Upgrading MCI Cards from Microcode Versions 1.5, 1.7, 1.8, 1.9, and 1.10 to Microcode Versions 1.11 or 1.11A

Product Numbers: MC-MCI-V1.11= and MC-MCI-V1.11A=

This document describes how to upgrade the microcode on Revision 2 and Revision 3 multiport communications interface (MCI) cards from Microcode Versions 1.5, 1.7, 1.8, 1.9/1.9A, or 1.10/1.10A to Microcode Version 1.11/1.11A.

For the MCI microcode upgrades, the following statements apply to both card types:

• If you are upgrading from Version 1.5, you need the MC-MCI-V1.11 kit, and you use all 16 components in the kit.

• If your current microcode is earlier than Version 1.5, contact a service representative for information on microcode upgrades.

• If you are upgrading from a CSC/2 processor card to a CSC/3 or CSC/4 processor card, in addition to the MCI microcode, you will need the bus-timing programmable array logic (PAL) device (Part Number 17-0675 in MC-MCI-V1.11), which is listed in Table 1 at the end of this document.

• If you are upgrading an Ethernet-only MCI card, use the MC-MCI-V1.11A kit, which does not contain Rockwell components. (Note that if you need to install an MC-MCI-V1.11 kit on an Ethernet-only MCI card, you will not need to install the Rockwell components included in the kit.)

Determining System Compatibility

You can determine the MCI card type (1.0 or 1.1) and its current microcode version in two ways: either inspect the card or display the information using the EXEC command show controller mci.

To inspect the card, first remove it from the card cage. Examine the silkscreened label along the right side of the card: the cards are marked Rev./3 for the card type 1.1, and Rev./2 for the card type 1.0. Examine the microcode EPROMs to determine the microcode version.

To display the type and current microcode version on the screen, enter the EXEC command show controller mci. When an MCI Rev./ 3 (controller type 1.1) card is installed, the first line of the display for each installed MCI card (MCI 0, MCI 1, and so on) should be as follows:

When an MCI Revision 2 (Controller Type 1.0) card is installed, the first line of the display for each installed MCI card (MCI 0, MCI 1, and so on) should be as follows:

Verify that the microcode version is at least 1.5 or 1.10. If it is not, contact a customer service representative for information on microcode upgrades for the Type 1.0 MCI card.

Preventing Electrostatic Discharge Damage

Electrostatic discharge damage (ESD) occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. ESD can impair electronic circuitry and equipment. Always follow ESD prevention procedures when removing and replacing cards. Following are steps for handling printed circuit cards:

Step 1 Slip on an ESD-preventive wrist strap, ensuring that it makes good skin contact.

Step 2 Connect the strap to an unpainted chassis frame surface or another proper grounding point or surface to safely channel unwanted ESD voltages to ground.

Step 3 Use the ejector levers to remove the card. Handle the card by its edges. Place the card on an antistatic surface or in a static shielding bag. To prevent further damage to the card by ESD voltages, defective cards must remain in the static shielding bag when returned for repair or replacement.

Step 4 Handling the new card by its edges only, insert it into the chassis. Avoid contact between the card and clothing. The wrist strap only protects the card from ESD voltages on the body; ESD voltages on clothing can still damage the card.

Caution  For safety, periodically use an ohmmeter to check the ESD-preventive wrist strap to ensure that the resistor is providing proper ESD protection. The measurement should be between 1 and 10 megohms.

Opening the Chassis

Remove the front access panel to access the cards in the card cage and remove the top cover to access the other chassis components. The following procedures include instructions for both. Use the appropriate procedure for your chassis type.

Tools Required

You will need the following tools to access the chassis interior:

• Screwdrivers: small and medium flat-blade and number 1 and number 2 Phillips

• ESD-preventive wrist strap

A-Type Chassis Access Procedure

Following is the procedure for accessing the A-type chassis interior.

Warning Before accessing the chassis interior, turn off power to the chassis and unplug the power cord because hazardous voltages may exist in or near the power supply. Use extreme caution when working near the power supply.

Step 1 Turn OFF power to the chassis, and unplug it from AC power.

Step 2 If the chassis is rack mounted, disconnect all external cables from the chassis rear panel. Note where these cables were connected, for reinstallation.

Step 3 Remove the chassis from the rack and transfer it to a desktop or worktable.

Step 4 If you will need to handle any electronic components (cards, and so forth), attach appropriate ESD protection and attach the AC power cord but, to prevent a shock hazard, make certain the chassis power is OFF.

Step 5 To access cards in the card cage, loosen the two thumbscrews on the front access panel and remove the panel from the chassis. (See Figure 1.) If you need to access cards in the card cage only, omit the next step.

Step 6 To access other system components, locate and remove the seven number 1 Phillips screws securing the top cover. (See Figure 1.) Remove the top cover, and set it and the screws aside.

MGS Chassis Access Procedure

Following is the procedure for accessing the MGS chassis interior.

Warning Before accessing the chassis interior, turn off power to the chassis and unplug the power cord because hazardous voltages may exist in or near the power supply. Use extreme caution when working near the power supply.

Step 1 Turn OFF power to the chassis and unplug it from AC power.

Step 2 If the chassis is rack mounted, disconnect all external cables from the chassis rear panel. Note where these cables were connected, for reinstallation.

