Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030.

Overview

The Cisco uBR10012 router is shipped with two AC power entry modules (AC PEMs) that provide power supply to the system. One AC PEM module is sufficient to provide power for a fully configured chassis. However, if one AC PEM module fails, the other AC PEM module automatically begins providing power to the entire chassis, without impacting the system operation.

The AC PEM modules use a standard 200-240 VAC (50 or 60 Hz) input power obtained through power receptacles on the front panel of each PEM. The two AC PEMs convert the AC power to provide filtered, redundant, and load shared DC power to the Cisco uBR10012 chassis. The AC PEM modules can be identified by their product part numbers.

The AC PEM modules supported on the Cisco uBR10012 chassis are:

AC PEM Module (UBR10-PWR-AC=)

AC PEM Module (UBR10-PWR-AC-PLUS=)

Table 1 summarizes the specifications of the AC PEM modules:

This document includes procedures for installing, replacing, and removing the 3300 W AC power entry module (UBR10-PWR-AC-PLUS=). For information on migrating from the 2400 W AC PEM to the 3300 W AC PEM, see "Migrating from the 2400 W AC PEM to the 3300 W AC PEM" section.

For information on installing, replacing, and removing the 2400 W AC PEM, see AC Power Entry Module for the Cisco uBR10012 Universal Broadband Router.


Caution The Cisco uBR10012 router supports using either the AC PEM modules or the DC PEM modules, but it does not support mixing AC and DC PEMs. Both PEMs must be either AC PEMs or DC PEMs.


Caution The 3300 W AC PEMs cannot be used with a 100-120 VAC input power source.


Tip For fully redundant power protection, use either an uninterruptible power supply (UPS) or a separate AC-input power source for each 3300 W AC PEM.


Physical Description

The 3300 W AC PEM module provides a power output of 3300 W with dual AC-input power connections. This AC PEM module provides:

LEDs

Four LEDs (V1 POWER, V2 POWER, POWER, and FAULT) indicate the status of the AC PEM module. In addition, there is a PRODUCT ID LED/switch on the front panel of the AC PEM module.


Tip Use a small object, such as a paper clip, to press the PRODUCT ID LED/switch inside the cavity on the front panel of the AC PEM module.


Table 2 describes the LEDs on the 3300 W AC PEM.

Table 2 AC PEM LEDs and Their Functions

LED
Color
Description

VI POWER

Green

Indicates that the PEM is receiving power from the AC power source. These LEDs only indicate that an input voltage is present on the PEMs and not that the PEM is powered on.

Note This LED may illuminate even if the voltage applied is not in the proper range to power on the PEM.

V2 POWER

Green

Indicates that the PEM is receiving power from the AC power source. These LEDs only indicate that an input voltage is present on the PEMs and not that the PEM is powered on.

Note This LED may illuminate even if the voltage applied is not in the proper range to power on the PEM.

POWER

Green

Indicates that the power at the output is within the required voltage, and the PEM is providing power to the Cisco uBR10012 chassis.

FAULT

Yellow

Indicates that the AC-input power is being received by the PEM, but that the PEM is not supplying power to the chassis, typically because the power enable switch of the AC PEM is set to the Standby (0) position.

If the power switch is in the ENABLE (|) position, and the FAULT LED is illuminated, the PEM is not operating correctly.

PRODUCT ID LED/switch

Green

When you press the PRODUCT ID LED/switch it illuminates (green) and the Cisco IOS software identifies the PEM module as UBR10-PWR-AC-PLUS only if you are running a supported Cisco IOS Release on the chassis. Otherwise, the software reports the default UBR10-PWR-AC product part number and the show environment command randomly displays the PEM type as DC instead of AC.


Table 3 lists the default activation status of the PRODUCT ID LED/switch when it is shipped.

PRODUCT ID LED/Switch Default Activation Status


Note If you are installing the AC PEM module (spare) in an existing Cisco uBR10012 router chassis, ensure that the Cisco IOS Release running on the chassis supports the PRODUCT ID LED/switch feature before installing the module.



