• Connecting Line Card Modules and Cables Cabling the Power Supplies Before you begin, refer to the Arista Networks document Compliance and Safety Guide available at: https://www.arista.com/en/support/product-documentation. Important: Power down the switch: Remove all power cords from the power inlets.
Each power supply includes a fan that maintains proper power supply temperature and cools the supervisor modules. The appendices display the location of components for all switches described in this guide. Figure 19: Supported Power Supplies shows the supported power supplies for the 7500N family of switches.
Le - 48V et câbles de batterie-retour sont une paire courir à côté de l'autre et doivent être à peu près la même longueur. 4.4.1 DC Power Supplies The 7500N Series chassis supports two DC power supplies. • PWR-3K-DC-RED Power Supply.
Cabling the Modular Switch Figure 22: PWR-3K-DC-RED Power Supply 1 Status LED 3 Ejector 5 -48V terminal 2 Ground terminal 4 RTN terminal 1. Prepare the stranded wiring, see Wire and Lug Preparation. 2. Attach the power cable to the supply terminals. 3.

Prepare the stranded wiring, see Wire and Lug Preparation. 2. Remove the clear plastic cover protecting the terminal studs on the adapter by lifting the small center tab while sliding the cover off the adapter.

Cabling the Modular Switch 1 Compression lugs 3 -48V 2 Compression lugs 4 RTN 5. Slide the cover over the terminal studs until it clicks into place. 1 Captive screw slots 6. Insert the adapter into the DC power supply.
7. Tighten the two captive screws (on the bottom of the adapter) to the power supply module. Torque screws with #2 Posidriv to 2 N-m (17.7 in.-lbs.). 8. Attach the power cable to the DC power source. Important: Apply the ground connection first during installation and remove last when removing power.
Power Supply Configurations , in the top section behind the supervisors. • For 8-slot and 12-slot chassis (grouped power supplies top and bottom), Arista recommends an equal number of power supplies in the top and bottom groups. • For the 16-slot chassis with two power domains, the power domain with the lowest number of power supplies prescribes the total power available, therefore, Arista recommends equal number of PSUs in each domain.
• Each supply is wired to one feed, either A, or B. • The recommended installation is to alternate A, B feeds. In a four supply system configuration, you would wire ABAB, left to right. • All power supply slots must be filled with a powered supply (A or B), or a blank (X), or a non- powered power supply.

Default switch settings include: • 9600 baud • No flow control • 1 stop bit • No parity bits • 8 data bits The DCS-7516-SUP supervisor cards must be installed in one of the two slots designated for them in the DCS-7516N switch as shown in Figure 27: DCS 7516N Supervisor Slots.
Flexion excessive peut endommager les câbles d'interface, en particulier les câbles optiques. Note: You must ensure that any open slots for modules, power supplies, etc. are covered by the appropriate “blank” plates. Check with your local Arista Networks representative if you have questions.
Chapter 5 Configuring the Modular 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 44
11. 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 Indicators The following topics are covered in this section: • Supervisor Module • Line Card Module Indicators • Fabric Status Indicators • Power Supply Status Indicators Supervisor Module While the front panel of each switch can house two supervisors, switch operations require only one. Supervisors display switch component status and contain Ethernet management and console ports.

Status Indicators Component Activity Status LEDs LEDs located below the vents and left of the input ports display summary indicators for power supplies, fabric modules, fans, and line cards. Table 11: Component Activity LED States interprets the states of these indicators. When error conditions are indicated, refer to LEDs on the specified modules to determine the condition’s source.
Line card has failed. The line card provides LEDs for each port module socket: • Each LED corresponds to a module. • A set of four LEDs correspond to each module. When the module is programmed as a 40G port, the first LED in the set reports status.
