Ensure the power supply is operating properly by verifying the status indicator LED ➊ (page 1) on the power supply is green. CAUTION Optical input greater than 5 dBm (3.16 VDC measured at OPT PWR TP 1 V/mW testpoint on high gain receiver) may damage the receiver. 2. Verify high gain receiver optical input is within the proper range by measuring DC voltage at the OPT PWR TP 1V/mW testpoint on this receiver based on the position of the optical AGC/TLC mode select switch on the side of the receiver. If level is not within the range specified in the table below, the optical output level from the headend should be adjusted accordingly. 3. Connect signal level meter to RF TP –20dB testpoint on the high gain receiver. Measure the output level at the highest frequency. The minimum high gain receiver RF output level with a 0 dB PAD installed in the RF BALANCING PAD is shown in the following chart. 1508206 Rev A 2 OM2741 Quick Start Guide Opti Max™ OM2741 Quick Start Guide 4. If necessary, adjust the value of the RF BALANCING PAD on the high gain receiver to achieve the RF output level for your optical input and operating mode shown in the chart on page 2 plus 20 dB to compensate for the testpoint loss.

Connect signal level meter to PORT 1 FWD TP testpoint and measure the signal levels at the forward high and low balancing frequencies. The difference in these signal levels is the measured tilt. 2. The system tilt is the desired tilt and should be provided on the system map or by your manager. ■ 3. System Tilt – Measured Tilt = Equalization Difference If Equalization Difference is positive, add this value to the EQ installed at PORT 1 FWD EQ for new EQ value If Equalization Difference is negative, subtract this value from the EQ installed at PORT 1 FWD EQ for new EQ value Repeat Steps 1 and 2 to equalize the remaining ports. 1508206 Rev A 3 OM2741 Quick Start Guide Opti Max™ OM2741 Quick Start Guide Attenuating Forward RF Signal 1. Connect signal level meter to PORT 1 FWD TP testpoint and measure the signal level at the forward high balancing frequency, compensating for the 20 dB testpoint loss. 2. Attenuate the port RF output level to obtain the system design RF output level. ■ 3. Measured Fwd High Balancing Level (TP comp. add 20) – System Fwd High Balancing Level = PORT 1 FWD PAD Value Repeat Steps 1 and 2 to attenuate the remaining ports.

Ensure the following conditions have been met for the RF module of the OM2741: ■ The system map is marked with node output levels for bandedge frequencies. ■ Ends of feeder cables and unused active RF ports are terminated with a 75  impedance; all tap outlets are terminated with dust caps. ■ All amplifiers preceding the Opti Max2741 in the return path have been set up to provide the correct Return Port Input Levels. ■ 75  terminators have been removed and NPB-000s have been installed in REV PAD locations of all return ports. Ensure that the following conditions have been met for the optical lid of the Opti Max2741: ■ The power supply has been installed, and operating voltages (24 VDC, 12 VDC, and 5 VDC) are correct. ■ The optical modules, return configuration module, and appropriate accessories have been installed. Refer to Physical Identification on page 1 for proper return transmitter installation location. ■ 0 dB NPB PADs have been installed in all analog return transmitter CONFIG PAD/RF BALANCING PAD locations or the return configuration selector switch on the digital processing module is set to the R4x1 position: Note DWDM analog transmitters and DWDM SFPs are shipped separately for Opti Max2741s ordered with these return configurations, but the correct number of NPB series PADs at the correct value for the return configuration designated at the time of ordering is included in the node. To ensure that CWDM and DWDM transmitters are configured properly, install these PADs into the transmitter CONFIG PAD locations prior to return setup. 3. Clean the optical output fibers according to your company’s procedures or refer to the ARRIS Fiber Care and Cleaning Guide, P/N 1506507, and connect them to the appropriate return transmitters. 4. Connect a multimeter to the analog return transmitter OPT PWR TP testpoint. If the multimeter reading is not within the 1.8 to 2.2 VDC range, troubleshoot the node. Return Balancing the Node 1. Connect a signal generator to PORT 2 FWD TP testpoint on the RF module. 2. Set signal generator to the system design level + 20 dB to account for the signal injection loss through the 20 dB testpoint. If the system design level is not specified, ARRIS recommends injecting 32 dBmV/channel. This is equivalent to 12 dBmV/channel at the port + 20 dB to compensate for the 20 dB testpoint loss. 3. Connect a signal level meter to either the associated analog return transmitter monitor (0 dB) testpoint or to the digital return processing module’s RF input (–20 dB) testpoint. The recommended level at the return Tx testpoint is listed in Table 1. If necessary, replace the corresponding PORT x REV PAD to achieve this level. 4. Repeat Steps 1 through 3 for the other active ports. 1508206 Rev A 5 OM2741 Quick Start Guide Opti Max™ OM2741 Quick Start Guide Table 1 Recommended Transmitter Testpoint Level Configuration Analog Return Tx Factory-installed CONFIG PAD/RF BALANCING PAD Return Configuration Selector Switch Setting on Digital Return Processing Module Recommended Level at Analog Return Tx Monitor Testpoint Recommended Level at Digital Return Processing Module Testpoint Redundant 4 x 1 0 R4x1 12dBmV –8dBmV 4x1 0 R4x1 12dBmV –8dBmV 2x2 0 R4x1 12dBmV –8dBmV Switching from Redundant 4x1 to non-redundant 4 4x1 R2x2 12dBmV –8dBmV 1508206 Rev A 6 OM2741 Quick Start Guide Opti Max™ OM2741 Quick Start Guide Figure 2 Digital Return Path Functional Block Diagram Port 3 5 to 42MHz or 5 to 65MHz Digital Return 75 W PORT 2 FWD TP PORT 2 REV TP * * * Return Switch Return Switch AC Power to Power Supply AC RF PORT 4 REV PAD PORT 2 REV PAD H L RF AC LPF PORT 4 FWD TP * * RF AC H L PORT 5 REV TP PORT 5 FWD TP * * LPF PORT 6 REV PAD Return Switch 2x2 Segmentation Switch Network PORT 3 REV TP PORT 3 FWD TP PORT 4 REV TP AC Power to Power Supply PORT 3 REV PAD H L * Port 2 RF AC 1x4 Return Switch 2x2 H L * PORT 6 REV TP 2x2 Port 4 RF AC Port 5 AC RF Port 6 * Port 1 PORT 6 FWD TP 1x4 Base Lid ** 1x4 and 2x2 Non-Redundant Configurations (AUX 1) DC Power to Lid and RF Module REV EMS (AUX 2) Ch.

The Mil Spec Hdbk 217 states that a 9°C increase in device operating environments will reduce the product’s reliability (and projected lifetime) by 50%. Therefore, you should take proper care to maximize airflow around the OM2741 and to minimize ambient temperatures, especially if you will be installing the OM2741 in an enclosed environment (e.g. pedestal, cabinet, etc.).
