Install the QFX5700

• What’s in the Box?
  A QFX5700 switch is shipped with a Routing Control BoardCB, FEB, and two power supplies. Note that a DB-9 to RJ-45 cable or a DB-9 to RJ-45 adapter with a CAT5E copper cable is no longer included in the device package. If you require a console cable, you can order it separately with the part number JNP-CBL- RJ45-DB9 (DB-9 to RJ-45 adapter with a CAT5E copper cable).

• What Else Do I Need?
  Because of the size and weight of the switch, it is strongly recommended that you use a mechanical lift to install the QFX5700.

Install a Pre-Populated QFX5700 Using a Mechanical Lift

1. Review the ‘General Safety Guidelines and Warnings’ in the QFX5700 Hardware Guide.
2. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end to a site ESD point.
3. Using a Phillips screwdriver, remove the screw on each side of the chassis that holds the rear mounting-blades to the chassis.
4. Slide the mounting blades out of the channels.
5. Load the switch onto the lift, making sure it rests securely on the lift platform.
6. Using the lift, align the switch in front of the rack.
7. Carefully position the chassis in the rack until the holes of the front-mounting brackets align with the holes in the rack rails.
8. Starting from the bottom, insert 5 rack mounting screws into the front mounting bracket holes on each side of the rack and tighten them with a screwdriver.
9. On the rear of the chassis, slide the rear mounting blades into the channels on each side of the chassis until they contact the rack rails.
10. Starting from the bottom, insert 4 rack mounting screws into the rear mounting bracket holes on each side of the rack and tighten them with a screwdriver.

10.  Starting from the bottom, insert 4 rack mounting screws into the rear mounting bracket holes on each side of the rack and tighten them with a screw driver.
11. Check to see if the mounting screws are aligned on each slide of the rack and that the switch is level.

NOTE: If you have unused ports on RCB (Timing Ports 10MHz/1PPS IN/OUT) and FPC (Optical Ports), plug them using dust covers to prevent dust from entering the connectors.

Install an Empty QFX5700 Chassis

WARNING: The switch weighs approximately 250 lb (113 kg). You’ll need at least three people to help lift the chassis and mount it in the rack or cabinet. If you’re not using a mechanical lift, make sure the chassis is empty (contains only the midplane) before you lift it.

1. Remove all components from the chassis (if installed):
2. Remove the QFX5700 Routing and Control Board
3. Remove the QFX5700 Forwarding Engine Board
4. Remove the QFX5700 FPC
5. Remove the QFX5700 Fan Tray
6. Remove the AC/HVDC Power Supply
7. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the device.
8. Using a Phillips screwdriver, remove the screw on each side of the chassis that holds the rear mounting blades to the chassis.
9. Slide the mounting blades out of the channels.
10. With one person on each side, carefully lift the bottom of the chassis and position it in the rack so that the front brackets are aligned with the rack holes.
11. With two people continuing to support the chassis, have the third person install and tighten five mounting screws in the front mounting bracket holes on each side of the rack, starting from the bottom.
12. On the rear of the chassis, slide the rear mounting blades into the channels on each side of the chassis until the rear mounting brackets contact the rack rails
13. Install and tighten four mounting screws into the rear mounting bracket holes on each side of the rack, starting from the bottom.
14. Check to see that all mounting screws on each side of the rack are aligned and the switch is level.
15. If you have removed any pre-installed components, reinstall them:
16. Install a QFX5700 Routing and Control Board
17. Install a QFX5700 Forwarding Engine Board
18. Install a QFX5700 FPC
19. Install a QFX5700 Fan Tray
20. Install a AC/HVDC Power Supply/DC Power Supply

Power On

Now that you’ve installed your QFX5700 in the rack, you’re ready to connect it to power.

1. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the QFX5700.

2. Ensure that the power supplies are fully inserted in the chassis and the latches are secure.

3. Locate the AC power cords shipped with the QFX5700 switch; the cords have plugs appropriate for your geographical location.

4. Insert the coupler end of the power cord into the each AC power cord inlet on the AC power supply.

5. If the AC power source outlet has a power switch, turn it off.
   NOTE: The QFX5700 powers on as soon as you plug it in to power. There is no power switch.

6. Plug in each power cord to the AC power source outlet.

7. If the AC power source outlet has a power switch, turn it on.

8. Verify that the status LEDs on each power supply are lit green.

Step 2: Up and Running

IN THIS SECTION

• Plug and Play | 11
• Customize the Basic Configuration | 11

Now that the QFX5700 is powered on, let’s do some initial configuration to get it up and running on the network. It’s simple to provision and manage the QFX5700 using the CLI.

Plug and Play
The QFX5700 switch ships with factory-default settings that enable plug-and- play operation. These settings load as soon as you power on the QFX5700 switch.

Customize the Basic Configuration
You can easily customize the factory-default configuration using CLI commands. Initially, you’ll need to make changes through the console port. After you configure the management port, you can access the device using SSH to make additional configuration changes. You can revert to the factory-default configuration whenever you want.
Have the following information ready before you begin to configure custom settings for the switch:

• Hostname
• Root authentication password
• Management port IP address
• Default gateway IP address
• (Optional) SNMP read community, location, and contact information

1. Verify that your laptop or desktop PC has these default serial port settings:

2. Baud Rate—9600

3. Flow Control—None

4. Data—8

5. Parity—None

6. Stop Bits—1

7. DCD State—Disregard

8. Connect the console port on the QFX5700 to a laptop or desktop PC using an RJ-45 cable and RJ-45 to DB-9 adapter (not provided).
   NOTE: If your laptop or desktop doesn’t have a serial port, use a serial- to-USB adapter (not provided).

9. At the Junos OS Evolved login prompt, type root to log in. You don’t need to enter a password. If the software booted before you connected the laptop or desktop to the console port, you might need to press the Enter key for the prompt to appear.
   login: root

10. Start the CLI.
    root@% cli

11. Enter configuration mode.
    root> configure

12. Add a password for the root administration user account.

13. [edit]

14. root@# set system root-authentication plain-text-password New password: password

15. Retype new password: password

16. (Optional) Configure the name of the switch. If the name includes spaces, enclose the name in quotation marks (“ ”).

17. [edit]

18. root@# set system host-name host-name

19. Configure the IP address and prefix length for the management port on the switch.
    NOTE: Although the CLI permits you to configure two management Ethernet interfaces within the same subnet, only one interface is usable and supported at any point of time.

20. [edit]

21. root@# set interfaces re0:mgmt-0 unit 0 family inet address address/prefix-length

22. Create a routing instance.

23. [edit]

24. root@# edit routing-instances mgmt_junos

25. root@# set routing-instances mgmt_junos routing-options static route 0.0.0.0/0 next-hop 10.102.70.254

26. Configure the static routes to remote prefixes.

27. [edit]

28. root@# set routing-options static route remote-prefix next-hop destination-ip

29. Enable the management instance.

30. [edit]

31. root@# set system management-instance

32. Enable Telnet service if needed.

33. [edit]

34. root@# set system services telnet

35. NOTE: When Telnet is enabled, you can’t log in to the QFX5700 through Telnet using root credentials. Root login is allowed only for SSH access.

36. Enable SSH service.

37. [edit]

38. root@# set system services ssh

39. To allow users to log in to the switch as root through SSH, include the root-login statement.

40. [edit system services ssh]

41. root@# root-login (allow | deny | deny-password)

42. NOTE: By default, users are not allowed to log in to the switch as root through SSH.

43.  Commit the configuration. Your changes become the active configuration for the switch.

44. [edit]

45. root@# commit
