Product Numbers: MC-MEC5.1-V2.4= and MC-MEC5.1-V10.3=
This publication describes how to upgrade the Type 5.1 multiport Ethernet controller cards to Microcode Version 2.4 or Microcode Version 10.3.
Microcode Version 2.4 is compatible only with the first generation ciscoBus controller card (CSC-CCTL). Microcode Version 10.3 is compatible with, and required for use with, the second-generation ciscoBus controller card (CSC-CCTL2). If you are replacing a CSC-CCTL card with a CSC-CCTL2 card, you must upgrade the microcode on all ciscoBus interface cards to Version 10.0 or later.
Compatibility requirements for the CSC-CCTL2 are described in the section "Verifying CCTL2 CompatibilityMicrocode Version 10.0 or Later Only."
In the following sections of this publication, the term MEC is used to indicate the CSC-MEC (used with first-generation ciscoBus) and CSC-C2MEC (used with second-generation ciscoBus) cards, unless otherwise indicated.
Microcode Version 2.4 and Microcode Version 10.3 are used with the Type 5.1 MEC card (Revision E or above). Earlier revisions of the card (Revisions A, C, or D, all of which are MEC card Type 5.0) are not compatible with the microcode versions described in this publication.
If you have a MEC Type 5.0 card, you must upgrade the card to a Type 5.1 card before installing either of these microcode versions. Instructions for determining the revision level of your current card are provided in the section "System Compatibility."
The upgrade procedure is the same for both microcode versions; only the component part numbers are different. References to part number tables are provided in the appropriate steps in the procedure.
Read the requirements and procedures in this section to ensure that your MEC card is compatible with the new microcode and that you have the proper tools and parts to complete this procedure without interruption.
Your current system must meet the following compatibility requirements before you install the new microcode:
The Microcode Release Note publication (Document Number 78-1069-xx--where xx is the latest version) provides the latest information on both the recommended and minimum required microcode versions for using all cards with Software Release 8.2 through Software Release 9.21. If the latest microcode version implements features that you are not using in your system and you already have the minimum required microcode version installed, there is no requirement to update the microcode.
New microcode versions occasionally fix bugs and provide performance enhancements in addition to implementing new features, and you will obtain maximum performance and reliability by upgrading to the latest recommended version.
Determine the card type (5.0 or 5.1) and microcode version (1.6 through 10.1) of all installed MEC cards with the show controller cbus command. You can also view the card type and the card revision level (A, C, D, E, or above) printed on the part number label, which is located on one of the ejector tabs and is visible when the card is installed in the card cage.
To display card type and microcode version, enter the show controller cbus command. The first line of the display for each installed MEC card (MEC 0, MEC 1, and so forth) should indicate a card Type 5.1.
The following example shows an MEC card and a first generation ciscoBus card (CSC-CCTL):
Router# show cont cbus
cBus 1, controller type 3.0, microcode version 2.0
[text omitted]
MEC 0, controller type 5.1, microcode version 2.3
Verify that the MEC card type is 5.1, and the microcode version is 2.1 or later. If not, you must upgrade your card before proceeding. Contact a customer service representative for upgrade information.
The label showing the version is affixed to one of the ejector tabs on the front edge of the card; it is not necessary to remove the card to see the label. To view the label, you must first remove the chassis front access panel as described in steps 1 and 2 of the section "Microcode Upgrade Procedure."
The CSC-CCTL2 card is required to run ciscoBus network interface cards (with the C2 designator). The C2 indicates that a ciscoBus card is running Microcode Version 10.0 or later and is, therefore, compatible with the CSC-CCTL2 card.
For example, when the microcode on an MEC card is first changed to Version 10.0, the name of the card changes from CSC-MEC to CSC-C2MEC to indicate that it is CCTL2-compatible. If you are installing a new CSC-CCTL2, you must upgrade all ciscoBus interface cards to Microcode Version 10.0 or later. These cards and their compatibilities are listed in Table 1.

Before opening the chassis, refer to the section "System Compatibility" on page 2 and ensure that your system meets the minimum requirements for the microcode version you are installing.
To perform this upgrade, you need the following:
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 ejectors to remove the card. Handle the card by its sides. 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.
 | Warning Use an ohmmeter to check the ESD-preventive wrist strap to ensure that the resistor is providing proper ESD protection. For safety, the measurement should be between 1 to 10 mega ohms. |
Following are the procedures for upgrading the microcode on the MEC and C2MEC Type 5.1 cards:
 | Caution Before performing these installation procedures, turn off power to the system because removing or installing a card in the backplane while the system power is on can severely damage the card and can also damage other system components. |
Step 1 Turn OFF the system power, but to channel ESD voltages to ground, do not disconnect the power cord.
Step 2 Loosen the two thumb fasteners and remove the front access panel to expose the card cage. The thumb fasteners are tightened with 12 inch/lb of torque for shipping. If you are removing the front panel for the first time, use a medium flat-blade screwdriver to turn the thumb fasteners counterclockwise to loosen. When you replace the panel, turn the thumb fasteners clockwise until finger-tight.
| Caution Observe proper ESD prevention procedures when handling cards and components to prevent damage from electrostatic discharge. |
Step 3 Put on the ESD-preventive wrist strap provided with the upgrade kit, or use your own grounding strap. Attach the equipment end to an unpainted area on the chassis.
