MIC-C/T/P Front Mount Electrical Connection Card Description

The MIC-C/T/P card (Figure 1) provides connection for one of the two possible redundant power supply inputs. It also provides connection for system management serial port, system management LAN port, modem port (for future use), and system timing inputs and outputs. Its position is in slot 24 in the center of the ONS 15454 SDH subrack EFCA area.


Note Cisco does not recommend nor support operating the ONS 15454 SDH with only one of the MIC-A/P respectively MIC-C/T/P cards. Besides missing power supply redundancy, additional functions of the other card would be missing. To safeguard your system, always operate in a redundant configuration.



Note For proper system operation, both the MIC-A/P card and the MIC-C/T/P card must be installed in the shelf.


Figure 1 shows the MIC-C/T/P faceplate. Figure 2 shows the block diagram.

The following list summarizes MIC-C/T/P card features:

Connection for one of the two possible redundant power supply inputs

Connection for two serial ports for local craft / modem (for future use)

Connection for the LAN port

Connection for two system timing inputs

Connection for two system timing outputs

Storage of manufacturing and inventory data

MIC-C/T/P Card-Level Indicators

The MIC-C/T/P card has a pair of LEDs, located on the RJ45 LAN connector. The green LED is illuminated when a link is present, and the yellow LED is illuminated when data is being transferred.

Safety: IEC 60950, EN 60950, UL 60950, CSA C22.2 No. 60950, TS 001, AS/NZS 3260

Installation Procedures

Use this section if you are installing or removing the MIC-C/T/P card for the first time. After you become familiar with ONS 15454 SDH card installation and boot up, use this section as a reference.


Caution Always use the supplied electrostatic discharge (ESD) wristband when working with an ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the lower right outside edge of the shelf assembly and ensure the shelf assembly is properly grounded.


Caution Hazardous voltage or energy may be present on the backplane when the system is operating. Use caution when servicing.


Step 1 Carefully insert the card into the rails of slot 24 (Figure 3).

Step 2 Move the upper ejector down and the lower ejector up to enable the card being inserted into the backplane connectors.

Step 3 Gently push the card into the connector on the back plane.

Step 4 Tighten the front mounting screws with a Phillips or slot screwdriver.


MIC-C/T/P cards have electrical plugs that plug into electrical connectors on the shelf assembly backplane. When the ejectors are fully closed and the mounting screws are tightened, the card plugs into the shelf assembly backplane. Figure 3 shows general card installation. Connecting the power cable is described in Chapter 1 "Installation" of the Cisco ONS 15454 SDH Installation and Operations Guide.

Card Turn Up

Follow the steps in this section to verify card turn up. If one or more of the Cisco Transport Controller (CTC) software screen conditions according to "Verify Successful Turn Up of the MIC-C/T/P Card" section are not met, re-install the card. Replace the unit if the faulty state persists.

Verify Successful Turn Up of the MIC-C/T/P Card


Step 1 Verify that power is applied to the shelf assembly.

Step 2 Verify that the MIC-C/T/P card has been installed in slot 24.

Step 3 Verify that the card appears in slot 24 on the CTC software screen.

Step 4 Verify that the card is white on the CTC software screen.

Step 5 Verify that the card is shown in Inventory on the CTC software screen.


Removal Procedures

Use this section if you are installing or removing the MIC-C/T/P card for the first time. After you become familiar with ONS 15454 SDH card installation and boot up, use this section as a reference.


Caution Always use the supplied electrostatic discharge (ESD) wristband when working with an ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the lower right outside edge of the shelf assembly and ensure the shelf assembly is properly grounded.


Caution Hazardous voltage or energy may be present on the backplane when the system is operating. Use caution when servicing.


Step 1 If there is traffic on the system, make sure that the redundant power supply input on the MIC-A/P card is properly powered.


Note Failure to do so will result in loss of traffic.



Caution To avoid risk of burn, turn off the power source circuit breaker before disconnecting the power cable.

Step 2 Disconnect all the cable connectors from the MIC-C/T/P card to be removed. Do not forget to mark all the connectors or cables for correct reinstallation afterwards.


Note To disconnect the coaxial cable from the FMEC, first pull the outer ring of the connector, then pull the connector. Pulling the cable without first having pulled the outer ring of the connector to release its locking can result in damage to the cable or the connector or both.


Step 3 Loosen the front mounting screws (Figure 3).

Step 4 Move the upper ejector up and the lower ejector down to extract the card from the backplane connectors.

Step 5 Carefully remove the card from the shelf.
