Warning Infra-red laser energy may be present on the cable connected to the receiving (input) connector. The transmitting (output) optical fiber connector and the monitoring (output monitor) connector are equipped with shutters that automatically close when a cable is removed. To avoid potential damage to the eyes, do not look directly into an optical fiber cable or a connector (whether shuttered or not). When an optical cable is not attached, place the supplied protective cap over the cable's connector. The output monitor output connector should be capped when not in use. |
|
Warning Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not view directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard. |
|
Warning Use of controls, adjustments, or performing procedures other than those specified may result in hazardous radiation exposure. |
To connect the customer-supplied optical fiber cable to the SC/UPC optical ports, follow these steps:
Step 2 Connect the output optical fiber cable to the output connector (see Figure 2-2 and Figure 2-3). Avoid making sharp bends in the cable.
The Cisco ONS 15501 AC can be powered directly from the facility VAC input through the Cisco ONS 15501 120-240 VAC power supply. This section describes how to connect AC power to the chassis.
|
Caution Check the power at your site to ensure that you are receiving clean power (free of spikes and noise). Install a power conditioner, if necessary, to ensure proper voltages and power levels in the source voltage. |
|
Caution Use only the hardware provided with the Cisco ONS 15501. Failure to use the provided hardware may result in unintended damage. If hardware is lost, contact Cisco Systems for a replacement. |
 |
Note The AC power cord that connects to the Cisco ONS 15501 120-240 VAC power supply power cord and then to the building VAC is not shipped with the Cisco ONS 15501. You must order this power cord separately. |
There are six styles of AC-input power supply power cords available (differing in plug type); make sure you have the correct style for your site (see Figure 2-4). All AC-input power supply power cords measure 8 feet (2.5 m). We recommend that you do the following:
Table 2-1 lists the AC power cord options.
Table 2-2 lists the nominal and acceptable value ranges for source AC power.
To connect the provided grounding lug to the tapped frame grounding holes, follow these steps:
Step 2 Identify the two tapped frame grounding holes at the upper right side of the Cisco ONS 15501 AC front panel. (See Figure 2-2.)
Step 3 Remove the two screws provided for securing the ground lug to the Cisco ONS 15501 AC.
Step 4 Connect the 8 AWG grounding wire to the grounding lug. The other end of the wire should be suitably grounded.
Step 5 Install the grounding lug on the Cisco ONS 15501 AC, using the two provided screws and washers.
Step 6 Test for proper frame ground using the ohmmeter section of a digital voltmeter. Place one prod on the Cisco ONS 15501 AC and the other on the frame grounding bus to which the grounding lug and grounding wire is connected. Observe for a zero-resistance ground.
The section describe how to ground the Cisco ONS 15501 DC and connect DC power to it.
