Install and connect

This section describes the installation procedure for C8475-G2 and C8455-G2 in an equipment rack.

  • Two-post rack, either 19 inch or 23 inch. Inner clearance (the width between the inner sides of the two posts or rails) must be at least 19 inches (48.26 cm) or 23 inches (58.42 cm). Airflow through the chassis is from front to back (I/O-side to PSU-side).

  • (Only supported on C8475-G2) Four-post, 19-inch equipment rack. Inner clearance (the width between the inner sidesof the two posts or rails) must be at least 19 inches (48.26 cm). Airflow through the chassis is from front to back.

Before you begin

Before installing and connecting a Cisco 8400 Series Secure Router, read the safety warnings and gather the tools and equipment. See the Required Tools and Equipment for Installation and Maintenance section, for more information about the required tools and equipment,

CLI console access

Use the USB or RJ-45 console port on the router to access the Cisco Internet Operating System (IOS-XE) and IOS XE SD-WAN command line interface (CLI) on the router and perform configuration tasks. A terminal emulation program is required to establish communication between the router and a PC. See the Connect to a Console Terminal or Modem section in this document for instructions.


Note
A Microsoft Windows USB driver must be installed before you establish physical connectivity between the router and the PC.

Install the routers

If you need to install Field-Replaceable Units (FRUs), you can install them either before or after you install the device. Ideally, you install the modules when you have access to the I/O side of the device. Internal modules (memory cards and fan trays) should be installed before rack-mounting.

The Cisco 8400 Series Secure Routers are designed to be rack-mounted.


Warning

Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord that is in the chassis. Statement 1


Caution

To prevent damage to the chassis, do not attempt to lift or tilt the chassis by holding it by the plastic panel on the front. Always hold the chassis by the sides of the metal body.

Mount the chassis on a rack


Warning

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.


Warning

To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 40C degrees on a continuous basis.

The Cisco 8400 Series Secure Routers can be installed in a 19-inch (48.26-cm) EIA or a 23-inch (58.42-cm) Southwestern Bell Corporation (SBC) racks. The Cisco 8400 Series Secure Routers can also be mounted in a 600-mm ETSI rack. Use the standard brackets shipped with the router for mounting the chassis in a 19-inch EIA rack; you can order optional larger brackets for mounting the chassis in a 23-inch SBC rack.

You can mount the devices in the following ways:

  • PS Mounting—Brackets are attached at the PS side of the chassis with the the PSUs facing forward.

  • I/O Mounting—Brackets are attached at the I/O side of the chassis with the I/O side facing forward.

  • Mid-Mounting —Brackets can be recessed or rotated to support multiple mounting-depth options.

Attach the rack-mounting brackets


Caution

Do not over-torque the screws. The recommended torque is 15 to 18 inch-lbs (1.7 to 2.0 N-m).


Caution

Your chassis installation must allow unrestricted airflow for chassis cooling.

Attach the mounting brackets to the chassis as shown in the below figure using the screws provided. Use a #2 Philips screwdriver.

To attach the rack-mounting brackets to the Cisco 8400 Series Secure Routers , perform these steps:

Step1. Select the depth location for the router in the equipment rack.

Step2. Align the rack mount bracket with the mounting holes in the side of the router.

Step3. Insert the #6-32 FHM screws. Use only the screws that are provided in the rack mount bracket kit.

Step4. Tighten the screws to a torque value of 15 to 18 inch-lb. (1.7 to 2.0 N-m).

The C8455-G2 is a shorter depth chassis and therefore has fewer options. The mid-mount depth options are shown below in isometric views.

Mount the chassis in a rack

After you attach the rack-mount brackets to the chassis, use screws to install the chassis in the rack.


Tip

For both the 19-inch EIA brackets and the 23-inch brackets, start the lower pair of screws first, and rest the brackets on the lower screws while you insert the upper pair of screws.


Tip

The screw slots in the brackets are spaced to line up with every second pair of screw holes in the rack. When the correct screw holes are used, the small threaded holes in the brackets line up with unused screw holes in the rack. If the small holes do not line up with the rack holes, you must raise or lower the brackets to the next rack hole.
