Unpacking and Mounting ACX5448, ACX5448-D, and ACX5448-M

Unpack an ACX5400 Router

The ACX5400 router chassis is a rigid sheet-metal structure that houses the hardware components. We ship the ACX5400 router in a cardboard carton, secured with foam packing material. The carton also contains an accessory box and quick start instructions.

CAUTION:

ACX5400 routers are maximally protected inside the shipping carton. Do not unpack the router until you are ready to begin installation.

To unpack an ACX5400 router:

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.
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 against the inventory included in the box. Table 1 lists the inventory of components that we supply with an ACX5400 router.
Pull out the packing material holding the router in place.
Verify the chassis components received:
- Two power supply modules (PSMs)
- Six fan modules
Save the shipping carton and packing materials in case you need to move or ship the router later.

Mount an ACX5400 Router in a Rack or Cabinet

You can mount an ACX5400 router in a four-post 19-in. rack or cabinet using the mounting kit provided with the device.

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.

Space the front and rear rack rails between 23.25 in. (59 cm) and 30.6 in. (77.7 cm) front-to-back.

Before You Begin Rack Installation

Before you begin mounting an ACX5400 router in the rack or cabinet:

Ensure that you understand how to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.
Verify that the site meets the requirements described in Site Preparation Checklist for ACX5448, ACX5448-D, and ACX5448-M Routers.
Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the building structure.
Read General Site Guidelines, with particular attention to Chassis and Component Lifting Guidelines.
Remove the router from the shipping carton. See Unpack an ACX5400 Router.
Ensure that you have the following parts and tools available to mount the router in a rack:
Note:
You can mount the ACX5400 router in a four-post rack or cabinet. We include the mounting blades, rails, and the respective screws for the four-post installation with the ACX5400 chassis in the shipping carton.
- ESD grounding strap (not provided).
- Blades, rails, or brackets (provided).
- 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).
- Twelve screws to secure the mounting rails to the chassis (provided).
- Eight screws to secure the chassis and mounting installation blades to the rack (not provided).
- Appropriate screwdriver for the mounting screws (not provided).
- Two power cords with plugs appropriate for 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 two screws with integrated washers.

Warning:

You must ensure rack support on all four corners of the 1 U ACX5400 router. Mounting the chassis using only the front brackets will damage the chassis and can result in serious bodily injury.

CAUTION:

The router requires 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 routers above 60 in. (152.4 cm) from the floor, you can remove the PSMs 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.

Install the ACX5400 Router in the Rack

To install the router in a four-post rack or cabinet:

Position the router in front of the rack or cabinet.
Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to the ESD point on the chassis.
Align the holes in the front-mounting rails with the holes on the side of the chassis (see Figure 1 for ACX5448, Figure 2 for ACX5448-D, and Figure 3 for ACX5448-M).
Figure 1: Install the Mounting Rails on an ACX5448 Router

Figure 2: Install the Mounting Rails on an ACX5448-D Router

Figure 3: Install the Mounting Rails on an ACX5448-M Router
Using a Phillips (+) number 2 screwdriver, secure the mounting rails to the chassis using the mounting screws.
With one person on each side, hold on to the bottom of the chassis and carefully lift it so that the mounting rails contact the rack rails.
Carefully slide the chassis with the rails attached on to the rack rails (see Figure 4 for the ACX5448 router, Figure 5 for the ACX5448-D router, and Figure 6 for the ACX5448-M router).

Figure 5: Install the ACX5448-D Router in a Four-Post Rack

Figure 6: Install the ACX5448-M Router in a Four-Post Rack
Install mounting screws into each of the front-mounting bracket holes aligned with the rack, starting from the bottom, and secure them tightly. Figure 7, Figure 8, and Figure 9 show the router fully secured to the front rails of the four-post rack.

Figure 9: ACX5448-M Router Secured by Front-Mounting Brackets
On the rear of the chassis, slide the rear-mounting blades on either side of the chassis until the rear-mounting brackets at the end of the blades contact the rack rails (see Figure 10 for the ACX5448 router, Figure 11 for the ACX5448-D router, and Figure 12 for the ACX5448-M router).
The rear-mounting blades on each side of the chassis are movable. You can adjust the length of the blades according to the depth of the rack.

Figure 11: Install the Mounting Blades on an ACX5448-D Router

Figure 12: Install the Rear-Mounting Blades on an ACX5448-M Router
Install mounting screws into each of the rear-mounting bracket holes aligned with the rack, starting from the bottom, and secure them tightly.
Visually inspect the alignment of the chassis. If you’ve installed the chassis properly in the rack, all the mounting screws on one side of the rack are aligned with the mounting screws on the opposite side, and the router is level. Figure 13, Figure 14, and Figure 15 show the router fully secured and installed in a four-post rack.
