Fast Track to Rack Installaon and Power
SUMMARY
This procedure walks you through the most basic
steps for installing your QFX5230-64CD switch in a
rack and connecng it to power.
IN THIS SECTION
Install the QFX5230-64CD Switch in a
Rack | 2
Connect to Power | 7
Install the QFX5230-64CD Switch in a Rack
Ensure that you have the following tools and parts available:
• An ESD grounding strap—not provided.
• A pair of side mounng brackets that aach to the chassis—provided with the rack mount kit.
• A pair of front and rear mounng rails that aach to the rack posts—provided with the rack mount
kit.
To mount the device on a four-post rack:
1. Place the switch on a at, stable surface.
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. To aach the side mounng brackets to the chassis, align the keyholes on the mounng brackets
over the shoulder screws on the chassis. Slide the mounng brackets toward the rear of the chassis.
2

Figure 1: Aach the Side Mounng Brackets
4. Assemble the mounng rails by sliding the rear oang rails into the front rails.
Figure 2: Assemble the Mounng Rails
5. Install the mounng rails on the rack.
6. Align the guide blocks of the rear mounng rails with the rear-post holes. Pull the rear mounng
rails toward the front of the rack to lock the rails in place. You will hear a disnct click sound when
the latch locks into the corresponding rack holes.
3

Figure 3: Install the Rear Mounng Rails
7. Align the guide blocks of the front mounng rails with the front-post holes. Push the front
mounng rails toward the rear of the rack to lock the rails in place. You will hear a disnct click
sound when the latch locks into the corresponding rack holes.
4

Figure 4: Install the Front Mounng Rails
8. Visually ensure that the front and rear latches are locked into place on the mounng rails. The
mounng rails should be securely installed on the rack.
Figure 5: Align the side mounng-brackets

9. Li the device and posion it in front of the rack, aligning the side mounng-brackets with the
mounng rails. Slide the device into the channels of the rack mounng rails
10. Push the chassis.

This topic describes the steps to connect an AC-powered QFX5230-64CD to power. To connect
QFX5230-64CD to power, complete the following:
Ground the QFX5230-64CD Switch
To ground the QFX5230-64CD switch, do the following:
1. Connect one end of the grounding cable to a proper earth ground, such as the rack.
2. Place the grounding lug aached to the grounding cable over the protecve earthing terminal on the
side panel.
7

Figure 8: Aach the grounding cable to QFX5230-64CD
3. Secure the grounding lug to the protecve earthing terminal using the 10-32 x .25-in. screws with
#10 split-lock washers.
4. Dress the grounding cable. Be sure that the cable doesn’t block access to or touch other device
components, and that it doesn’t drape where people could trip over it.
Connect the Power Cord and Power On the Switch
For informaon about the supported AC power cord specicaons, see Table 11 on page 32 .
To connect the power cord, do the following:
1. Ensure that the power supply is fully inserted in the rear panel of the switch and the latches are
secured.
8

2. If the AC power source outlet has a power switch, turn it o.
3. Plug in the power cord to the AC power source outlet.
4. Insert the power cord coupler in the power socket of the switch.
5. If the AC power source outlet has a power switch, turn it on. The switch powers on as soon as you
plug it in. The QFX5230-64CD doesn't have a power switch.
6. Check to see that the LED on the power supply is lit steadily green. If the LED stays o, disconnect
the power supply from the power source. You’ll need to replace the power supply.

QFX5230-64CD Switch Descripon
The QFX5230-64CD switch oers 64 ports of 400-Gbps in a 2-RU form factor. With 25.6 terabits per
second (Tbps) bandwidth, the QFX5230-64CD is an opmal choice for spine-and-leaf IP fabric
deployments as well as metro use cases. The QFX5230-64CD switch uses a Broadcom TH4 -
BCM56990 which is a high-radix class chip, dedicated for high-bandwidth network switching devices. It
provides support up to 64 × 400GbE, 128 × 200GbE, 256 × 100GbE, 256 × 40GbE, 256 × 25GbE, or
256 × 10GbE ports.
This is a high density 64 x 400G Metro Ethernet Switch designed for Data Center, Telco-Cloud, and
Enterprise for use in er 1 and er 2 leaf and spine in IP Fabric and as a spine and super-spine in EVPN-
VXLAN fabric and other applicaons.
An Intel 6-core Intel Hewi Lake D-1637 processor drives the QFX5230-64CD control plane, which
runs the Junos OS Evolved soware. The Junos OS Evolved soware image is stored on two internal
100-GB solid-state drives (SSDs). The QFX5230-64CD is available with ports-to-FRUs airow (AIR
OUT) and FRUs-to-ports airow (AIR IN), and with AC or DC power supplies.

NOTE: The 16 ports marked in green, from 33 through 63, denote the ports that support 400G-
ZR and 400G-ZRM QDD opcs. If these opcs are plugged into other ports, they don't funcon
and trigger an alarm.

System Soware
The QFX5230-64CD runs the Junos OS Evolved operang system. It provides several capabilies that
include Layer 2 and Layer 3 switching, roung, and security services. Junos OS Evolved soware is
installed on the solid-state drive (SSD) in the switch.
For more informaon about the features supported on QFX-5230-64CD devices, see Feature Explorer.
You can manage the switch using the Junos OS Evolved CLI, accessible through the console and out-of-
band management ports on the device.
QFX5230-64CD Component Redundancy
The following hardware components provide redundancy on a QFX5230-64CD switch:
• QFX5230-64CD power supply modules — The QFX5230-64CD models' power supply are eld-
replaceable units (FRUs) that can be removed and inserted hot. Installing or replacing the PSUs
doesn't need turning o the device or interfering with the switching process.
