Safety Guidelines

Preventing Electrostatic Discharge

Required Tools and Equipment

Safety Guidelines

Before you perform any procedure in this publication, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment.

The following guidelines are for your safety and to protect equipment. The guidelines do not include all hazards. Be alert.


Note Review the safety warnings listed in the Regulatory Compliance and Safety Information for Cisco 12000 Series Internet Router publication (Document Number 78-4347-xx) that accompanied your router before installing, configuring, or maintaining a line card.


Keep the work area clear and dust free during and after installation. Do not allow dirt or debris to enter into any laser-based components.

Do not wear loose clothing, jewelry, or other items that could get caught in the router while working with line cards.

Cisco equipment operates safely when it is used in accordance with its specifications and product usage instructions.

Preventing Electrostatic Discharge

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Electromagnetic interference (EMI) shielding is an integral component of the line card. Cisco recommends using an ESD-preventive strap whenever you are handling network equipment or one of its components.

The 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 connection socket on the router or to bare metal on the chassis.

Handle MSBs by the captive installation screws, the provided handle, the ejector levers, or the line card metal carrier only; avoid touching the board or connector pins.

Place removed MSBs 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 the MSBs and clothing. The wrist strap protects the board only from ESD voltages on the body; ESD voltages on clothing can still cause damage.


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

Required Tools and Equipment

You need the following tools and parts to remove and install MSBs:

Flat-blade or Phillips screwdriver

ESD-preventive wrist or ankle strap and instructions


Note If you need additional equipment, see Cisco.com or your service representative for ordering information.


Removing and Installing an MSB

The following sections provide procedures for removing or installing an MSB:

Guidelines for MSB Removal and Installation

Removing an MSB

Installing an MSB


Note See the "Guidelines for MSB Removal and Installation" section before removing an MSB while power to the router is on.


Guidelines for MSB Removal and Installation

Guidelines for MSB removal and installation include the following:

Online insertion and removal (OIR) is supported, enabling you to remove and install cards while the router is operating. OIR is seamless to users on the network, maintains all routing information, and ensures session preservation.

After you reinstall an MSB, the router automatically downloads the necessary software from the route processor (RP).


Caution The router may indicate a hardware failure if you do not follow proper procedures. Remove or insert only one line card at a time. Allow at least 15 seconds for the router to complete the preceding tasks before removing or inserting another line card.

After removing and inserting a line card into the same slot, allow at least 60 seconds before removing or inserting another line card.

MSB cards have two ejector levers to release the card from its backplane connector. Use the levers when you are removing the card and to seat the card firmly in its backplane connector when you are installing the MSB. The ejector levers align and seat the card connectors in the backplane.


Caution When you remove an MSB, always use the ejector levers to ensure that the connector pins disconnect from the backplane in the sequence expected by the router. Any card that is only partially connected to the backplane can halt the router.

When you install an MSB, always use the ejector levers to ensure that the card is correctly aligned with the backplane connector; the connector pins should make contact with the backplane in the correct order, indicating that the card is fully seated in the backplane. If a card is only partially seated in the backplane, the router hangs and subsequently crashes.

Removing an MSB

If you are replacing a failed MSB, remove the existing MSB first, then install the new MSB in the same slot. To remove an MSB, use Figure 2 as a reference and follow these steps:


Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.

Step 2 Use a screwdriver to loosen the captive screw at each end of the line card faceplate. (See Figure 2a.)

Figure 2 Line Card Removal and Installation


Caution When you remove an MSB, always use the ejector levers to ensure that the card connector pins disconnect from the backplane in the logical sequence expected by the router. Any card that is only partially connected to the backplane can halt the router.

Step 3 Simultaneously pivot the ejector levers away from each other to release the MSB from the backplane connector. (See Figure 2b.)

Step 4 Grasp the ejector levers and pull the MSB halfway out of the slot.

Step 5 Grasp the MSB and gently pull it straight out of the slot, keeping your other hand under the card to guide it. (See Figure 2c.) Avoid touching the MSB printed circuit board, components, or any connector pins.

Step 6 Place the removed MSB on an antistatic mat, or immediately place it in an antistatic bag if you plan to return it to the factory.

