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.
Warning
Do not install the power supplies with the chassis cover off.
Note
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.
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
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.
Note
Wiring the DC Input Power Source
To reduce risk of electric shock, when installing or replacing the unit, the ground connection must always be
made first and disconnected last.
Warning
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.
It is not required to place the power switch in the Standby position if you want to hot-swap a single
power supply.
Note
Step 3 Remove the plastic cover from the terminal block.
Before you continue to install the terminal block ground wires, stop and perform Step 4.
Caution
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.

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.
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.
Note
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.
Removing an EPA while traffic is flowing through the ports may cause system disruption.
Caution
a) At the router# prompt, enter hw-module subslot 0/2 stop and press Enter.
b) At the router# prompt, enter end and press Enter.