Note Even if you are using a supported Cisco IOS Release, the software may not identify the PEM module as UBR10-PWR-AC-PLUS. If this occurs, ensure that the PRODUCT ID LED/switch is illuminated and then either reload the software, or physically remove the AC PEM module for at least 1 minute and then reinsert it.


Air Flow

The 3300 W AC PEM works together with the fan assembly module to ensure that the Cisco uBR10012 chassis is properly cooled during normal operation. Figure 3 shows the airflow through the Cisco uBR10012 chassis when dual AC PEMs are installed.

Figure 3 Airflow Through the Cisco uBR10012 Chassis with Dual 3300 W AC PEMs


Note Figure 3 shows the Cisco uBR10012 chassis without the front cover (U-CHAS-COVER-PLUS=) installed. The front cover should be installed during normal operation so that the air filter in the cover can filter the incoming air before it enters the chassis.


Power Supply Cables

The 3300 W AC PEM requires different power supply cables, depending on the country of operation.


Note The two AC power cables must be connected and powered on for each AC PEM to function properly. Ensure that you exercise caution when the AC power cables are attached to the facility power source, and the facility power is turned on. The AC PEM internal fans start working and are audible as soon as the AC power cables are installed and AC power is supplied to the AC PEMs, although the AC power enable switch is in the Standby (0) position.



Note The U-CHAS-COVER-PLUS= front cover must be used with the Cisco uBR10012 chassis for proper routing of the AC cables from the 3300 W AC PEMs through the chassis to the facility power source.

(To see translations of the warnings that appear in this publication, refer to the appendix "Translated Safety Warnings" in the installation guide that accompanied this device.)

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room where you are working.

Disconnect all power and external cables before moving a chassis.

Do not work alone when potentially hazardous conditions exist.

Never assume that power has been disconnected from a circuit; always check.

Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which occurs when electronic cards or components are improperly handled, can result in complete or intermittent failures.

The 3300 W AC PEMs contain a printed circuit card that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the cards from ESD, use an antistatic strap each time you handle the modules.

Guidelines for preventing ESD damage:

Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. Before removing a card from the chassis, connect the equipment end of the strap to a bare metal, unpainted surface on the chassis, or rack-mount.

Handle components by the carrier edges only; avoid touching the card components or any connector pins.

When removing a module, place it on an antistatic surface or in a static-shielding bag. If the module is to be returned to the factory, immediately place it in a static-shielding bag.

Avoid contact between the modules and clothing. The wrist strap protects the card from ESD voltages on the body only; ESD voltages on clothing can still cause damage.


Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohm).

Step 6 Verify that the following LEDs are illuminated properly.

The V1 POWER and V2 POWER LEDs on each PEM are illuminated (green). In addition, the POWER LED on each PEM is illuminated (green) indicating that power is being received and is being delivered to the chassis.

If the FAULT LED illuminates (yellow), see the "Troubleshooting the 3300 W AC PEM" section.

If you are running a Cisco IOS Release that supports the PRODCUT ID LED/switch feature, verify that the PRODUCT ID LED/switch illuminates (green).


Note If you are running a Cisco IOS Release that does not support the PRODUCT ID LED feature, ensure that the PRODUCT ID LED/switch is not illuminated. For information on Cisco IOS Releases that support the PRODUCT ID LED/switch feature, see Cisco uBR10012 Router Release Notes for Cisco IOS Release 12.2(33)SCE.



Removing and Replacing a 3300 W AC PEM


Note If a 3300 W AC PEM fails, order and install a replacement 3300 W AC PEM as soon as possible. The product order number for a replacement 3300 W AC PEM is UBR10-PWR-AC-PLUS=. For proper airflow, cooling, and safety, do not remove the failed unit until the replacement unit is available for installation.


This section contains information on removing and replacing 3300 W AC PEM modules in the Cisco uBR10012 router chassis.


