1. Meet the QFX5130-32CD
   The QFX5130-32CD Ethernet Switches are designed for spine-and-leaf deployments in enterprise, service provider, and cloud data centers. They come in a low- profile 1-U form factor and support a bandwidth of 12.8 Tbps. The switches have 32 400GbE ports and can be configured to support various speeds including 10-Gbps, 25-Gbps, 40-Gbps, 100-Gbps, and 400-Gbps. They are available with either a front-to-back or back-to-front airflow and dual AC power supplies.

2. Install the QFX5130-32CD
   To install the QFX5130-32CD, follow these steps:

3. Review the General Safety Guidelines and Warnings.

4. If you require a console cable, order it separately with the part number JNPCBL-RJ45-DB9 (DB-9 to RJ-45 adapter with a CAT5E copper cable).

5. Install the QFX5130-32CD in a four-post rack using the following steps:

6. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end to a site ESD point.

7. Decide which end of the switch you want to place at the front of the rack. Position the switch so that the AIR IN labels are next to the cold aisle and the AIR OUT labels are next to the hot aisle.

8. Attach the mounting rails to the sides of the switch using the twelve flat-head screws.

9. Lift the switch and position it in the rack. Line up the bottom hole in each mounting rail with a hole in each rack rail, making sure the switch is level.

10. While holding the switch in place, have a second person insert and tighten the rack mount screws to secure the mounting rails to the rack rails. Tighten the screws in the two bottom holes first, then tighten the screws in the two top holes.

11. Continue holding the switch in place and have the second person slide the mounting blades into the channel of the mounting rails.

12. Screw the mounting blades to the rack using the rack mount screws (and cage nuts and washers if your rack requires them).

13. Check that the mounting brackets on each side of the rack are level. If you have unused ports, plug them using dust covers to prevent dust from entering the switch.

Step 2: Up and Running

Now that the QFX5130-32CD 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 QFX5130 using the CLI.

Plug and Play
The QFX5130-32CD switch ships with factory-default settings that enable plug- and-play operation. The default settings enable the Link Layer Discovery Protocol (LLDP). These settings load as soon as you power on the QFX5130-32CD switch.

Customize the Basic Configuration

You can easily customize the factory-default configuration using CLI commands. Initially, you must 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:
  • Baud Rate—9600
  • Flow Control—None
  • Data—8
  • Parity—None
  • Stop Bits—1
  • DCD State—Disregard

  2. Connect the console port on the QFX5130-32CD to a laptop or desktop PC using an RJ-45 cable and RJ-45 to DB-9 adapter (not provided). The console (CON) port is located on the upper right corner of the port panel.
     NOTE: If your laptop or desktop doesn’t have a serial port, use a serial- to-USB adapter (not provided).

  3. At the Junos OS login prompt, type root to log in. You don’t need to enter a password. If the software boots before you connect your laptop or desktop PC to the console port, you might need to press the Enter key for the prompt to appear.

  4. Start the CLI.
     root@% cli

  5. Enter the configuration mode.
     root> configure

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

  • [edit]
  • root@# set system root-authentication plain-text-password New password: password
  • Retype new password: password

  7. (Optional) Configure the name of the switch. If the name includes spaces, enclose the name in quotation marks (“ ”).
     [edit] root@# set system host-name host-name

  8. Configure the IP address and prefix length for the management port on the switch. On the QFX5130-32CD, the management port re0:mgmt-0 is the lower RJ-45 port on the right side of the port panel and is labeled MGMT.
     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.
     [edit] root@# set interfaces re0:mgmt-0 unit 0 family inet address address /prefix-length

  9. Create a routing instance.
     [edit]

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

  10. Configure the static routes to remote prefixes.
      [edit] root@# set routing-options static route remote-prefix next-hop destination-ip

  11. Enable the management instance.
      [edit] root@# set system management-instance

  12. Enable Telnet service if needed.
      [edit] root@# set system services telnet
      NOTE: When Telnet is enabled, you cannot log in to the QFX5130-32CD through Telnet using root credentials. Root login is allowed only for SSH access.

  13. Enable SSH service.
      [edit] root@# set system services ssh

  14. To allow users to log in to the switch as root through SSH, include the root-login statement.
      [edit system services ssh] root@# root-login (allow | deny | deny-password)
      NOTE: By default, users are not allowed to log in to the switch as root through SSH.

  15. Commit the configuration to activate it on the switch.
      [edit] root@# commit
