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 on page 8 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 on page 4 and Table 1-4 on page 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’entrée doit être accessible en tout temps ; Il fournit 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.

• 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 être enlevées pour hors tension l’appareil.

2.2 Tools and Parts Required for Installation

Each switch provides an accessory kit that contains parts that are required to install the switch. In addition to the accessory kit, the following tools and equipment are required to install the switch:

Two-Post Rack

• Screws or rack mounting nuts and bolts.

• Screwdriver

Four-Post Rack (Tool-less)

Chapter 2: Preparation Electrostatic Discharge (ESD) Precautions

Four-Post Rack (Conventional)

• Screws or rack mounting nuts and bolts.

• Screwdriver

Accessory kit does not include screws for attaching the switch to the equipment rack. When installing the switch into an equipment rack with unthreaded post holes, nuts are also required to secure the switch to the rack posts.

2.3 Electrostatic Discharge (ESD) Precautions

Observe these guidelines to avoid ESD damage when installing or servicing the switch.

• Assemble or disassemble equipment only in a static-free work area.

• Use a conductive work surface (such as an anti-static mat) to dissipate static charge.

• Wear a conductive wrist strap to dissipate static charge accumulation.

• Minimize handling of assemblies and components.

• Keep replacement parts in their original static-free packaging.

• Remove all plastic, foam, vinyl, paper, and other static-generating materials from the work area.

• Use tools that do not create ESD.

3.2.2 Assembling the Rails onto the Equipment Rack

Rail-rods and rail-slides assemble into two identical rails. Each rail connects a front post to a rear post. When the rails are installed, the switch slides on the rails into the rack. Each bracket includes a screw that attaches the switch to the rail.

Each end of an assembled rail contains two rack plugs (Figure 3-8). The rails are installed into a rack by inserting the plugs into rack slots. When installing rails into posts with threaded or rounded holes, remove all plugs located on both sides of the assembled rails, then install the rails with bolts that fit the rack.

Figure 3-8: Attaching the Mounting Brackets to the Switch Chassis

1 Step 1 4 Bracket clip (attached) 2 Step 2 5 Bracket clip (aligned) 3 Step 3

This procedure attaches the rails to a four post rack: Step 1 Slide a rail-rod into a rail-slide (Figure 3-9) until the rail clip makes an audible click.

The rail clip prevents the extension of the rail beyond the maximum supported distance between the front and rear rack posts.

Four-Post Rack Mount Chapter 3: Rack Mounting the Switch

Step 2 Attach rail to the right rear rack post by inserting rod-end rack plugs into post slots

(Figure 3-10, Inset A). The slide assembly must be inside the right posts, relative to the left rack posts.

If the rack plugs were previously removed, use bolts to attach the rail to the rack.

Step 3 Attach the slide end of the rail to the front post by extending the rail end past the post, then

contracting the rail while guiding the rack plugs into the post (Figure 3-10, Inset B).

Step 4 Repeat step 1 through step 3 for the left posts. Ensure the rails are on the same horizontal

level.

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 4.1). 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: 7280 Series 1 RU-Gen 3 Data Center Switches 29

Page 34

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 [email protected]
