Rack Mounting an Arista NDR Appliance

 

This section discusses the rack mounting procedure identical to all Arista NDR appliances covered by this guide. Illustrations in this section depict the mounting of1RU and 2RU appliances.

The following sections provide instructions for mounting 1RU and 2RU appliances:

Installing 1RU Arista NDR appliances

Perform the following steps to install a 1RU Arista NDR appliance:
  1. Identify the left and right outer rails by examining the ends, which bend outward. Slide the matching inner rails into the corresponding outer rails to be sure they are ready for installation.
     
    Note: The rail set fits a four post rack with a depth of between 25.6 and 33 in.

     

     

  2. Position the alignment pins in the rear rail (2) with the hole at the end of the slot in the front rail (1), and slide the front section into the rear section (3).

    Note: Each end of the assembled outer rail includes a bracket with alignment pins to fit into your rack holes.

     

     

  3. Position the alignment pins on the front end of the rail with the holes on the front of the rack (C). Push the rail into the rack until the quick-release bracket snaps into place, securing the rail to the rack.
     
    Note: Mount the rails horizontally, referencing the number labels on the rack's vertical bars.

     

     

  4. Adjust the rail to reach just past the full depth of your rack.
  5. Position the alignment pins on the rear end of the rail to the holes on the rack (D) and push the rail into the rack until the quick-release bracket snaps into place, securing the rail to the rack.
  6. Repeat the procedure for the other outer rail assembly.

    Note: Ensure that the appliance includes the inner rails and inner rail extensions and that the outer rails are installed on the rack.

     

     

  7. Align the appliance's inner rails with the front of the outer rails on the rack.
  8. Slide the appliance rails into the rack, keeping the pressure even on both sides.

    Note: You may have to select the bracket clips while inserting the appliance. When you fasten the server into the rack, ensure you hear the bracket clip engage with an audible click.

     

     

  9. Secure the front of the server to the rack with thumbscrews.

Installing 2RU Arista NDR Appliances

 

Perform the following steps to install a 2RU Arista NDR appliance:

Installing S40 1RU Arista NDR Appliances

 

Perform the following steps to install the S40 1RU Arista NDR appliance:
  1. Pull the inner rails out of the rack until they lock into place.

     

  2. Locate the rear rail standoff on each side of the system and lower them into the rear J-slots on the slide assemblies.
  3. Rotate the system downward until all the rail standoffs are seated in the J-slots.

     

  4. Push the system inward until the lock levers click into place.
  5. Pull the blue slide release lock tabs forward on both rails and slide the system into the rack until the system is in the rack.

     

Installing the S40 Arista NDR Appliance Bezel

 

Perform the following steps to attach the Arista bezel to the front of the enclosure.

  1. Align and insert the tabs on the bezel into the slots on the system.

     

     

     

  2. Press the bezel until the release button clicks in place.
  3. Lock the bezel.

Installing the Cable Management Arms

 

If you plan to use the Cable Management Arms (CMA), install the CMAs after installing the enclosure in the rack.

Perform the following steps to install the CMAs:

  1. Install two CMA attachment brackets on the left rails.

     

  2. Install two CMA attachment brackets on the right rails.

     

  3. Perform the following steps to install the upper CMA:
    1. On the right side of the rear of the enclosure, align the two connectors on the CMA with the attachment brackets on the rails.
    2. Insert the CMA connectors into the brackets until you hear an audible click.
    3. Swing the extension arm and align it with the left rail bracket.
    4. Insert the connector on the CMA to the attachment bracket on the left rail.

     

  4. Perform the following steps to install the lower CMA:
    1. On the left side of the rear of the enclosure, align the two connectors on the CMA with the attachment brackets on the rail.
    2. Insert the CMA connectors into the brackets until you hear an audible click
    3. Swing the extension arm and align it with the right rail bracket.
    4. Insert the connector on the CMA to the attachment bracket on the right rail.

Installing STR 4RU Arista NDR Appliances

 

Perform the following steps to install the STR 4RU Arista NDR appliance:
  1. Remove the inner rails from the rail kit and install them on the chassis.
  2. Pull the inner rails forward and remove it out from the rail kit.
     
    1 Tab 2 Inner rails 3 Outer rails

     

  3. Push the tab and slide the middle rails back until they lock into place.
  4. Attach the inner rails to the chassis by aligning the keyhole on the rail with the standoffs on the chassis and sliding forward until they lock into place.
    Note: Verify all the keyholes on the rails are aligned with the rail standoffs on the chassis. Improper installation of the rails may damage the rails or cause the chassis to fall when extended.

     

     

  5. Secure the rails by installing two screws on each side of the enclosure.

     

  6. Identify the rack holes for installing the rails and install the provided nuts on them. Use square or circular nuts depending on the type of rack post. Attach the right rail to the back post of the rack.

     

    1. Align the right rail with the holes on the back post of the rack.
    2. Push the rail back while holding the latch open.
    3. Once the rail engages to the rack post, release the latch to lock the rail in place.
    4. Insert the screws and secure the rail to the back post.
  7. Attach the right rail to the front post of the rack.

     

    1. Extend the rail to fit between the front and rear rack posts.
    2. Pull the rail backward to engage the rail to the rack post.
    3. Insert the screws and secure the rail to the front post.
  8. Repeat the previous steps to install the left rail.
  9. Pull the middle rails out of the rack until they lock into place. Ensure that the ball bearing retainer is located at the front of the middle rail.
  10. Lift the enclosure and slide it onto the rails.

     

  11. When hit a stop, pull the blue release tab on the inner rails.
  12. Secure the enclosure to the rack using the thumbscrews on the rack mount ears on both sides of the enclosure.

Installing STR Arista NDR Appliances Hard Disk Drives

 

Perform the following steps to install hard disk drives:

  1. Insert the drive into the drive carrier with the connector end of the drive at the back.
     
    1 Drive carrier 2 Drive 3 screws
  2. Install four screws to secure the drive to the drive carrier.
  3. Loosen the thumbscrews on the rack mount ears and pull out the enclosure from the rack.
  4. Loosen the two thumbscrews that attach the system cover to the chassis.
    Note: When you open the system cover, it must be closed within twelve minutes to prevent the enclosure from overheating.

     

     

  5. Pull the system cover forward and lift it out of the enclosure.

     

  6. Open the release handle on the drive carrier.
  7. Align the drive carrier with the target slot and gently push the drive carrier into the slot.
    Note: Consider the following ideal installation pattern for providing the best airflow and thermal performance:
    • Populate the slots from the rear of the enclosure first, closest to the PSU.
    • The minimum number of drives in an enclosure is 12.
    • If it is not possible to fill a complete row, insert drive blanks to fill the empty slots in each row.
    • Do not partially populate multiple rows. Fill each row before proceeding to the next row.

     

     

  8. Close the release handle to lock the drive in place.
  9. Verify that the activity light flashes to indicate that the spin-up sequence has begun.