Step 4 Disconnect the internal ribbon cables that are attached to the front of the MEC card. If other cables (to other cards) prevent you from removing the MEC card, 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 tabs 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 Refer to Figure 1 for the socket locations of the 11 microcode components to be replaced. Refer to the following for component part numbers:
Step 7 Remove each of the old components with a chip extractor. If one is not available, use a flat-blade screwdriver to remove the components.
Step 8 Insert the new components into the appropriate sockets, as shown in Figure 1 and listed in the following tables. Align the notch on the component with the notch on its socket, as shown.
Step 9 Be careful not to bend or crush any of the pins when inserting the new components. If any pins are bent, use needle-nose pliers to straighten the pins, then carefully reinsert the component.
If a pin breaks or if power is turned on with a component installed backwards, the component must be replaced. Contact a service representative for a replacement.
Step 10 After all 11 components are replaced and the pins checked, reinsert the card, reconnect the internal cables, and restart the system for an installation check.

After you reinstall the upgraded MEC card and reconnect the internal ribbon cables, test the installation (before you replace the front panel) by observing the following LED indicators:
The ciscoBus card (CSC-CCTL or CSC-CCTL2) is always installed in the center ciscoBus slot (Multibus slot number 7), as shown in Figure 2. After verifying that the LEDs go on correctly, use the show controller cbus command to display the new microcode version.
The bank of indicators used on the CSC-CCTL is different from that on the CSC-CCTL2. Descriptions of both types of ciscoBus controllers follow. Review them so that you can anticipate how the LED indicators should go on. Before turning on the chassis power to check the installation, note the ciscoBus slot number(s) that contain the MEC card(s) you just reinstalled. (Figure 2 shows the ciscoBus slot numbers and locations.)
The CSC-CCTL contains a bank of 16 LEDs as shown in Figure 3: four sets of four LEDs, one set for each interface slot in the ciscoBus. Figure 3 shows the LEDs as viewed with the card installed in the card cage--edge on, component-side up. In the illustration, the numbers above each LED indicate the corresponding ciscoBus slot number. (Slot numbers and locations are shown in
Figure 2.) Only the first (far left) LED in each set of four is used as an indicator that goes on when an interface is present in a ciscoBus slot. At power-up, all the LEDs are on, indicating that the CSC-CCTL card is active. When the system boot completes, only those LEDs that indicate the presence of a card in the corresponding ciscoBus slot should be on; the LEDs for empty ciscoBus slots should be off.
The CSC-CCTL2 contains a bank of 5 LEDs, one red indicator for each ciscoBus slot and one green OK indicator. Figure 4 shows the indicators as viewed with the card installed in the card cage--edge on, component-side up. In the illustration, the numbers above each LED indicate the corresponding ciscoBus slot number. (Slot numbers and locations are shown in Figure 2.) At power-up, all the LEDs should be on, indicating that the CSC-CCTL2 card is active. When the system boot completes, only those LEDs that indicate the presence of a card in the corresponding ciscoBus slot should remain on; the LEDs for empty ciscoBus slots should be off.
Also observe the LEDs on the MEC card you just reinstalled. An LED is located next to each port, as shown in Figure 5. After the system boots, the LED for each connected port should be on.
Verify correct installation of the new microcode components with the following steps.
Step 1 Turn ON the system power. Verify that all the LEDs on the ciscoBus card (CSC-CCTL or CSC-CCTL2) are on according to the previous description of each.
Step 2 CSC-CCTL2 only--When the system has completed its boot cycle (indicated by a beep), verify that the far right, green OK LED indicator goes on and remains on. If it does not go on, check the following:
Step 3 When the system completes its boot cycle, check the four red indicators on the ciscoBus controller card. (Refer to the section "Checking LEDs" on page 8 if necessary.) Ensure that the LED indicator for each occupied ciscoBus slot is on. In particular, check the slots for all MEC cards you just reinstalled. If the LEDs do not go on properly, check the following:
Step 4 Check the LEDs on the MEC card. The LED indicator for each connected port should be on. (See Figure 5.) If they do not go on, check the following:
If the LEDs do not go on correctly after checking all of the connections, contact a service representative for information on how to proceed.
To display the new microcode version, enter the show controller cbus command. The first line of the display for each installed MEC card should indicate the new microcode version, as follows:
cBus 1, controller type 3.0, microcode version 2.0
[text omitted]
MEC 0, controller type 5.1, microcode version 2.4
ciscoBus 1, controller type 6.0, microcode version 11.0
[text omitted]
MEC 0, controller type 5.1, microcode version 10.3
After the installation checks out successfully, replace the front access cover and finger-tighten the two thumb fasteners.
This completes the Microcode Version 2.4 or 10.3 upgrade procedure.