Tip The 3300 W AC PEM is operating correctly when its POWER LED is illuminated (green). When the FAULT LED is illuminated (yellow), the AC PEM is receiving AC-input power but is not providing power to the system. Verify that the AC PEM is fully inserted into the power bay and that its captive screws have been tightened. Then, set the AC power enable switch on the 3300 W AC PEM to the Standby (0) position, wait several seconds, and then switch it to the ENABLE position. If the FAULT LED does not go off and the POWER LED does not illuminate (green), replace the 3300 W AC PEM.


This section represents the following topics:

Replacing a Redundant 3300 W AC PEM

Replacing Both 3300 W AC PEMs

Replacing a Redundant 3300 W AC PEM

This procedure is needed when the FAULT LED is illuminated (yellow) and the troubleshooting steps in the "Troubleshooting the 3300 W AC PEM" section do not correct the problem.

Prerequisites

No prerequisites exist for this task.

Required Tools and Equipment

Replacement AC PEM module (UBR10-PWR-AC-PLUS=)

Flat-head screwdriver

Steps


Tip If you want to replace both 3300 W AC PEMs without shutting down the router, repeat this procedure for each AC PEM, one at a time. Do not use this procedure if both 3300 W AC PEMs have failed; instead, use the procedure in the "Replacing Both 3300 W AC PEMs" section.


To replace and install a redundant 3300 W AC PEM module:


Step 1 Remove the front cover by lifting it up slightly and then pulling it towards you.

Step 2 Turn off the 3300 W AC PEM you are replacing by positioning the AC power enable switch to the Standby (0) position (see Figure 9).

Figure 9 AC Power Switch in Standby Position


Caution Do not power off both 3300 W AC PEMs because it will cause the system to shut down and all data traffic to stop. Power off only the 3300 W module you are replacing.

Step 3 Unplug the AC-input power cables from the AC power receptacles on the front panel of the AC PEM. For safety, also unplug the other end of the power cables from the AC-input power source.


Tip For true redundant power protection, ensure that you are using separate AC-input power sources for each 3300 W AC PEM.


Step 4 Use a screwdriver to loosen the captive screws on the 3300 W AC PEM you are removing. Then pull the PEM from the chassis by using the handles on the faceplate (see Figure 10). Set the removed 3300 W AC PEM aside on an antistatic mat.

Figure 10 Removing the AC PEM

Step 5 Verify that the AC power enable switch on the replacement 3300 W AC PEM is in the Standby (0) position.

Step 6 Install the replacement 3300 W AC PEM in the power bay, see "Installing the AC Power Entry Modules" section.

Step 7 Plug the AC-input power cables into the AC power receptacles on the front panel of each AC PEM, see "Connecting the AC Power Cables on the AC Power Entry Modules" section.


Note The two AC power cables must be connected and powered on for the AC PEM to function.


Step 8 Plug the other end of the AC-input power cables into a 200-240 VAC power outlet, see "Powering On the AC Power Entry Module" section.


Replacing Both 3300 W AC PEMs


Note The illustrations for this procedure are identical to the illustrations in the "Replacing a Redundant 3300 W AC PEM" section and therefore not repeated.


Prerequisites

This procedure is needed only when you need to move the chassis or reinstall it in another location.

Required Tools and Equipment

AC PEM modules (UBR10-PWR-AC-PLUS=)

Flat-head screwdriver

Steps

To replace both the 3300 W AC PEM modules:


Step 1 Remove the front cover.

Step 2 Shut down the system using the following procedure:

a. Notify appropriate personnel that you plan to shut down the system and that the shutdown will result in total loss of service. Appropriate personnel includes the regional alarm or network monitoring center, central office personnel, and key customers.

b. Before you shut down the router, use the copy command to save any configuration changes to the NVRAM and, if you want, to a PCMCIA Flash memory card. For instructions about using the copy command, see the Cisco uBR10012 Universal Broadband Router Software Configuration Guide.

c. Set the AC power enable switch on each AC PEM to the Standby (0) position.

Step 3 Unplug the AC-input power cables from the power receptacles on the front panel of each 3300 W AC PEM. For safety, also unplug the other end of the power cables from each AC-input power source.

