Preparation

2.1

Site Selection
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 emp�cher l'interrupteur de surchauffe, ne pas utiliser il dans une zone o� la temp�rature ambiante est sup�rieure � 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 2-1 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 1-3 and Table 1-4 for information regarding your specific system.
Two circuits provide redundancy protection. Section 4.1 describes power cable requirements.

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'entr�e doit �tre accessible en tout temps ; Il fournit le principal moyen de coupure d'alimentation du syst�me.
� 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 �tre enlev�es pour hors tension l'appareil.

Configuring the Switch
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) 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 admin, assigns an IP address to the management port, and defines a default route to a network gateway.
Step 1 Provide power to the switch (Section 4.3).
Step 2 Connect the console port to a PC (Section 4.4).
As the switch boots without a startup-config file, it displays the following 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:
Step 3 Log into the switch by typing admin at the login prompt.
localhost login:admin
Step 4 Cancel ZTP mode by typing zerotouch cancel. IMPORTANT: This step initiates a switch reboot.
localhost>zerotouch cancel
Step 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
Step 6 Enter global configuration mode.
localhost>enable localhost#config

Quick Start Guide: 7050 Series 1 RU-Gen 3 Data Center Switches

Chapter 5: Configuring the Switch
Step 7 Assign a password to the admin username with the username secret command.
localhost(config)#username admin secret pxq123 Step 8 Configure a default route to the network gateway.
localhost(config)#ip route 0.0.0.0/0 192.0.2.1
Step 9 Assign an IP address (192.0.2.8/24 in this example) to an Ethernet management port.
localhost(config)#interface management 1 localhost(config-if-Ma1/1)#ip address 192.0.2.8/24 Step 10 Save the configuration by typing write memory or copy running-config startup-config. localhost#copy running-config startup-config When the management port IP address is configured, use this command to access the switch from a host, using the address configured in step 9: ssh admin@192.0.2.8 Refer to the Arista Networks User Manual for complete switch configuration information.

Note

Considerations
� All fans and power supplies are hot swappable. � The switch can be running while a power supply is being installed or removed, but the power supply
being replaced must not be connected to a power source. � All slots must be filled or covered with a blank for operation (even though power supply or fans may
not be functional). � Before you begin, refer to the Arista Networks document Safety Information and Translated Safety
Warnings available at: https://www.arista.com/en/support/product-documentation.
Descriptions for the removal and replacement of power supplies and fans are for a representative power supply or fan. Locations of status indicator LEDs may differ. Refer to the front and rear panel illustrations of your device to locate the appropriate LED.

Installing a Power Supply
You must make space for installing the power supply by removing an existing one (Section E.2.1). Step 1 Remove the replacement power supply from its packaging. Step 2 Slide the new power supply into the empty slot. Step 3 Slide the new power supply into the switch until the power supply is fully seated and the
release lever snaps into place (Figure E-1). Step 4 Connect the power cord to the power supply. Step 5 Verify the LED(s) on the power supply.
The Power Supply status LED should be a steady green for normal operation.
Step 6 Verify the new power supply operation by issuing the show environment power command.
switch#show environment power
The output of the command will list the power supplies in operation and should include the one you replaced.
Fan Modules
Hot swap fans within 30 seconds to prevent the switch from overheating. Ensure that the module you are replacing matches those already installed in the switch.
