Chapter 3 Rack Mounting the Switch Important: The rack mounting procedure is identical for all switches covered by this guide. Illustrations in this chapter depict the mounting of a DCS-7020SR-32C2 switch. Les procédure de montage du bâti est identique pour tous les commutateurs visés par ce guide.
3.1.2 Inserting the Switch into the Rack This procedure attaches the switch to the rack (Figure 3-2). 1. Lift the chassis into the rack. Position the mounting ears against the rack posts. Note: The mounting ears should be at the same height to ensure that the device is level. 2.
Rack Mounting the Switch 2. Use the screws to attach the brackets to the chassis. Figure 4: Attaching Mounting Brackets to the Switch Chassis 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.
Page 16
Note: The rail clip prevents the extension of the rail beyond the maximum supported distance between the front and rear rack posts. Figure 6: Assembling the Rails 1 Rail Slide 3 Rail (assembled) 2 Rail Rod A Rack Plugs 2. Attach rail to the right rear rack post by inserting rod-end rack plugs into post slots (Figure 7: Attaching the Rails ).
Rack Mounting the Switch 3.2.3 Attaching the Switch to the Rack After the rails are installed, the switch slides on the rails into the rack. Each bracket includes a thumb screw that attaches the switch to the rail. 1. Lift the switch into the rack and insert the mounting brackets into the slide rails (Figure 8: Inserting the Switch onto the Rails).
Chapter 4 Cabling the Switch The following topics are covered in this section: • Grounding the Switch • Connecting Power Cables • Connecting Serial and Management Cables Grounding the Switch After mounting the switch into the rack, connect the switch to the data center ground. Figure 4-1 displays the location of the grounding lug on the front, left mounting ear for the DCS-7020SR-32C2 Important: Grounding wires and grounding lugs (M4 x 0.7) are not supplied.
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. The switch operates with two installed power supplies. At least one power supply must connect to a power source.
Cabling the Switch 4.2.2 DC Power Supplies The PWR-400-DC power supply is supported. The following figure displays a PWR-400-DC power supply. It connects to a circuit that provides the required power, as specified by Table 5: Switch Specifications (Power Draw). Figure 12: DC Power Supply (PWR-400-DC) 1 Status LED 3 PSU Handle...

1. Attach an ESD grounding strap. 2. Prepare the stranded copper wiring for the power supply to be used. Table 6: Wiring, Lug, and Tightening Torques for DC PSUs provides wiring, lug, and tightening torque information for the power supplies covered in this guide. Table 6: Wiring, Lug, and Tightening Torques for DC PSUs Wire Size Lug Type...
Cabling the Switch Assurez-vous de pouvoir retirer des circuits en courant continu avant d’effectuer toute action d’installation.Localiser les disjoncteurs ou fusibles sur les lignes électriques DC entretien des circuits. Mettez hors tension le circuit ligne ou retirer les fusibles. Important: Wire size must comply with local and national requirements and electrical codes.

Chapter 5 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.
Page 26
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.
Appendix A Status Indicator LEDs The following topics are covered in this section: • System-Level Status Indicator LEDs • Component Status Indicators System-Level Status Indicator LEDs Status indicator LEDs are located on the chassis and on some of the components like PSUs and Fan modules.
Note: Arista fixed-form switches take approximately 5 to 10 minutes to boot completely. A.1.2 Fan Status Indicator LED Figure 15: System Status and Fan Status Indicators display the fan status LED for the system. Table 9: Fan Status Indicator LED States...
Status Indicator LEDs Component Status Indicators The following topics are covered in this section: • Fan Module Status LED • PSU Module Status LED A.2.1 Fan Module Status LED Each fan and power supply module has an LED that reports the module status. Fan module status LED is on the fan module (Figure 17: Fan Module Status LED ) and is different from the system-level fan...