Step 4 Use the screwdriver to loosen the captive screws on each 3300 W AC PEM. Then pull each AC PEM from the chassis by using the handles on the faceplate. Set the two AC PEMs aside on an antistatic mat.

Step 5 Verify that the AC power enable switch on each replacement 3300 W AC PEM is in the Standby (0) position.

Step 6 Install the first replacement 3300 W AC PEM in the power bay, see "Installing the AC Power Entry Modules" section.

Step 7 Install the second replacement 3300 W AC PEM in the power bay, see "Installing the AC Power Entry Modules" section.


Caution Although one 3330 W AC PEM can supply sufficient power for a fully configured chassis, we recommend that you run the Cisco uBR10012 router with two 3300 W AC PEMs installed, because this provides redundant power support.

Step 8 Plug the AC-input power cables into the AC power receptacles on the front panel of each AC PEM, see "Connecting the AC Power Cables on the AC Power Entry Modules" section.


Note The two AC power cables must be connected and powered on for the AC PEM to function.


Step 9 Plug the other end of the AC-input power cables into a 200-240 VAC power outlet, see "Powering On the AC Power Entry Module" section. For a fully redundant operation, each 3300 W AC PEM should use separate power sources, or you should be using an uninterruptible power supply (UPS).


Migrating from the 2400 W AC PEM to the 3300 W AC PEM

This section describes the steps for a seamless migration from the 2400 W AC PEM modules to the 3300 W AC PEM modules.

Prerequisites

The 3300 W AC PEM module requires two AC power cables to be installed on each PEM module as against the single AC power cable for the 2400 W AC PEM module.

The routing of the AC power cables for the 3300 W AC PEM is different from the routing of the AC power cable for the 2400 W AC PEM. If you are using an existing AC power cable, the installation should be examined prior to migration for proper cable routing.

The U-CHAS-COVER-PLUS= front cover must be used with the Cisco uBR10012 chassis with the 3300 W AC PEMs.


Note You do not need to shut down the Cisco uBR10012 router to replace a 2400 W AC PEM module with a 3300 W AC PEM module. To avoid shutting down the Cisco uBR10012 router, you must replace one 2400 W AC PEM at a time; bring the 3300 W AC PEM module online, and then replace the other 2400 W AC PEM module.


Required Tools and Equipment

3300 W AC PEM module (UBR10-PWR-AC-PLUS=)

2400 W AC PEM module (UBR10-PWR-AC=)

Two AC power cables

Front cover (U-CHAS-COVER-PLUS=)

Flat-head screwdriver

Steps

To replace the 2400 W AC PEM with the 3300 W AC PEM module:


Step 1 Remove the front cover on the 2400 W AC PEM modules.

Step 2 Set the AC power switch to Standby (0) position on one of the 2400 W AC PEM (that is to be removed) modules (see Figure 11).

Figure 11

AC Power Switch UBR-10-PWR-AC=

Step 3 Unplug the AC-input power cable from the power plug on the front panel of 2400 W AC PEM module. For safety, also unplug the other end of the power cable from each AC-input power source.

Step 4 Use a screwdriver to loosen the captive screws on the 2400 W AC PEM that you are removing. Then pull the 2400 W AC PEM from the chassis by using the handles on the faceplate and set the 2400 W AC PEM aside on an antistatic mat.

Step 5 Verify that the POWER LED on the other 2400 W AC PEM module is illuminated (green) and does not blink.

Step 6 Position the 3300 W AC PEM in the power bay and slide it all the way in and ensure it makes a secure connection with the chassis backplane, see "Installing the AC Power Entry Modules" section.

Step 7 Plug the two AC-input power cables into the power receptacles on the front panel of the 3300 W AC PEM, see "Connecting the AC Power Cables on the AC Power Entry Modules" section.


Note The two AC power cables must be connected on the 3300 W AC PEM modules for proper functioning of the PEM module.


