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 bottom 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 nine 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)

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

craft panel

The craft panel can install, configure, monitor, and troubleshoot the Cisco NCS 4009 chassis applications at the node and at the network level. The craft panel is located on top of the ECU.

fan tray

One fan tray is inserted into the front of the chassis behind the craft panel. The fan tray cools the card rack. The fan tray contains six axial fans. The fans pull cooling air through the chassis from front to rear.

air filter

One air filter is located above the slots of the fabric cards.

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.

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 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.
