How to Install ORv3-Compliant QFX5241-64OD and QFX5241-64QD Switches with Tray Assembly (2OU) in Your ORv3 Rack

Use the information to install the Open Rack V3 compliant QFX5241-64OD and QFX5241-64QD DC PSU switches with tray in an Open Rack V3.

The Open Rack V3 (ORv3) compliant switch with tray assembly is an optional accessory that can be purchased separately. The switch comes pre-assembled to the tray, making the installation process quick and straightforward.

Warning:

Use this ORV3 compliant tray only with the listed or certified Juniper product. Failure to comply may result in damage.

Unpack the ORv3 Compliant Switch with Tray

We ship the switch-tray assembly in a cardboard carton, secured with foam packing material.

CAUTION:

The switch-tray assembly has maximum protection inside the shipping carton. Do not unpack the switch until you are ready to begin installation.

To unpack the switch-tray assembly:

Move the shipping carton to a staging area as close to the installation site as possible. Make sure that you have enough room to remove the system components.
Position the carton so that the arrows are pointing up.
Open the top flaps on the shipping carton.
Remove the accessory box and verify the contents in it against the parts inventory on the label attached to the carton.
Pull out the packing material holding the assembly in place.
Verify the chassis components received against the packing list included with the switch-tray assembly.
Save the shipping carton and packing materials in case you need to move or ship the switch-tray assembly later.

The IT Gear Input Connector in the switch-tray assembly is pre-installed with the DC power cords of the QFX5241-64OD and QFX5241-64QD switches. The power cords are pre-inserted into the DC PSU faceplate.

Note:

The two DC PSUs and four fans in the switch-tray assembly are hot-swappable and redundancy is supported. See Maintain the QFX5241-64OD-DO-T2 and QFX5241-64QD-DO-T2 Power System and Maintain the QFX5241-64OD-DO-T2 and QFX5241-64QD-DO-T2 Cooling System.

Install Switch-Tray Assembly in an ORv3 Rack

Before installing the switch-tray assembly in an ORv3 rack:

Verify that the site meets the requirements described in the site preparation checklist of the switch.
Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the building structure.
Read General Safety Guidelines and Warnings, with particular attention to Chassis and Component Lifting Guidelines.

To install the switch-tray assembly in an ORv3 rack:

Remove the tray assembly from shipping carton. See Figure 1.

Figure 1: Switch-Tray Assembly
Place the switch-tray assembly on a flat, stable surface.
Align the rails and secure it in place on your ORv3 rack.

Note: Rails are not provided with the switch-tray assembly.
Carefully align the switch-tray assembly with the rails in the rack. See Figure 2.

Figure 2: Align the Switch-Tray Assembly with the Rails
Slide the switch-tray assembly into the rack until the IT Gear Input Connector at the rear of the switch-tray assembly fully engages with the bus bar. See Figure 3.

Figure 3: Slide the Switch-Tray Assembly into the Rack

Note:
The bus bar delivers power to the switch.

When the switch-tray assembly is fully inserted in the rack, the latch locking tabs behind the rack's rail secure the switch-tray assembly in place. See Figure 4.
Figure 4: Fully Inserted Switch-Tray Assembly

Note:
For the switch-tray assembly installed in an ORv3 rack, you do not require an additional grounding or power configuration. The ORv3 rack infrastructure provides integrated power delivery and grounding. Ensure you install and ground the rack properly according to site standards.

Note: The standard ORv3 rack used with the QFX5241-64OD and QFX5241-64OD switch-tray assemblies deliver an output voltage of -48 V DC to -50 V DC.

Uninstall the Switch-Tray Assembly from the ORv3 Rack

To uninstall the ORv3 compliant switch with tray assembly from the ORv3:

Locate the latch locking tabs on both sides of the tray assembly.

Figure 5: Locate the Latch Locking Tabs
Push the latch locking tabs inward on both sides to release the switch-tray assembly from the rack post and gently slide the switch-tray assembly out of the ORv3 rack at same time.
Note:
Do not release the latch locking tabs before pulling the switch-tray assembly out. Both actions must be done simultaneously.
Gently slide the tray assembly out of the ORv3 unit.

Note: Sliding the tray out disconnects the power supply to the switch-tray assembly.

Ground the Switch-Tray Assembly

Note:

To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the ORv3 rack to the earth ground.

You do not need to make any external connections to ground the switch-tray assembly. The switch-tray assembly is connected to earth ground when you slide in the tray.

The switch-tray assembly gets earth ground protection by virtue of these features:

In the switch-tray assembly, the protective earthing terminal of the switch is connected to the tray using a grounding cable terminated with two–hole protective grounding lugs.
When the switch-tray assembly is completely inserted into the ORv3 rack, the ground contacts of the IT Gear Input Connector provide an electrically conductive path to the busbar and the rack frame.
The rack frame has dedicated grounding points typically located at the top of the rack. These grounding points help ground a loaded ORv3 rack.

Note:
You do not need separate grounding for your switch-tray assembly. The ORv3 rack infrastructure includes built-in grounding. Ensure the rack grounding is implemented according to site requirements. You do not need to take additional action for the switch.
