Installing DC Input Power Supplies


Warning

Before performing any of the following procedures, ensure that power is removed from the DC circuit.


Warning

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.


Note

Do not install the power supplies with the chassis cover off.

This section describes how to install the DC power supply input power leads to the DC input power supply. Before you begin, read these important notices:

  • The color coding of the DC input power supply leads depends on the color coding of the DC power source at your site. Ensure that the lead color coding you choose for the DC input power supply matches the lead color coding used at the DC power source and verify that the power source is connected to the negative (–) terminal and to the positive (+) terminal on the power supply.

  • Ensure that the chassis ground is connected on the chassis before you begin installing the DC power supply. Follow the steps provided in the "Chassis Ground Connection" section.

  • For DC input power cables, the wire gauge is based on the National Electrical Code (NEC) and local codes for 26 amp service at nominal DC input voltage (–40/–72 VDC). One pair of cable leads, source DC (–) and source DC return (+), are required for each power distribution unit (PDU). These cables are available from any commercial cable vendor. All DC input power cables for the chassis should be 10 gauge wire and cable lengths should match within 10 percent of deviation.

Each DC input power cable is terminated at the PDU by a cable lug, as shown in the following figure.


Note

DC input power cables must be connected to the PDU terminal studs in the proper positive (+) and negative (–) polarity. In some cases, the DC cable leads are labeled, which is a relatively safe indication of the polarity. However, you must verify the polarity by measuring the voltage between the DC cable leads. When making the measurement, the positive (+) lead and the negative (–) lead must always match the (+) and (–) labels on the power distribution unit.

Figure 5. DC Input Power Cable Lug



Note

To avoid hazardous conditions, all components in the area where DC input power is accessible must be properly insulated. Therefore, before installing the DC cable lugs, be sure to insulate the lugs according to the manufacturer's instructions.

Wiring the DC Input Power Source


Warning

To reduce risk of electric shock, when installing or replacing the unit, the ground connection must always be made first and disconnected last.

Procedure

Step 1

Turn off the circuit breaker from the power source.

Step 2

Ensure that the chassis power switch is in the Standby position.

Note 

It is not required to place the power switch in the Standby position if you want to hot-swap a single power supply.

Step 3

Remove the plastic cover from the terminal block.

Caution 

Before you continue to install the terminal block ground wires, stop and perform Step 4.

Step 4

To prevent any contact with metal lead on the ground wire and the plastic cover, you must wrap the positive and negative lead cables with sleeving. Insulate the lug with shrink sleeving for each lead wire if using non-insulated crimp terminals. Sleeving is not required for insulated terminals.

Figure 6. DC Power Supply Terminal Block Ground Cable Lugs


Note 

This illustration shows the DC power supply for the Cisco ASR 1002-HX Router. The airflow for the Cisco ASR 1002-HX Router is reverse of what is shown in this illustration.

Step 5

For easier cable-management, insert the negative lead cable first. Replace the ground lug with cable in the following order:

  1. Wire terminal

  2. Screw with captive washer

Step 6

Tighten the M3 Screw with captive washer to recommended torque of 5 in-lbs for the positive stud and wire.

Note 

Secure the wires coming in from the terminal block so that they cannot be disturbed by casual contact.

Step 7

Replace the terminal block plastic cover. The plastic cover is slotted and keyed to fit correctly over the terminal block.

Step 8

Turn on the circuit breaker at the power source.

Step 9

If you have changed the chassis power switch to the Standby position in step 2, turn the power switch to the On position.

Removing and Replacing an EPA

The online insertion and removal (OIR) feature allows you to install and replace an Ethernet port adapter (EPA) while the router is operating. You do not have to shut down the system’s power, although you should not run traffic through the EPA while it is being removed. OIR is a method that is seamless to end users on the network, maintains all routing information, and preserves sessions.


Note

As you disengage the EPA from the router, OIR shuts down all the active interfaces in the EPA.

Note

For detailed information about EPA software commands, such as preparing for OIR of EPAs, and activating and deactivating configuration examples, see the Cisco ASR 1000 Series Modular Interface Processor Installation Guide.

We suggest you have the following tools and parts readily available for installing an EPA:

  • Number 2 Phillips or a 3/16-inch flat-blade screwdriver

  • EPA or blank filler plate (EPA-BLANK=)

  • Any SFP modules that you have to install (and have not already installed)

  • Cables

  • Your own ESD-prevention equipment or the disposable grounding wrist strap included with all upgrade kits, field-replaceable units (FRUs), and spares

  • Antistatic mat or surface, or static shielding bag

If you need additional equipment, contact a service representative for ordering information.

Electrostatic Discharge Prevention

Electrostatic discharge (ESD) damages equipment and impairs electrical circuitry. ESD occurs when printed circuit boards are improperly handled and results in complete or intermittent failures.

Each EPA circuit board is mounted to a metal carrier and is sensitive to ESD damage. an EPA consists of a printed circuit board that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and a handle are integral components of the carrier.

When the subslot is not in use, an EPA blank filler plate must fill the empty subslot to allow the router to conform to EMI emission requirements and to allow proper airflow across the installed modules. If you plan to install the EPA in the subslot that is not in use, you must first remove the EPA blank filler plate.

Figure 17. Handling an EPA


Although the metal carrier helps to protect the EPA from ESD, wear a preventive antistatic strap whenever you handle the EPA. Ensure that the strap makes good skin contact and connect the strap’s clip to an unpainted chassis surface to safely channel unwanted ESD voltages to ground.

If no wrist strap is available, ground yourself by touching the metal part of the chassis.

The following are the guidelines for preventing ESD damage:

  • Always use an ESD wrist strap or ankle strap when installing or replacing an EPA. Ensure that the ESD strap makes contact with your skin.

  • Handle the EPA by its metal carrier edges and handles; avoid touching the printed circuit board or any connector pins.

  • When removing the EPA, place it on an antistatic surface with the printed circuit board components facing upward, or in a static shielding bag.

Removing an EPA

Procedure

Step 1

Attach an ESD wrist strap between you and an unpainted chassis surface.

Step 2

Stop the EPA so that there is no traffic running through the EPA when it is removed.

Caution 

Removing an EPA while traffic is flowing through the ports may cause system disruption.

  1. At the router# prompt, enter hw-module subslot 0/2 stop and press Enter.

  2. At the router# prompt, enter end and press Enter.

Step 3
