Installing DC Power Supply

You must make space for installing the power supply by removing an existing one (Removing AC

Power Supply, Removing DC Power Supply) or removing a blank (Removing Power Supply Blank)

from a power supply slot available on the switch.

Perform the following steps to install a DC power supply.

1. Put on a grounded ESD strap.

2. Unbox the new power supply.

3. Insert the new power supply into the empty power supply slot.

4. After you insert the power supply, push gently on the power supply until the power supply is fully

seated.

5. Pull up on the handle on the power supply to lock the power supply in place.

6. Connect the cables for your power supply as explained in the guide (Cabling the DC Power

Supply).

Fabric and Fan Module (Fabric Module)

Note: For NEBS-compliant Service Provider installations, refer to Removing Service Provider

7500N Series Fan and Safety Guard. Contact your Arista representative if needed.

The fabric and fan modules are hot-swappable. They are accessible from the rear of the switch (Rear

Panel). You must take into account that the module you are inserting is compatible with the switch and

the module that you are replacing. Perform the following steps to remove and replace a fabric and fan

module, or a fan-only module, if your switch supports one.

F.2.1

Removing Fabric Module Blank

The fabric module blank is screwed on. Use the appropriate screwdriver for your switch.

1. Put on a grounded, anti-static ESD strap.

2. Unscrew the blank from the fabric module slot you are going to populate.

You may want to save the blank for future use as needed. The blank is needed for the switch to

operate normally if a fabric module slot is not populated.

F.2.2

Removing Fabric Module

1. Put on a grounded, anti-static ESD strap.

2. Loosen the two Phillips screws on the fabric module.

3. Pull out the ejector handle on the fabric module.

4. Pull the ejector handles outwards by 90 degrees to disengage the fabric module.

5. Pull on the ejector handles to remove the fabric module from the slot.

Note: Fabric modules can be heavier than 25 lbs. Provide adequate support while handling

them to prevent injury or damage.
