DC-Input Power Entry Module Overview

A Cisco 12016 GSR configured for source DC operation ships with four DC-input power entry modules (full redundant power) installed in the DC-input power shelf. (See Figure 1.)

Figure 1: Cisco 12016 GSR DC-Input Power Subsystem (Front View)

In the full redundant power configuration, modules A1 and B1 provide redundant power for chassis backplane load zone 1, which consists of the upper blower module and the upper card cage. Modules A2 and B2 provide redundant power for chassis backplane load zone 2, which consists of the switch fabric card cage, the lower card cage, and the lower blower module.

Caution A Cisco 12016 GSR configured for source DC operation must be operated with four DC-input power entry modules installed at all times for electromagnetic compatibility (EMC).

Note The DC-input power entry modules support online insertion and removal (OIR), so if your Cisco 12016 router is operating with four DC-input power entry modules, you can remove and replace one power entry module in each load zone (A1 or B1; A2 or B2) while the system remains powered up.

The DC-input power entry module is a modular unit that slides in and out of the power shelf and is secured by a captive screw and ejector lever on the power entry module faceplate. (See Figure 2.)

Figure 2: Cisco 12016 GSR DC-Input Power Entry Module Faceplate

The DC-input power entry module operates from a nominal source DC voltage of -48 to -60 VDC and requires a dedicated 60A service. It has the following faceplate features:

A handle to grip when removing and replacing the power entry module.
A circuit breaker switch.
An ejector latch and captive screw at the bottom right corner of the faceplate to seat and hold the power entry module in the power shelf.
An air intake opening in the front of the power entry module so the internal fan can pull cooler air into the front of the power entry module and force warm air out the back of the power shelf.
Three LEDs:
- PWR OK: When the power entry module is seated in the power shelf with the ejector lever in its closed position and the power shelf is connected to source DC, the green LED goes on immediately. The green LED remains on as long as the source DC voltage is within the nominal operational range of -48 to -54 VDC.
- FAULT: This yellow LED is on when a fault has been detected within the power entry module.
- TEMP: This yellow LED is on any time the power entry module is in an overtemperature condition.

Safety with Equipment

The following guidelines will help ensure your safety and protect the equipment. This list is not inclusive of all potentially hazardous situations, so be alert.

Always disconnect all power cords and interface cables before moving the system.
Never assume that power is disconnected from a circuit; always check.
Keep tools and assembly components away from walk areas.
Do not work alone if potentially hazardous conditions exist.
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.

Safety with Electricity

DC-input power entry modules support online insertion and removal OIR), so if your Cisco 12016 GSR is operating with four DC-input power entry modules, you can remove and replace one power entry module in each load zone (A1 or B1; A2 or B2) while the system remains powered up without presenting an electrical hazard or damage to the system.

Follow these basic guidelines when working with any electrical equipment:

Before beginning any procedures requiring access to the interior of the router, locate the emergency power-off switch for the room in which you are working.
Disconnect all power and external cables before installing or removing a router.
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.
Never install equipment that appears damaged.
Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.
If an electrical accident does occur, proceed as follows:
- Use caution; do not become a victim yourself. Disconnect power to the router.
- If possible, send another person to get medical aid; otherwise, assess the condition of the victim and then call for help.
- Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

In addition, observe the following guidelines when working with any equipment that is disconnected from a power source but still connected to telephone or network wiring:

Never install telephone wiring during a lightning storm.
Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Many router components can be damaged by static electricity. Some components can be damaged by voltages as low as 30V, while static voltages as high as 35,000V can be generated just by handling plastic or foam packing material, or by sliding assemblies across plastic and carpets. Not exercising the proper electrostatic discharge (ESD) precautions can result in intermittent or complete component failures. To minimize the potential for ESD damage, observe the following guidelines:

Always use an ESD-preventive antistatic wrist strap or ankle strap and ensure that it makes good skin contact.

Caution You should periodically check the resistance value of the ESD-preventive strap. The measurement should be between 1 and 10 megohms.

When removing or installing a component, make sure the equipment end of your antistatic strap leash is connected to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis. (See Figure 3.) Avoid contact between the component and your clothing. The ESD-preventive wrist strap only protects the component from ESD voltages on the body; ESD voltages on your clothing can still cause component damage.

Figure 3: Connecting an ESD-preventive Wrist Strap to the Cisco 12016 Chassis

Always place a card component-side up on an antistatic surface, in an antistatic card rack, or in a static shielding bag. If you are returning the item to the factory, immediately place it in a static shielding bag.
When installing a line card or GRP, use the ejector levers to seat the card connectors in the backplane, then tighten both captive screws on the card's faceplate. These screws prevent accidental removal, provide proper grounding for the router, and help to ensure that the card connector is seated in the backplane.
When removing line cards, clock and scheduler cards, switch fabric cards, or a GRP, use the ejector levers to unseat the card connector from the backplane. Pull the metal card carrier out slowly, placing one hand along the bottom of the carrier to guide it straight out of the slot.
Handle line cards, clock and scheduler cards, switch fabric cards, or a GRP by the metal card carrier edges only; avoid touching the board or any connector pins.

