Step 3 Use a tape measure and level to ensure that the external power shelf is installed straight and level.
Step 4 Remove the spacer bar after the external power shelf is secured to the rack.
Connecting DC-Input Power from the 15540-ACPS-N-E External Power Shelf
To apply DC-input power to your Cisco ONS 15540 shelf, you must install a cable strain relief bracket and two DC power cables. The two DC power cables are connected to each other at the cable strain relief bracket. To complete the connections, follow these steps:
Step 1 Attach the cable strain relief bracket to the side of the Cisco 15540 chassis. (See Figure 2-21.)
Figure 2-21 Installing the Cable Strain Relief Bracket
Step 2 Remove the four screws from the terminal block access panel on the back panel of the chassis. (See Figure 2-22.)
Figure 2-22 Removing the Terminal Block Access Panel
Step 3 Snap the cable connector of the short DC power cable into the cable strain relief bracket. (See Figure 2-22.)
Step 4 Insert the cable through the left rear of the chassis and connect the leads to the terminal blocks (see Figure 2-23) in the following sequence:
•Black lead to RTNA.
•Red lead to -48A.
Note The ground connections should always be connected first and disconnected last.

Installing and Connecting the 15540-ACPS-N-E External Power Supply
After you have installed the 15540-ACPS-N-E external power shelf in the equipment rack, you can install the external power supplies. If you have not installed the external power shelf, see the "Rack-Mounting the 15540-ACPS-N-E External Power Shelf" section.
To install the 15540-ACPS-N-E power supply, follow these steps:
Step 1 Use a flat blade screwdriver to push in on the release handle latch until the release handle opens. (See Figure 2-26.)
Figure 2-26 Opening the Release Handle
Step 2 With the release handle partially open, place both hands underneath the bottom of the external power supply and carry it to the external power shelf. (See Figure 2-27.)
Figure 2-27 Handling the 15540-ACPS-N-E Power Supply
Caution Use both hands to install and remove the 15540-ACPS-N-E power supply.
Step 3 Slide the 15540-ACPS-N-E power supply all the way into the 15540-ACPS-N-E external power shelf bay until the release handle closes. (See Figure 2-28.)
Note The 15540-ACPS-N-E power supply will not function in the center bay of the 15540-ACPS-N-E external power shelf. Install the blank power supply in the center bay.
Figure 2-28 Installing the 15540-ACPS-N-E Power Supply
Step 4 Ensure that all site power and grounding requirements described in the Regulatory Compliance and Safety Information for the Cisco ONS 15500 Series have been met before you connect the 15540-ACPS-N-E power supply to a power source.
Caution In a system with multiple power supplies, connect each power supply to a separate AC-input power source. In case of a power source failure, the second source is still available.
Step 5 Connect the power cord to the 15540-ACPS-N-E external power shelf. (See Figure 2-29.)
Figure 2-29 Installing the AC Power Cord
Step 6 Verify 15540-ACPS-N-E power supply operation by checking the power supply front panel LEDs:
•AC OK LED is on.
•DC OK LED is on.
Step 7 Check the external power supply status from the system console by entering the show hardware command. For more information on commands, refer to the Cisco ONS 15540 ESP Configuration Guide and Command Reference.
Using Y-Cable
Using an external 2:1 combiner (the y-cable), connections between the client equipment and the transponder interfaces are duplicated. This means each input and output client signal is connected to two transponder interfaces, one active and one standby. During any interval, one of the transmitters at the client interface is turned on and is generating the required optical signal, and the second transmitter is off.
Refer to the Cisco ONS 15540 ESP Planning Guide for y-cable configuration guidelines.
Attaching the Y-Cable
To attach the y-cable to the transponder modules, follow these steps:
Step 1 Read the configuration guidelines in the Cisco ONS 15540 ESP Configuration Guide and Command Reference.
Step 2 Choose which ports you will use.
Step 3 Lift the shutters on the two intended ports and attach one end of the two-sided cable to each of the ports.
Step 4 Attach the other end to the client equipment if not already attached.
