2.1 Site Se lectionThe following crite ria should be cons idered when se lecting a s ite to ins ta ll the switch:

• Temperature and Ventilation: For proper ventila tion, ins ta ll the switch where there is ample a irflow to the front and back of the switch. The ambient tempera ture should not go be low 0° or exceed 40° C.

Important! To prevent the switch from overhea ting, do not opera te it in an a rea where the ambient tempera ture exceeds 40°C (104°F).

• Airflow Orientation: Dete rmine the a irflow direction of the four fan modules and two power supply modules on the rear pane l. Figure 2-1 on page 6 indica tes the loca tion of the a irflow direction labe l on the power supply modules . The fan module a irflow direction labe l is loca ted on the le ft s ide of the handle . The fan and power supply module handles a lso indica te the module a irflow direction:• Blue Handle : Air Inle t module .• Red Handle : Air Exit module .

Verify tha t each module has the same a irflow direction. Base the switch orienta tion on the a irflow direction of the modules to assure the a ir inle t is a lways oriented toward the cool a is le :

• Air Exit modules : orient the rear pane l toward the hot a is le .• Air Inle t modules : orient the rear pane l toward the cool a is le .

If the a irflow direction is not compatible with the ins ta lla tion s ite , contact your sa les representa tive to obta in modules tha t circula te a ir in the oppos ite direction.

• Rack Space: Ins ta ll the switch in a 19" rack or cabine t. The switch he ight is 1 RU. The accessory kit provides mounting bracke ts for two-pos t and four-pos t racks .

When mounting the switch in a partia lly filled rack, load the rack from bottom to top, with the heavies t equipment a t the bottom. Load the switch a t the bottom if it is the only item in the rack.

• Power Requirements : The switch requires one of these circuits :• 100-240 VAC, 5.29-2.2 A, 50-60 Hz A.• 40-72 VDC, 13.9–7.72 A.

Two circuits provide redundancy protection. Section 4.1 describes power cable requirements .

Chapter 5

Configuring the SwitchAris ta switches ship from the factory in Zero Touch Provis ioning (ZTP) mode . ZTP configures the switch without user inte rvention by downloading a s ta rtup configura tion file or a boot script from a loca tion specified by a DHCP server. To manually configure a switch, ZTP is bypassed. The initia l configura tion provides one username (admin) access ible only through the console port because it has no password.

When bypass ing ZTP, initia l 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 configura tion procedure cance ls ZTP mode , logs into the switch, ass igns a password to admin, a ss igns an IP address to the management port, and defines a default route to a ne twork ga teway.

Step 1 Provide power to the switch (Section 4.1).

Step 2 Connect the console port to a PC (Section 4.2).

As the switch boots without a s tartup-config file , it displays the following through the console :

The device is in Zero Touch Provisioning mode and is attempting todownload the startup-config from a remote system. The device will notbe fully functional until either a valid startup-config is downloadedfrom a remote system or Zero Touch Provisioning is cancelled. To cancelZero Touch Provisioning, login as admin and type 'zerotouch cancel'at the CLI.

localhost login:

Step 3 Log into the switch by typing admin a t the login prompt.localhost login:admin

Step 4 Cance l ZTP mode by typing zerotouch cance l. IMPORTANT: This s tep initiates a s witch reboot.

localhost>zerotouch cancelStep 5 After the switch boots , log into the switch aga in by typing admin a t the login prompt.

Arista EOSlocalhost login:adminLast login: Fri Mar 15 13:17:13 on console

Step 6 Enter globa l configura tion mode .localhost>enablelocalhost#config

Step 7 Assign a password to the admin use rname with the us ername s ecret command.localhost(config)#username admin secret pxq123


Configuring the Switch

Step 8 Configure a default route to the ne twork ga teway.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 Etherne t management port.localhost(config)#interface management 1localhost(config-if-Ma1)#ip address 192.0.2.8/24
