table 4: Clearance Requirements and Footprint Dimensions Clearance Requirements DimensionsSwitch A B C DCS-7358X4 25.4 cm (10 inches) 64.0 cm (25.2 inches) 55.9 cm (22.0 inches) DCS-7368X4 25.4 cm (10 inches) 64.0 cm (25.2 inches) 55.9 cm (22.0 inches) DCS-7289R3A 25.4 cm (10 inches) 76.7 cm (30.2 inches) 66.0 cm (26.0 inches)
- Temperature and Ventilation: For proper ventilation, install the switch with 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: Determine the airflow direction of the fan modules and power supply modules. Fan and power supply module handles indicate airflow direction. Note: Your switch configuration may not support all power supplies. The Rear Panels display power supply and fan module locations on the rear panel. Verify the airflow direction of all modules (all rear panel modules have the same color handles). Orient the switch to ensure the air intake modules face the cool aisle. Contact your sales representative if the airflow direction is incompatible with the installation site.
- Rack Space: Install the switch in a 19" rack or cabinet. The switch height depends on the switch model, as specified in Table 1: Modular Switch Specifications. Verify that the removal clearances (Table 4: Clearance Requirements and Footprint Dimensions ) provide adequate space for the power and data cables that connect to the switch. 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. The accessory kit provides mounting brackets for four-post racks. Two-post mounting racks are not supported.
- Power Requirements: Power requirements vary by switch. Refer to Table 2: DCS-7358X4, DCS-7368X4 Modular Switch and Component Power Specifications, and Table 3: DCS-7289R3A Modular Switch and Component Power Specifications for information regarding your specific system. Multiple circuits provide redundancy protection. The switch uses power cables that have an IEC-320 C19 plug. The accessory kit provides IEC-320 C19 to C20 power cables. Important: All power input plug-socket combinations must be accessible at all times; they provide the primary method of disconnecting power from the system. Toutes les combinaisons de fiche-prise d’entrée de puissance doivent être accessibles en tout temps; ils fournissent 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.
- AC power cords can reach from the AC power outlet to the connectors on the rear panel. Important: Disconnecting power to all input sockets is required to turn off the unit completely.

Arista switches ship from the factory in Zero Touch Provisioning (ZTP) mode. ZTP configures the switch without user intervention by downloading a startup configuration file or a boot script from a location specified by a DHCP server. To manually configure a switch, ZTP is bypassed. The initial configuration provides one username (admin) that is accessible only through the console port because it has no password. When bypassing ZTP, initial switch access requires logging in as admin with no password through the console port. Then, you can configure an admin password and other password-protected usernames. This manual configuration procedure cancels ZTP mode, logs into the switch, assigns a password to the admin, assigns an IP address to the management port, and defines a default route to a network gateway. 1. Provide power to the switch (Powering the Modular Switch). 2. Connect the console port to a PC (Connecting Serial and Management Cables). As the switch boots without a startup-config file, it displays this message through the console: The device is in Zero Touch Provisioning mode and is attempting to download the startup-config from a remote system. The device will not be fully functional until either a valid startup-config is downloaded from a remote system or Zero Touch Provisioning is cancelled. To cancel Zero Touch Provisioning, login as admin and type 'zerotouch cancel' at the CLI. localhost login: 3. Log into the switch by typing admin at the login prompt. localhost login: admin 4. Cancel ZTP mode by typing zerotouch cancel. IMPORTANT: This step initiates a switch reboot. localhost> zerotouch cancel 5. After the switch boots, log into the switch again by typing admin at the login prompt. Arista EOS localhost login: admin Last login: Fri Mar 15 13:17:13 on console 6. Enter global configuration mode. localhost> enable localhost# config 7. Assign a password to the admin username using the username secret command. localhost(config)# username admin secret pxq123 8. Configure a default route to the network gateway. localhost(config)# interface management 1/1
