Install the Cisco NCS 1020 Chassis

This chapter contains procedures to install the Cisco NCS 1020 chassis.

Rack Compatibility

The Cisco NCS 1020 chassis can be installed in a standard EIA (19"), ANSI (23"), or ETSI rack.

  • The rack can be two post type or four post type rack.

  • The 19" and 23" racks must be compliant with "EIA Universal" holes.

  • The ETSI Rack must be compliant with "ETSI Universal" holes.

Attach the Mounting Brackets to the Chassis

Use this procedure to attach the mounting brackets to the Cisco NCS 1020 chassis.

Before you begin

Required tools and equipment:

  • NCS1020-19-KIT= accessory kit

  • Torx head screwdriver (Cisco supplied)

Procedure

Step 1

Identify the left and right brackets.

Step 2

Place the wider side of the mounting bracket flush against the chassis markings on the sides.

Step 3

Align the mounting bracket screw holes against the chassis screw holes.

Step 4

Insert the M4 flat head screws available in the accessory kit (NCS1020-19-KIT=) and tighten them to a torque value of 1.5 N-m (13.3 lbs-in).

Step 5

Repeat the preceding steps to mount the bracket on the opposite side.

Use this procedure to mount the Cisco NCS 1020 chassis on an EIA/ANSI/ETSI rack.


Note

The mounting brackets and adapters fit only in the front posts of the four-post rack. Therefore, you can use the mounting brackets and adapters for both two-post and four-post racks.


Warning

Rack Mount Instructions

The following or similar rack-mount instructions are included with the installation instructions:

  • Elevated Operating Ambient—If installed in a closed or multirack assembly, the operating temperature of the rack environment may be greater than room temperature. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified.

  • Reduced Air Flow—Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.

  • Mechanical Loading—Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.

  • Circuit Overloading—Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

  • Reliable Earthing—Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (for example, use of power strips).

Before you begin

Ensure that the rack is compatible. See Rack Compatibility.

Attach the Mounting Brackets to the Chassis

Procedure

Step 1

Attach the rack adapters to the chassis. Perform one of the following steps.

  • For the 19" rack, the chassis directly fits the rack.

  • For the 21" rack, use the 19 to ETSI adapter from the accessory kit (NCS1020-ETSI-KIT=). For the 23" rack, use the 19" to 23" adapter from the accessory kit (NCS1020-23-KIT=). To attach the 19" to ETSI or 19" to 23" adapter:

    1. Identify the left side and right side adapters.

    2. Place the adapters behind the narrower side of the mounting brackets.

    3. Align the adapter screw holes against the mounting bracket screw holes.

    4. Insert the adapter screws from the front on either side of the chassis.

    5. Tighten the adapter screws to a torque value of 4.65 N-m (41 lbs-in).

Step 2

Mount the NCS 1020 chassis onto the rack. Perform the following steps:

  1. Lift the chassis to the needed position in the rack.

    The fully loaded chassis requires two people to lift. Alternatively, you can use a mechanical lift to position the chassis in the rack.

  2. Align the mounting bracket screw holes against the rack screw holes.

    For ETSI and 23" racks, align the adapter screw holes against the rack screw holes.

  4. Using a screwdriver, tighten the 12–24 pan head screws to a torque value of 1.5 N-m (13.3 lbs-in).

General Power and Grounding Requirements

General power and grounding requirements are:

  • Installation of the routing system must follow national and local electrical codes:

    • In the United States: United States National Fire Protection Association (NFPA) 70 and United States National Electrical Code (NEC).

    • In Canada: Canadian Electrical Code, part I, CSA C22.1.

    • In other countries: International Electrotechnical Commission (IEC) 60364, parts 1 through 7.

  • Two separate and independent AC or DC power sources are needed to provide 2N redundancy for system power. Each power source requires its own circuit breaker.

  • Each power source must provide clean power to the site. If necessary, install a power conditioner.

  • The site must provide short-circuit (over-current) protection for devices.

  • Proper grounding is required at the site to ensure that equipment is not damaged by lightning and power surges.


    Note

    Ground lug connection is mandatory for the AC chassis version too.

  • Site power planning must include the power requirements for any external terminals and test equipment you will use with your system.


Note
Be sure to review the safety warnings in the Cisco Network Convergence System Regulatory Compliance and Safety Information for the Cisco Network Convergence System 1020 before attempting to install the chassis.

Ground NCS 1020

This procedure provides the grounding details for the NCS 1020 chassis. In the installation of the chassis, the ground lug should be connected first.

There is one grounding point at the rear side of the NCS 1020 chassis. The following warning is affixed as a label on the chassis.


Warning

High leakage current, earth connection essential before connecting supply.


Caution

When terminating the frame ground, do not use soldering lug connectors, screwless (push-in) connectors, quick connect connectors, or other friction-fit connectors.

Procedure

Step 1

Verify that the office ground cable is connected to the top of the rack and the office ground, according to local site practice.

Step 2

Remove any paint and other nonconductive coatings from the surfaces between the shelf ground and bay frame ground point. Clean the mating surfaces and apply the appropriate antioxidant compound to the bare conductors.

Step 3

Attach one end of the shelf ground cable (#6 AWG cable) to the ground point using the dual-hole lug connector.

Step 5

Attach the other end of the shelf ground cable to the bay frame using a dual-hole lug connector according to the equipment rack frame specifications.
