FMEC-E3/DS3 Front Mount Electrical Connection Card Description

The ONS 15454 SDH FMEC-T54-E1 card provides front mount electrical connection for twelve ITU-compliant, G.703 E-3 or DS-3 ports. With FMEC-E3/DS3, each interface of an E3-12 card operates at 34.368 MBits/s (Mbps), resp. each interface of a DS3I-N-12 card operates at 44.736 MBits/s (Mbps) over a 75 ohms unbalanced 1.0/2.3 miniature coax connector. Figure 1 shows the FMEC-E3/DS3 faceplate and Figure 2 shows a block diagram of the card.

You can install the FMEC-E3/DS3 card in any EFCA (Electrical Facility Connector Assy) slot from slot 18 to 22 or slot 25 to 29 on the ONS 15454 SDH. Each FMEC-E3/DS3 card interface features E3-level or DS3-level inputs and outputs supporting cable losses of up to 12 dB @ 17184 kHz for E3 signals, up to 137 m (450 ft.) 734A, RG59, 728A / 24 m (79 ft.) RG179 for DS3 signals .

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 FMEC-E3/DS3 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-E3/DS3 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-E3/DS3 Card" section are not met, re-install the card. Replace the unit if the faulty state persists.

Verify Successful Turn Up of the FMEC-E3/DS3 Card


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

Step 2 Verify that the FMEC-E3/DS3 card has been installed in the correct slot (Slot 18 to 22 or 25 to 29, for the E3-12 or DS3I-N-12 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-E3/DS3 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 all the coaxial cables with 1.0/2.3 miniature coax connectors from the FMEC card to be removed. Do not forget to mark all the connectors or cables for correct reinstallation afterwards.


Note To disconnect the 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.