Step 8 Plug the other end of the AC-input power cables into a 200-240 VAC power outlet, see "Powering On the AC Power Entry Module" section.


Note Verify that the V1 POWER and V2 POWER LEDs illuminate (green) on the 3300 W AC PEM module.


Step 9 Turn the AC power enable switch on the 3300 W AC PEM module to the ENABLE (|) position.

The FAULT LED should go off and the POWER LED should illuminate (green).

Step 10 Verify if the POWER LED illuminates (green) within three seconds on the 3300 W AC PEM module. If the POWER LED on the 3300 W AC PEM remains green and does not blink, it indicates that the migration is successful and the 3300 W AC PEM is now enabled and is supplying power to the chassis.

Step 11 Repeat Step 1 to Step 10 to replace the second 2400 W AC PEM module with the 3300 W AC PEM module.

Step 12 Install the U-CHAS-COVER-PLUS= front cover on the 3300 W AC PEM modules.

Step 13 Route the power cable out through the right side, so that it fits through the notch on the right side of the front cover.


Troubleshooting the 3300 W AC PEM

Check the following to help isolate a problem with the 3300 W AC PEM:

The AC power cables are installed into the AC PEM receptacles and the facility power source is turned on. The AC power enable switch is set to the Standby (0) position.

Check if the AC PEM is receiving power.

The V1 POWER and V2 POWER LEDs should illuminate (green).

If these LEDs are not illuminated, check the external wiring and facility power source. If the fans are working and are audible, it indicates that the AC PEM is receiving power, so there could be a possibility that the LEDs are not working.

The FAULT LED should illuminate (yellow).

If this LED is not illuminated, there could be a possibility that the LED is not working, therefore the LED cannot indicate a valid fault on the PEM.

If the above LEDs do not illuminate but you are confident that PEM is receiving power, you can proceed to power on the PEM, see "Powering On the AC Power Entry Module" section. Ensure that the POWER LED is not illuminated (green). If this LED is illuminated, the AC PEM should be replaced. See the "Obtaining Documentation and Submitting a Service Request" section.

The AC PEM is powered on, and the V1 POWER and V2 POWER LEDs are illuminated (unless they may not be working, as above). The AC power enable switch on the AC PEM is set to the ENABLE (|) position.

The FAULT LED should stop illuminating. If it remains illuminated, the AC PEM should be replaced because this is a valid fault. See the "Obtaining Documentation and Submitting a Service Request" section.

The POWER LED should illuminate (green). If this LED does not illuminate, and the FAULT LED is not illuminated, there might be a possibility that the POWER LED is not working. You may need to verify if the PEM is providing valid power to the system by checking the AC PEM voltage and current using the Cisco IOS Release running on the router. Contact technical support for assistance, see the "Obtaining Documentation and Submitting a Service Request" section.

The FAULT LED is illuminated (yellow).

The FAULT LED illuminates when the PEM module detects an over-voltage or over-current condition, or when the PRE issues the command to shut down the PEM module (this could occur due to overheating). Ensure that none of these conditions exist in the system, and then try to switch the PEM module off and switch it on again.

If another PEM module exists in the system that powers up the chassis, and the FAULT LED is not illuminated on that module, then ensure that the PRE does not issue the command to shut down the PEM module.

If the problem persists, try another working unit. Else, see the "Obtaining Documentation and Submitting a Service Request" section.

The show environment command output displays a DC PEM module instead of AC PEM.

Upgrade to a supported Cisco IOS Release and then press the PRODUCT ID LED/switch.

Reload the software or physically remove the AC PEM module for at least 1 minute and then reinsert it.


Note The show environment command provides accurate information on the 3300 W AC PEM if the Cisco uBR10012 router is running a supported Cisco IOS Release. If using an earlier Cisco IOS release, the show environment command will not correctly identify the error messages of the 3300 W AC PEM.


If none of the above suggestions correct the problem, the 3300 W AC PEM could be faulty. Contact technical support for assistance, see "Obtaining Documentation and Submitting a Service Request" section.
