Configuring the Modular 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.

  1. Provide power to the switch Cabling the Modular Switch.
  2. Connect the console port to a PC.

    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 with the username secret command. 
    localhost(config)# username admin secret pxq123

     

  8. Configure a default route to the network gateway. 
    localhost(config)# ip route 0.0.0.0/0 192.0.2.1

     

  9. Assign an IP address (192.0.2.8/24 in this example) to an Ethernet management port. 
    localhost(config)# interface management 1/1
localhost(config-if-Ma1/1)# ip address 192.0.2.8/24

     

  10. Save the configuration by typing write memory or copy running-config startup-config . 
    localhost# copy running-config startup-config

     

  11. 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.

Recommendations for Power Supply Usage

  • Use separate circuits (A & B) with required protection for each power supply.
  • Use the same PSU model when replacing a failed PSU. Any suitable alternative must be approved before using if the original model is no longer supported or available.
  • Unless your switch allows for mixing power supplies, do not mix power supply types.
  • Populate the PSU slots sequentially.
  • Valid redundancy configurations for each domain are described in Power Supply Redundancy section.

Power Supply Redundancy

Important:

Installation of this equipment must comply with local and national electrical codes. If necessary, consult with the appropriate regulatory agencies and inspection authorities to ensure compliance.

 

Installation de cet équipement doit être conformes aux codes électriques locaux et nationaux. Si nécessaire, consulter les organismes de réglementation appropriés et des autorités de contrôle pour assurer la conformité.

 

 

Important:

Read all installation instructions before connecting the system to the power source.

 

Lire toutes les instructions d'installation avant de brancher le système à la source d'alimentation.

 

 

Most installations will have redundant, dual, independent power feeds. Each independent power feed will be referenced as A and B.

The recommended installation is to wire each supply to independent power feed (A or B).

Each power supply includes a fan that maintains proper power supply temperature. The following appendices display the location of the following component on all switches described in this guide.

The Front Panel displays the front panel location of the supervisor modules and line cards.

The Rear Panel displays the rear panel location of switch card modules (not visible), fans, and PSUs.

 

Important:

This unit requires over-current protection.

 

Cet appareil nécessite de protection contre les surintensités.

 

 

Important:

Unused slots must be occupied or covered with a blank to ensure proper airflow through the chassis.

 

Les emplacements inutilisés doivent être occupés ou recouvert d'un blanc pour assurer la bonne circulation d'air dans le châssis.

  • Uplink Port: Use the relevant optics for connection.

Connecting Linecard Modules and Cables

Install required SFP, SFP+, QSFP+, QSFP100, OSFP, and QSFP-DD optic modules in linecard module ports Figure 6 - SFP or SFP+ Ports .

Figure 6. SFP or SFP+ Ports


 

Connect cables as required to linecard module ports. Supervisor and linecard module ejectors on the front of the chassis assist with cable management.

 

CAUTION:

Excessive bending can damage interface cables, especially optical cables.

 

Flexion excessive peut endommager les câbles d'interface, en particulier les câbles optiques.

 

 

Note: You must ensure that any open slots for modules, supervisors, linecards, etc. are covered by the appropriate “blank” plates. Check with your local Arista Networks representative if you have questions.
