Only qualified personnel should install, service, or replace this equipment. 1.
Chapter 1: Overview 1.5 Obtaining Technical Assistance Any customer, partner, reseller or distributor holding a valid Arista Service Contract can obtain technical support in any of the following ways: • Email: support@aristanetworks.com. This is the easiest way to create a new service request. Include a detailed description of the problem and the output of “show tech-support”. • Web: www.aristanetworks.com/en/support. A support case may be created through the support portal on our website.
Chapter 2: Preparation Chapter 2 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).
Chapter 2: Preparation • 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. Important! The power input plug-socket combination must be accessible at all times; it provides the primary method of disconnecting power from the system.
Chapter 3: Rack Mounting the Switch 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-7124SX switch. The accessory kit provides components for installing the switch in two-post and four-post racks. • • Section 3.1 provides instructions for mounting the switch in a two-post rack. Section 3.2 provides instructions for mounting the switch in a four-post rack.
Chapter 3: Rack Mounting the Switch Refer to Figure 2 and Figure 3 for a description of the mounting brackets. The switch supports any mounting position into a two-post rack that meets the following conditions: • • The bracket flanges do not extend beyond the switch chassis. Three sets of screws attach each mounting bracket to the chassis. Figure 4 displays proper bracket mount configuration examples.
Chapter 3: Rack Mounting the Switch 3.1.1 Attaching Mounting Brackets to the Chassis To attach mounting brackets to the switch chassis, perform this procedure: Step 1 Align the mounting brackets with the chassis to obtain the desired mounting position. Step 2 Attach the brackets with six M4x5 flat head Phillips screws per bracket, using a #1 Phillips screwdriver. Space the screws evenly, separating them with the widest possible distance.
Chapter 3: Rack Mounting the Switch 3.2 Four-Post Rack Mount The switch is mounted onto a four-post rack by assembling two rails onto the rear posts, sliding the switch onto the rails, then securing the switch to the front post. The installation kit provides the following four-post mounting parts: • • • 2 mounting brackets 2 rails 12 M4x5 flat head Phillips screws Refer to Figure 2 and Figure 3 for a description of the mounting brackets.
Chapter 3: Rack Mounting the Switch 3.2.1 Attaching Mounting Brackets to the Chassis To attach mounting brackets to the switch chassis, perform this procedure: Step 1 Align the mounting brackets with the chassis to obtain the desired mounting position. Step 2 Attach the brackets with six M4x5 flat head Phillips screws per bracket, using a #1 Phillips screwdriver. Space the screws evenly, separating them with the widest possible distance.
Chapter 3: Rack Mounting the Switch 3.2.2 Assembling the Rails onto the Equipment Rack The rails attach to the rear rack posts to support the switch. Before attaching the rails to the rack posts, verify that, when the switch is mounted, the distance between the bracket flanges and rail flanges does not exceed 30 inches, as shown in Figure 11. Figure 11: Maximum Bracket-Rail Span To attach the rails to the rear rack post, perform this procedure: Step 1 Select mounting screws that fit your equipment rack.
Chapter 3: Rack Mounting the Switch 3.2.3 Attaching the Switch to the Rack Step 1 Lift the switch into the rack and insert the mounting brackets onto the rails. Figure 13: Inserting the Switch onto the Rails Step 2 Slide the switch on the rails, toward the rear posts, until the mounting bracket flanges are positioned on the rail posts. Step 3 Select mounting screws that fit the equipment rack. Each chassis side requires two screws.
Chapter 4: Cabling the Switch Chapter 4 Cabling the Switch 4.1 Connecting Power Cables Important! Installation of this equipment must comply with local and national electrical codes. If necessary, consult with the appropriate regulatory agencies and inspection authorities to ensure compliance. The switch operates with two installed power supplies. At least one power supply must connect to a power source. Two circuits provide redundancy protection.
Chapter 4: Cabling the Switch 4.1.2 DC Power Supply The DC power supply connects to a circuit that provides 40-72 VDC and 13.9–7.72 A. Figure 16 displays the DC power supply with the terminal cover in place (left illustration) and with the terminal cover removed (right illustration).
Chapter 4: Cabling the Switch Table 2 lists the pin connections of the RJ-45 to DB-9 adapter cable. Table 2: RJ-45 to DB-9 Connections RJ-45 DB-9 RJ-45 DB-9 RTS 1 8 CTS GND 5 5 GND DTR 2 6 DSR RXD 6 3 TXD TXD 3 2 RXD DSR 7 4 DTR GND 4 5 GND CTS 8 7 RTS The front panel contains the console, management, and USB ports. Figure 17 displays the ports on the 7124FX switch. Appendix C displays the front panel of all switches covered by this guide.
Chapter 5: Configuring the Switch 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.
