Mounting the QFX5200-48Y

The QFX5200-48Y is available in AC and DC power models. Only mount QFX5200-48Y models in a four-post rack. This procedure

describes the installation into a four-post rack and connecting AC power. For DC connection procedures, see the complete

QFX5200-48Y hardware documentation at https://www.juniper.net/documentation/.

To install a Juniper Networks QFX5200-48Y, you need:

•Electrostatic discharge (ESD) grounding strap (not provided)

•One pair of front mounting brackets (provided)

•One pair of adjustable rear mounting blades (provided)

•One pair of rear mounting brackets to attach the mounting blades to the chassis (provided)

•Twenty black flat head screws to secure the mounting rails and mounting blades to the chassis (provided)

•Eight screws and cage nuts to secure the chassis and rack-mount kit to the rack (not provided)

•Two washer head Phillips screws to lock the mounting blades to the rear brackets (provided)

•Screwdriver appropriate for your rack-mounting screws (not provided)

•Two power cords with plugs appropriate for your geographical location (provided)

•RJ-45 cable and RJ-45 to DB-9 serial port adapter (provided)

•Management host, such as a PC laptop, with a serial port (not provided)

•Grounding cable and lug (not provided)

•Two Phillips screws with star washers to ground the chassis (provided) (For instructions to attach the grounding cable and lug

to earth ground, see the QFX5200 Hardware Guide.)

To mount the switch in a four-post 19-in. rack:

1. Attach the ESD grounding strap to your bare wrist and to a site ESD point.

NOTE: If you are mounting multiple units in the rack, mount the heaviest device at the bottom and mount the

others from bottom to top in order of decreasing weight. The QFX5200-48Y weighs between 20.78 lb (9.43 kg)

and 21.16 lb (9.6 kg) with power supplies and fans installed. Installing these devices in a rack or cabinet requires

two people to lift the switch and secure it to the rack.

2. Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the building

structure.

3. Determine whether the end with the field-replaceable units (FRUs) or the ports is to be placed at the front of the rack.

4. Align the holes in the front mounting bracket with the holes on the side of the chassis so that the bracket is flush with the port

panel. See Figure 1.

Figure 1: Align the Front Mounting Bracket and Secure with Screws

5. Using a Phillips screwdriver, attach the front mounting bracket to the switch using four of the flat head screws in the holes

closest to the port panel. Tighten the screws.

6. Repeat Steps 4 and 5 on the opposite side of the switch.

7. Align the holes in the adjustable mounting rail with the remaining holes in the chassis. The alignment should permit two screws

at mid-chassis and four screws nearest the power supplies. The adjustable blades fit standard racks between 22.05 in. (56 cm)

to 29.5 in. (75 cm).

8. Attach the adjustable mounting rail to the chassis using the Phillips screwdriver and six of the flat head screws. Tighten the

screws. See Figure 2.

9. Repeat Steps 7 and 8 on the opposite side of the switch.

10. Have one person grasp both sides of the unit, lift it, and position it in the rack so that the front mounting bracket is aligned with

the rack holes.

13. Ensure that the chassis is level by verifying that all the screws on the front of the rack are aligned with the screws at the back

of the rack.

14. Secure the mounting rails to the rear mounting brackets using the two washer head screws. Tighten the screws. See Figure 5.

15. Attach a grounding cable to earth ground and then attach it to the chassis grounding points. For full instructions, see Connecting

Earth Ground to a QFX5200 in the QFX5200 Hardware Guide.

Connecting Power to the Device

The device is supplied with two factory-installed power supplies. To connect power to an AC-powered switch:

1. If the AC power source outlet has a power switch, set it to the OFF (O) position.

2. Insert the coupler end of the power cord into the AC power cord inlet on the AC power supply faceplate.

3. Insert the power cord plug into the power source outlet.

4. If the AC power source outlet has a power switch, set it to the ON (|) position.

5. Verify that the AC and the DC LEDs are lit green and on steadily.

Performing the Initial Software Configuration for QFX5200 Switches

You must perform the initial configuration of the QFX5200 through the console port using the CLI or through Zero Touch Provisioning

(ZTP). In order to use ZTP to provision the device, you must have access to a Dynamic Host Control Protocol (DHCP) server, and

a File Transfer Protocol (anonymous FTP), Hypertext Transfer Protocol (HTTP), or Trivial File Transfer Protocol (TFTP) server

on which the software image and configuration files are stored. For more information about using ZTP for provisioning the device,

see Understanding Zero Touch Provisioning in the Installation and Upgrade Guide.

Before you begin connecting and configuring a QFX5200, set the following parameter values on the console server or PC:

•Baud Rate—9600

•Flow Control—None

•Data—8

•Parity—None

QFX5200-48Y Quick Start Guide

•Stop Bits—1

•DCD State—Disregard

To connect and configure the switch from the console:

1. Connect the console port to a laptop or PC using the supplied RJ-45 cable and RJ-45 to DB-9 adapter. The console (CON)

port is located on the management panel of the switch.

2. Log in as root. There is no password. If the software booted before you connected to the console port, you might need to press

the Enter key for the prompt to appear.

3. Start the CLI.

root@% cli

4. Enter configuration mode.

root> configure

5. Add a password to the root administration user account.

root@# set routing-options static route default next-hop address

8. Configure the IP address and prefix length for the switch management interface.

[edit]

root@# set interfaces em0 unit 0 family inet address address/prefix-length

CAUTION: Although the CLI permits you to configure two management Ethernet interfaces within the same

subnet, only one interface is usable and supported.

NOTE: On the QFX5200-32C, management ports em0 (labeled C0) and em1 (labeled C1) are found on the FRU

end of the switch. On the QFX5200-48Y, the management port em0 is the top right-hand RJ-45 port on the port

panel.
