Chassis Components

This table lists the main components of the Cisco NCS 4016 chassis.

Table 1. Main Components of the Cisco NCS 4016 Chassis

Component

Description

route processor cards (RPs)

Two RP cards (RP0/RP1) are inserted into the front of the chassis. These cards provide the intelligence of the system by functioning as the system controller and providing route processing and chassis management. The RP cards also monitor system alarms and control the system fans. The LEDs on the front panel indicate active alarm conditions.

fabric cards (FCs)

Four FCs are inserted into the front of the chassis. The FCs provide the switch fabric for the routing system and performs the cross-connect function of the routing system, connecting every LC to each other. The switch fabric receives ingress user data from one LC slot and performs the switching necessary to route the data to the appropriate egress LC slot.

line cards (LCs)

As many as sixteen LCs can be inserted into the front of the chassis. These cards provide the physical interfaces and optical connections for the user data.

external connection unit (ECU/ECU2)

The ECU/ECU2 provides all shelf electrical I/O connectivity to the active and standby route-processor cards. The ECU/ECU2 is located behind the craft panel.

ECU2 has four timing expansion (TE) ports on front panel. Two are primary ports and the other two are meant for redundancy and fail over. These TE ports are used for connecting NCS 4000 chassis in the multi chassis configuration.

craft panel

The craft panel can install, configure, monitor, and troubleshoot the Cisco NCS 4016 chassis applications at the node and at the network level. The craft panel is located on top of the ECU/ECU2.

fan trays

Two fan trays are inserted into the front of the chassis at the top and bottom. The top fan tray (behind the craft panel) cools the top card rack and the bottom fan tray covers the bottom card rack. Each fan tray contains six axial fans. The fans pull cooling air through the chassis from the front to rear.

air filter

Two independent air filters are located in the middle of the chassis behind the plastic inlet grill. One is dedicated to the top card rack and the other to the bottom card rack.

We recommend that you change the air filter every three months. The filter is sold in packs of 5 (Cisco PID NCS4K-FTF=).

power trays

Two power trays provide redundant power to the chassis. Both AC and DC power trays are available. Each power tray holds up to four AC or DC power modules. A power tray is a field serviceable unit (FSU). A mixture of AC and DC power is not supported in the chassis.

Note

 
You must power off the chassis before replacing a power tray.

fiber management trays

Two fiber management trays are located on the front of the chassis. One is above the top card rack and the other is below the bottom card rack.

Chassis Slot Numbers

This section identifies the location and slot numbers for the cards and power modules that plug into the chassis.

Note
Cards in the top and bottom card cages are not inserted in the same direction. If you consider , the above figure, as a reference, cards in the bottom card cage are inserted upside down.

The chassis has the following card slots:

  • Sixteen LC slots:
    • Eight in the top card cage (LC0 to LC7)
    • Eight in the bottom card cage (LC8 to LC15)
  • Two RP slots:
    • One in the top card cage (RP0)
    • One in the bottom card cage (RP1)
  • Four FC slots:
    • Two in the top card cage (FC0, FC1)
    • Two in the bottom card cage (FC2, FC3)
  • Two fan trays for redundancy at the top and the bottom of the chassis
  • One external connection unit (ECU/ECU2) located above the top fan tray behind the craft panel
  • Two fiber management areas at the top and the bottom of the chassis

The following guidelines are for your safety and to protect equipment. The guidelines do not include all hazards. Be alert.

  • Never attempt to lift an object that might be too heavy for you to lift by yourself.

  • Keep the work area clear and dust-free during and after installation. Do not allow dirt or debris to enter into any laser-based components.

  • Keep tools and chassis components away from walk areas.

  • Do not wear loose clothing, jewelry, and other items that could get caught in the chassis while working with the chassis and its components.

  • Use Cisco equipment in accordance with its specifications and product-usage instructions.

  • Do not work alone if potentially hazardous conditions exist.

  • Make sure that your installation follows national and local electrical codes: in the United States, National Fire Protection Association (NFPA) 70, United States National Electrical Code; in Canada, Canadian Electrical Code, part I, CSA C22.1; in other countries, International Electrotechnical Commission (IEC) 60364, part 1 through part 7.

  • Connect only a DC power source that follows the safety extra-low voltage (SELV) requirements in UL/CSA/IEC/EN 60950-1 and AS/NZS 60590 to the DC input power system.

  • Make sure that you have a readily accessible two-poled disconnect device incorporated in the fixed configuration wiring of a DC input power system.

  • Make sure that you provide short-circuit (overcurrent) protection as part of the building installation.

Preventing Electrostatic Discharge

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. We recommend use of an ESD-preventive wrist strap whenever you handle network equipment or one of its components.

Following are guidelines for preventing ESD damage:

  • Always use an ESD-preventive wrist or ankle strap, and ensure that it makes good skin contact. Connect the equipment end of the connection cord to an ESD jack (ESD Jacks—Top of Chassis and ESD Jacks—Bottom of Chassis ) or a bare metal surface on the chassis (ensure the chassis is grounded).
  • Handle a card by its ejector levers, when applicable, or its metal carrier only; avoid touching the board or connector pins.
  • Place a removed card board side up on an antistatic surface or in a static-shielding bag. If you plan to return the component to the factory, immediately place it in a static-shielding bag.
  • Avoid contact between a card and clothing. The wrist strap protects the board from only ESD voltage on the body; ESD voltage on clothing can still cause damage.