Tools and Parts Required

You need the following tools and parts to remove and replace a DC-input power entry module:

ESD-preventive wrist strap
3/16-inch flat-blade screwdriver
The replacement DC-input power entry module (Cisco product number PWR-GSR16-DC=).

Removing and Replacing a DC-Input Power Entry Module

This section provides three procedures:

Removing a DC-Input Power Entry Module from the Power Shelf

Figure 4 shows the steps in removing a DC-input power entry module from the power shelf.

Figure 4: Removing a DC-Input Power Entry Module

To remove a DC-input power entry module, use Figure 4 as a reference and follow these steps:

Step 1 Grasp the outside edges of the front cover over the upper blower module bay and power shelf and pull it straight out to detach the four ball studs on the front cover from the ball stud sockets on the front of the upper blower module bay and power shelf.

Step 2 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis. (See Figure 3.)

Step 3 To turn off the power entry module and eject it from the shelf backplane connector, follow these steps:

(a) Loosen the captive screw on the ejector lever to release the ejector lever from the power entry module faceplate. (See Figure 4a.)

(b) Pivot the ejector lever away from the power entry module faceplate to eject the power entry module from the power shelf backplane connector. (See Figure 4b.)

Note

Step 4 Grasp the power entry module handle and pull the power entry module halfway out of the bay. (See Figure 4c.)

Caution The DC-input power entry module weighs 6.4 lb (2.9 kg). Because of the weight of the power entry module and the elevated position of the power shelf, you should use two hands when handling the power entry module.

Step 5 Use your free hand to support the power entry module while you slide the power entry module completely out of the bay.

Step 6 Set the defective power entry module safely aside.

If you plan to return the defective power entry module to the factory, repackage it in the shipping container you received with the replacement power entry module.

Installing the Replacement DC-Input Power Entry Module

Figure 5 shows the steps in installing the replacement DC-input power entry module in the power shelf.

Figure 5: Installing the Replacement DC-Input Power Entry Module

To install a replacement DC-input power entry module, use Figure 5 as a reference and follow these steps:

Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis. (See Figure 3.)

Step 2 Loosen the captive screw on the ejector lever on the replacement power entry module and pivot the ejector lever away from the power entry module faceplate until it is perpendicular to the power entry module faceplate. (See Figure 5a.)

Caution To prevent damage to the power shelf backplane connector, do not use excessive force when inserting a power entry module into its power shelf bay.

Step 3 Using two hands to support and guide the power entry module, slide it into the power shelf bay until the connector on the back of the power entry module makes contact with the connector in the back of the power shelf.

Step 4 Seat the power entry module in the backplane connector by pivoting the ejector lever to engage the slot in the floor of the power shelf and then pushing the ejector lever until it is flush with the power entry module faceplate. (See Figure 5c.)

Note

Step 5 Tighten the captive screw on the ejector lever.

Step 6 Replace the front cover over the upper blower module bay and power shelf.

Step 7 Verify that the source DC circuit breakers servicing the source DC cables for the power shelf are switched on.

Checking the Replacement of a DC-Input Power Entry Module

To check the power entry module installation, follow these steps:

Step 1 Verify that each of the following conditions is true:

Each power entry module is inserted all the way into its bay, and the ejector lever is secured by its captive screw.
All source DC power cable lugs are securely attached to the threaded terminals on the back panel of the power shelf.
At the source DC end of the power cable, the cable is securely attached to the source DC circuit breaker.
The source DC voltage is within the range indicated on the power entry module.
The source DC cable pair for each power entry module bay must be connected to a dedicated 60A DC service.

Step 2 Visually check that the green LED labeled PWR OK goes on and stays on. This LED indicates that the source DC voltage is within the correct range

If the LED labeled PWR OK is off, verify the following:

The source DC circuit breaker is switched on.
The source DC end of the power cable is securely attached to the source DC circuit breaker, and the source DC power cable leads are securely attached to the threaded terminals on the back panel of the power shelf.

Step 3 Verify that the amber LEDs labeled FAULT and TEMP are off.

If the LED labeled FAULT remains on, replace the existing power entry module with a spare power entry module. If the LED labeled PWR OK on the spare power entry module goes on, return the faulty power entry module for replacement.

If the LED labeled FAULT on the spare power entry module remains on, suspect a faulty power shelf backplane connector in that power shelf bay.

Step 4 Replace the front cover over the top blower module bay and power shelf.

If the power entry module fails to operate properly after several attempts to power it up, contact a service representative for assistance.
