Chapter 1 – Getting Started
Step 1-
Unpack and remove the device and the accessories from the shipping box. Please inspect the items for any
shipping damage.
Note that the illustrations shown in this guide apply to all Arista 7000 Family switches, unless stated otherwise.
Step 2-
Review the hardware installation and safety instructions that appear in this guide. The switch supports 100-
127V or 200-240V AC inputs at 50 or 60 Hz. You can connect to either AC power source.
Step 3-
Identify the serial console and management Ethernet ports and understand cabling needs. You only need to
connect one of the management Ethernet ports – the second port provides redundancy. The serial console
and management Ethernet ports are shown below. (Figure 1-1 and 1-2)
