FMEC-DS1/E1 Front Mount Electrical Connection Card Description

The ONS 15454 SDH FMEC-DS1/E1 card (Figure 1) provides front mount electrical connection for fourteen ITU-compliant, G.703 E-1 ports. With FMEC-DS1/E1, each E1-N-14 port operates at 2.048 MBits/s (Mbps) over a 120 ohms balanced cable via two 37-pin DB connectors.

Caution These E1 ports on the FMEC-DS1/E1 interface card are only capable to be connected to SELV circuits. The E1 interface is not intended for connection to any Australian Telecommunications networks without written consent of the network manager.

Figure 1 shows the FMEC-DS1/E1 faceplate. Figure 2 shows the block diagram.

Installation Procedures

Use this section if you are installing or removing the FMEC-DS1/E1 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 the desired slot (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.

FMEC-DS1/E1 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.

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 FMEC-DS1/E1 Card" section are not met, re-install the card. Replace the unit if the faulty state persists.

Verify Successful Turn Up of the FMEC-DS1/E1 Card

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

Step 2 Verify that the FMEC-DS1/E1 card has been installed in the correct slot (Slot 18 to 22 or 25 to 29, for the E1-N-14 card in slot 1 to 5 or 13 to 17, respectively).

Step 3 Verify that the card appears in the correct slot 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 FMEC-DS1/E1 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 card, route this traffic to other interfaces.

Step 2 Disconnect the cables with 37-pin DB connectors from the FMEC card to be removed. Do not forget to mark the connectors or cables for correct reinstallation afterwards.

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.
