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 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 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.

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.
Chapter 5
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 27
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

Maintenance and Field Replacement
E.1 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.
Note 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.
E.2 Power Supplies
The following steps are required when removing and replacing power supplies from a switch.
Note Only a representative power supply module is shown in Figure E-1. For the location of the power supply
on your switch, refer to Appendix D.
E.2.1 Removing a Power Supply
Step 1 Ground yourself with an ESD wrist strap.
Step 2 Power down the power supply to be removed by disconnecting the AC power cable.