Step 3 Remove the chassis from the rack and transfer it to a desktop or worktable.

Step 4 If you need to handle any electronic components (cards, and so forth), attach appropriate ESD protection and attach the AC power cord but, to prevent a shock hazard, make certain the chassis power is OFF.

Step 5 To access the cards in the card cage, locate the three flat-blade screws that secure the card cage access panel. (See Figure 2.) These screws are located on the top of the MGS chassis access panel.

Step 6 Using the flat-blade screwdriver, turn each of these screws 1/4 to 1/2 turn counterclockwise until the screw pops up.

Step 7 Using the number 2 Phillips screwdriver, loosen the three screws at the bottom edge of the card cage cover. (Do not remove these screws completely.) Carefully remove the card cage cover and set it aside.

Step 8 To access the other chassis components, use the number 1 Phillips screwdriver to remove the 14 screws that secure the top cover of the MGS chassis. (See Figure 2.) Remove the top cover and set it aside.

C Chassis Access Procedure

Following is the procedure for accessing the C chassis interior.

Warning Before accessing the chassis interior, turn off power to the chassis and unplug the power cord because hazardous voltages may exist in or near the power supply. Use extreme caution when working near the power supply.

Step 1 Turn OFF power to the chassis and unplug it from AC power.

Step 2 If you need to handle any electronic components (cards, and so forth), attach appropriate ESD protection and attach the AC power cord but, to prevent a shock hazard, make certain the chassis power is OFF.

Step 3 Turn the chassis over so that the bottom is facing up. Use the number 2 Phillips screwdriver to remove the ten screws that secure the cover of the C chassis. There are two screws on each side and six screws on the bottom of the chassis. (See Figure 3.)

Step 4 Turn the chassis back over and position it so that the back (the side with the ports) is on your left and the front of the chassis (with the LED) is on your right. (This is completely opposite of the chassis position shown in Figure 3.)

Step 5 While holding the back of the chassis with your left hand, pull the front of the cover to the right until the power supply and card cage are completely exposed. Because the fit is snug, pull slowly and carefully, and do not remove the cover.

Caution  Several cables are located close to the interior of the C chassis cover. Avoid damage to these cables by ensuring that they do not impede the cover as you slide it.

Replacing the Components

To replace the MCI cards, you need some or all of the following:

• To upgrade from Version 1.5, you need the MC-MCI-V1.11 kit and will use all 16 components in the kit.

• To upgrade from a CSC/2 processor card to a CSC/3 or CSC/4 processor card, in addition to the MCI microcode, you will need the bus-timing programmable array logic (PAL) device (Part Number 17-0675 in MC-MCI-V1.11), which is listed in Table 2 and Table 1.

• If you are upgrading Ethernet-only MCI cards (CSC-1E or CSC-2E), you will not need the Rockwell components from the MC-MCI-V1.11 kit.

• ESD-preventive wrist strap.

• Chip extractor (IC removal tool). If one is not available, you can use a flat-blade screwdriver.

• Needlenose pliers.

Caution To prevent ESD damage, refer to the section "Preventing Electrostatic Discharge Damage."

The following procedure is for upgrading both MCI type 1.0 and 1.1 cards. The microcode components are in the same locations on both cards; however, the socket numbers are different. Illustrations and tables indicating the correct socket designations are provided for each card. Ensure that you are referring to the correct illustration and table when placing the components in the sockets.

Step 1 Turn OFF power to the system but, to channel ESD voltages to ground, do not disconnect the power cord.

Step 2 Open the chassis using one of the procedures in the section "Opening the Chassis."

Step 3 Put on the ESD-preventive wrist strap provided with the upgrade kit, or use your own grounding strap. Attach the equipment end of the strap to an unpainted area on the chassis.

Step 4 Disconnect the internal ribbon cables that are attached to the front of the MCI card. If other cables (to other cards) are in front of the MCI card and prevent you from removing it, note the card and port locations of each before disconnecting them (to avoid misrouting cables when you reinstall the card).

Step 5 Use your thumbs to pull the ejector levers out and away from the card edge to loosen it; then pull the card out of its slot. Place the card on an antistatic mat.

Step 6 Locate the 16 components to be replaced (14 on cards with Ethernet only).

Step 7 Remove each of the old components with the chip extractor. If one is not available, use a flat-blade screwdriver to gently pry each component out of its socket.

Step 8 Insert the new components into the appropriate sockets, as follows:

• For type 1.0 MCI cards, use Figure 4 and Table 1.

• For type 1.1 MCI cards, use Figure 5 and Table 2.

• Align the notch on each component with the notch on the corresponding socket. (See or Figure 4 or Figure 5.)

Caution Be careful not to bend or crush any of the pins when inserting the new components. If any pins become bent, use needlenose pliers to straighten the pins; then carefully reinsert the component. If a component is installed backwards when power is turned ON, the component will be damaged. Contact a customer service representative to obtain a replacement.

Step 9 When all of the components are replaced, reinsert the card, reconnect the internal cables, replace the access panel, and restart the system.

Step 10 Enter the EXEC command show controller mci. The first line of the display for each installed MCI card should be as follows:

MCI 0, controller type 1.n, microcode version 1.11 (where n is 1 or 0)

Step 11 Use the display from the show controller mci command to verify that the microcode version is 1.11.

This completes the microcode upgrade procedure.