Step 7 If the MSB slot is to remain empty, install a line card blank (Product Number MAS-GSR-BLANK) to keep dust out of the chassis and to maintain proper airflow through the line card compartment. Secure the line card blank to the chassis by tightening its captive screws.


Installing an MSB

The MSB slides into almost any available line card slot and connects directly to the backplane. If you install a new MSB, you must first remove the line card blank from the available slot.


Note Refer to the installation and configuration guide for your router for information on line card slot types, slot width, and slot location.



Caution The router may indicate a hardware failure if you do not follow proper procedures. Remove or insert only one card at a time. Allow at least 15 seconds for the router to complete the preceding tasks before removing or inserting another line card.

To install the MSB, follow these steps:


Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.

Step 2 Choose an available line card slot for the MSB.


Caution To prevent ESD damage, handle cards by the captive installation screws, the provided handle, the ejector levers, or the card carrier edges only. Do not touch any of the electrical components or circuitry.

Step 3 Grasp the faceplate (or handle) of the MSB with one hand and place your other hand under the card carrier to support the weight of the card; position the card for insertion into the card cage slot. Avoid touching the MSB printed circuit board, components, or any connector pins.

Step 4 Carefully slide the MSB into the slot until the ejector levers make contact with the edges of the card cage, then stop when the ejector lever hooks catch the lip of the card cage. If they do not catch, try reinserting the MSB until the ejector lever hooks are fully latched. (See Figure 3.)

Figure 3 Ejector Levers


Caution When you install a MSB, always use the ejector levers to ensure that the card is correctly aligned with the backplane connector, that the card connector pins make contact with the backplane in the correct order, and that the card is fully seated in the backplane. A card that is only partially seated in the backplane can cause the router to hang and subsequently crash.

Step 5 Simultaneously pivot both ejector levers toward each other until they are perpendicular to the MSB faceplate. This action firmly seats the card in the backplane.

Step 6 Use a 3/16-inch flat-blade screwdriver to tighten the captive screw on each end of the MSB faceplate to ensure proper EMI shielding and to prevent the MSB from becoming partially dislodged from the backplane.


Caution To ensure adequate space for additional line cards, always tighten the captive installation screws on each newly installed card before you insert any additional cards. These screws also prevent accidental removal and provide proper grounding and EMI shielding for the router.


For information on verifying and troubleshooting the hardware installation, see the "Verifying and Troubleshooting the MSB Installation" section.

Verifying and Troubleshooting the MSB Installation

The following sections describe how to verify and troubleshoot the MSB installation:

Initial Boot Process

Alphanumeric LED Descriptions

Troubleshooting the Installation

Initial Boot Process

During a typical MSB boot process, the following events occur:

1. The MSB maintenance bus (Mbus) module receives power and begins executing the Mbus software.

2. The MSB Mbus module determines the type of card on which it resides, performs internal checks, and prepares to accept the Cisco IOS XR software from the RP.

3. The RP powers up the MSB and loads it with its Cisco IOS XR software.

To verify that the MSB is working properly, perform the following operational check:

During the MSB boot process, observe the alphanumeric LEDs to ensure that the card is running the typical initialization sequence. The sequence should end with "IOS-XR."

If this condition is not met, refer to Troubleshooting the Installation to identify any possible problems.

Alphanumeric LED Descriptions

The MSB includes an alphanumeric LED display consisting of four characters arranged in two rows (upper and lower). In general, the LEDs do not come on until the RP recognizes and powers up the card. As it boots, the line card displays a sequence of messages. Table 1 lists the alphanumeric LED messages that may appear on the MSB.

Table 1 Alphanumeric LED Messages 

Message
Description

Upper row: SP
Lower row: RMON

Upper row: IOS-
Lower row: XR

Indicates that the node is up and running.

Upper row: PRES
Lower row: ENT

Indicates that the card is plugged in but is not booted (probably due to a configuration issue or some other issue with the card).

Upper row: IN-R
Lower row: ESET

Indicates that the card either encountered critical alarms and, therefore, was shut down or failed the boot process and was shut down. Manual intervention is required to recover the card.

Upper row: ROMM
