Unpacking and Mounting the ACX5048 and ACX5096 Routers

Unpacking an ACX5000 Router

The ACX5000 router chassis is a rigid sheet-metal structure that houses the hardware components. An ACX5000 router is shipped in a cardboard carton, secured with foam packing material. The carton also contains an accessory box and quick start instructions.

CAUTION:

ACX5000 routers are maximally protected inside the shipping carton. Do not unpack the router until you are ready to begin installation.

To unpack an ACX5000 router:

  1. Move the shipping carton to a staging area as close to the installation site as possible, but where you have enough room to remove the system components.
  2. Position the carton so that the arrows are pointing up.
  3. Open the top flaps on the shipping carton.
  4. Remove the accessory box and verify the contents against the inventory included in the box. Table 1 lists the inventory of components supplied with an ACX5000 router.
  5. Pull out the packing material holding the router in place.
  6. Verify the chassis components received:
    • Two power supplies

    • Fan modules:

      • Five fan modules for ACX5048

      • Three fan modules for ACX5096

  7. Save the shipping carton and packing materials in case you need to move or ship the router later.

Mounting an ACX5000 Router in a Rack or Cabinet

You can mount all ACX5000 routers on a four post 19-in. rack or cabinet using the mounting kit provided with the device. The ACX5096 router can also be installed on a two-post rack or cabinet. The mounting kit for the two-post installation is not provided with the router.

For four post rack or cabinet installations, the mounting kit contains two front mounting rails with two matching rear mounting blades. This configuration allows either end of the router to be mounted flush with the rack and still be adjustable for racks with different depths.

For ACX5048 routers, space the front and rear rack rails between 23 in. (58.5 cm) and 30.25 in. (76.8 cm) front-to-back.

The mounting kit for the ACX5096 has mounting rails, blades, and brackets for the four-post configuration.

The front and rear rack rails must be spaced between 28 in. (71.1 cm) and 36 in. (91.4 cm) front to back.

Before You Begin Rack Installation

Before you begin mounting a ACX5000 router in the rack or cabinet:

  1. Ensure that you understand how to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.
  2. Verify that the site meets the requirements described in Site Preparation Checklist for an ACX5000 Router.
  3. Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the building structure.
  4. Read General Site Guidelines, with particular attention to Chassis and Component Lifting Guidelines.
  5. Remove the router from the shipping carton. See Unpacking an ACX5000 Router.
  6. Ensure that you have the following parts and tools available to mount the router in a rack:
    Note:

    The ACX5000 routers can be installed on a four-post rack or cabinet. The mounting blades, rails, and the respective screws for the four-post installation comes with the ACX5000 routers.

    The ACX5096 router can also be installed on a two-post rack or cabinet. The mounting brackets and the respective screws for the two-post installation does not come with the ACX5096 router. You need to purchase it separately.

    • ESD grounding strap (not provided).

    • Blades, rails, or brackets (provided).

      • For four-post installations:

        • One pair of rear mounting blades. These mounting blades support the rear of the chassis and must be installed (provided).

        • One pair of front mounting rails. The mounting blades slide into the mounting rails to support the router (provided).

        • Screws to secure the mounting rails to the chassis (provided).

          • Twelve screws for ACX5048

          • Twenty-four screws for ACX5096

        • Eight screws to secure the chassis and rear installation blades to the rack (not provided).

      • For two-post installations (ACX5096 only):

        • One pair of mounting brackets (not provided).

        • Sixteen screens for attaching the brackets to the chassis (not provided).

        • Four screws to secure the mounting brackets and chassis to the post (not provided).

    • Appropriate screwdriver for the mounting screws (not provided).

    • Two power cords with plugs appropriate to your geographical location (provided).

    • RJ-45 cable and RJ-45 to DB-9 serial port adapter (provided).

    • Management host, such as a PC laptop, with a serial port (not provided).

Optional equipment: Grounding cable kit with bracket, lug, and three nuts with integrated washers.

Warning:

The 1 U ACX5048 must be supported at all four corners. Mounting the chassis using only the front brackets will damage the chassis and can result in serious bodily injury.

CAUTION:

All ACX5000 routers require two people for installation, one person to lift the router into place, and another person to attach the router to the rack. If you are installing the ACX5000 routers above 60 in. (152.4 cm) from the floor, you can remove the power supplies and fan modules to minimize the weight before attempting to install the router.

CAUTION:

If you are mounting multiple routers on a rack, mount the router in the lowest position of the rack first. Proceed to mount the rest of the routers from the bottom to the top of the rack to minimize the risk of the rack toppling.

Four Post Procedure

To mount the router on four posts in a rack using the provided mounting kit:

  1. Attach the ESD grounding strap to your bare wrist and to a site ESD point.
  2. Decide whether the Field Replaceable Unit (FRU) end of the router or the port end is to be placed at the front of the rack. Position the router in such a manner that the AIR OUT labels on components are next to the hot aisle.
  3. Align the holes in the mounting rail with the holes on the side of the chassis. See Figure 1 for the alignment for the ACX5048, and Figure 2 for the ACX5096 router.

  9. Ensure that the router chassis is level by verifying that all the screws on the front of the rack are aligned with the screws at the back of the rack.

Two Post Procedure

You can center mount a ACX5096 on two posts of a 19-in. rack or cabinet by using the short mounting brackets provided with the router. Other product SKUs of the ACX5000 are not recommended for two post installation.

To mount the router on two posts in a rack using the provided mounting kit:

  1. Attach the ESD grounding strap to your bare wrist and to a site ESD point.
  2. Decide whether the Field Replaceable Unit (FRU) end of the router or the port end is to be placed at the front of the rack. Position the router in such a manner that the AIR OUT labels on components are next to the hot aisle.
  3. Align the tenmounting holes on the short mounting bracket with one of the three sets of corresponding holes along the side of the router chassis . See Figure 6.
