This section describes the initial set up and preparation for installing the routers. This section discusses the following topics:
- Site Selection
- Tools and Parts Required for Installation
- Electrostatic Discharge (ESD) Precautions
2.1 Site Selection
Consider the following criteria when selecting a site to install the router in a Data Center environment:
- Temperature and Ventilation: For proper ventilation, install the router with ample airflow to the front and back of the router. Important: To prevent the device from overheating, do not operate it in an area where the ambient temperature exceeds 104°F (40°C). Pour empêcher l’interrupteur de surchauffe, ne pas utiliser il dans une zone où la température ambiante est supérieure à 104°F (40°C).
- Airflow Orientation: The fans and PSUs determine the airflow direction through the router. The color of the visible handles or labels indicates the airflow direction.
- Red Handle: The red handle represents the air exit module. The following figure shows the airflow direction through the router with an air exit module. Figure 2-1: Air Exit Modules Orient the router so airflow goes from the cooler to the hotter aisle.
- Rack Space: Install the router in a 19" rack or cabinet. The accessory kit provides mounting brackets for two-post and four-post racks. When mounting the router in a partially filled rack, load the rack from bottom to top, with the heaviest equipment at the bottom. If the router is the only item in the rack, load it at the bottom.
- Power Requirements: Each router and power supply model has different power requirements. For information regarding your specific system, refer to Specifications.
Refer to the Cable the Router section for power cable requirements. Important: The power input plug-socket combination must be accessible at all times, as it provides the primary method of disconnecting power from the system. La combinaison de la puissance-prise d’entrée doit être accessible en tout temps; Il fournit le principal moyen de coupure d’alimentation du système. Important: All power connections must be removed to de-energize the device. Toutes les connexions d’alimentation doivent être enlevées pour hors tension l’appareil.
- 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 the following 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.

Arista routers ship from the factory in Zero Touch Provisioning (ZTP) mode. ZTP configures the router without user intervention by downloading a startup configuration file or a boot script from a location specified by a DHCP server. To manually configure an Arista router, bypass ZTP. The initial configuration provides one username (admin) that is accessible only through the console port because it does not have a password. When bypassing ZTP, access the router by logging in as admin, with no password, through the console port. Then, you can configure a password for admin and other password-protected usernames. The manual configuration procedure described below cancels ZTP mode, logs into the router, assigns a password to the admin, assigns an IP address to the management port, and defines a default route to a network gateway. As the router 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: 1. Connect the router to a power source (Cable the Router). Note: Arista fixed routers take approximately 5 to 10 minutes to boot completely. 2. Connect the console port to a computer (Connecting Serial and Management Cables). 3. Log into the router by typing admin at the login prompt. localhost login: admin 4. Cancel ZTP mode by typing zerotouch cancel Important: This step initiates the router to reboot. localhost> zerotouch cancel 5. After the router reboots, log into the router 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. In this example, the assigned password is "pxq123". localhost(config)# username admin secret pxq123 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 configuring the management port IP address, select the following command to access the router from a host using the address configured in Step 9. ssh admin@192.0.2.8 Refer to the Arista Networks User Manual for the complete router configuration information.

(NIM) Interface Capabilities This section describes interface capabilities like speed and Forward Error Correction (FEC). For additional information, see the EOS User's Guide. These capabilities are displayed with the following command: show interfaces <INTF> hardware default The speed/auto-negotiation depends on the MAC/P-capabilities, the front panel connector, and the type of transceiver inserted. The default capabilities of the Arista AWE-7230R-4TX-4S Enterprise WAN router are as follows: Ports Speed Auto-negotiation RJ45 (Et1/1-Et1/4) 1G/2.5G/5G/10G full duplex 1G/2.5G/5G/10G full duplex SFP (Et1/5-Et1/8) 1G/10G 1G/10G full duplex 1G full duplex When a transceiver is inserted, EOS recognizes the transceiver type. To see which types of transceivers are supported, refer to the Supported Transceivers. EOS decides the capable speed/auto-negotiation that both the hardware and the modules satisfy. To view the show commands and example outputs, refer to the Show Commands for Speed and Auto-negotiation Capabilities. When the interface does not have a speed configuration, EOS applies the default speed. On an RJ45 port, the default configuration is auto-negotiation enabled with 10G. On an SFP port, the default configuration is auto-negotiation disabled with 10G. Speed Configuration This section describes the configuration of interface speed and auto-negotiation. Interface speed and auto-negotiation are configured using the speed speed-lane-token command, as shown in the following examples: To configure 10G speed with auto-negotiation disabled: Arista(config-if-Et1/1)# speed 10g To configure 1G speed with auto-negotiation disabled: Arista(config-if-Et1/1)# speed 1g To configure 10G speed with auto-negotiation enabled:

When a transceiver is inserted, EOS recognizes the transceiver type. To see which types of transceivers are supported, refer to the Supported Transceivers. If the transceiver is supported, EOS decides the capable speed and auto-negotiation satisfied by both the hardware and the modules. To view the show commands and examples output, refer to Show Commands for Speed and Auto-negotiation Capabilities. When there is no speed configuration on the interface, EOS applies the default speed. On an RJ45 port, the default configuration is auto-negotiation, enabled with 10G. On an SFP port, the default configuration is auto- negotiation, disabled with 10G. Show Commands for Speed and Auto-negotiation Capabilities Supported speed and auto-negotiation are displayed by the following command when the transceiver is inserted: show interfaces <INTF> hardware Arista(config)# show int ET1/1 hardware Ethernet1/1 Model: AWE-7250R-16S-F Type: 10GBASE-SR Speed/duplex: 10G/full(default) Flowcontrol: rx-(off),tx-(off) Error correction: unsupported Supported Transceivers The onboard SFP ports support a wide range of 1G and 10G pluggable transceivers.

Interface Configuration and Behavior For details about the different transceivers, modules, and cables, visit https://www.arista.com/en/products/ transceivers-cables. Transceiver Configuration Command Support The first eight ports (ports 1-8) are subject to minor differences in transceiver configuration. The shut and no shut configuration commands may not use the SFP transceiver’s TX Disable control register software. Instead, the TX Disable hardware low-speed pin signal will always be used. This does not result in operational or behavioral differences for Arista Networks transceivers. The configuration commands transceiver frequency and transceiver channel are not supported on the first eight ports (ports 1-8). Front Panel Port LEDs When using the locator-led interface CLI command, the first eight port LEDs (ports 1-8) may flash at a different rate than the last eight port LEDs (ports 9-16). Caveats Auto-negotiation parallel detection on ports 1-8. Parallel detection is used on Arista AWE 7250R-16S Enterprise WAN router ports 1-8, where the port can auto-negotiation. This happens when the link partner might not support auto-negotiation, or the auto- negotiation is disabled on the router. In this condition, the port capable of auto-negotiation can determine if it should use auto-negotiation and can match the speed with the other router. Parallel detection is enabled by default and cannot be disabled. Links can come up with a mismatch in auto- negotiation configuration. If auto-negotiation is enabled on Arista AWE-7250R-16S Enterprise WAN router ports 1-8 but not on the link partner and links can be established, auto-negotiation status is successful.
