Installation and Setup This chapter contains the following sections: • Static Discharge • Unpacking • Rear Module Options • Board Installation Static Discharge Whenever handling the 9231 and other related equipment, please observe all static discharge precautions as described in the following note: ESD Susceptibility Static discharge can cause serious damage to sensitive semiconductor devices.
Rear Module Installation (Optional) If you are installing the card into a slot with no rear module, you should have ordered and received one of the RM-9231-B modules. You will need to install it in a 20-slot frame before you can connect cables. Use the following steps to install a rear module in the frame: 1. Refer to the frame Owner’s Manual, to ensure that the frame is properly installed according to instructions. 2. On the rear of the frame, locate the card frame slot. 3.
Rear Module Options RM20-9231-B RM20-9231-A/S Figure 2.
Board Installation Use the following procedure to install the 9231 in a 20-slot frame. 1. Refer to the User Manual of the frame to ensure that the frame is properly installed according to instructions. 2. After selecting the desired frame installation slot, hold the 9231 card by the edges and carefully align the card edges with the slots in the frame. Then fully insert the card into the frame until the rear connection plugs are properly seated on the midplane and rear module.
User Controls This chapter contains a description of the 9231 user controls: • LEVEL CONTROLS • LEDs • Jumper Settings • Remote Control . User Controls LEVEL CONTROL SYNCH LED NO SYNCH LED EQ (0 - 300 m) Figure 3. Card-edge User Controls Level The level control is used to adjust the output levels of the 9231. This potentiometers gives precise control of the output signal over a +/-3 dB range EQ(0 – 300m) Provides continuously variable equalization for cable lengths from 0 to 300 metres.
LEDs The front-edge of the card features LEDs that display the status of the input signals. Descriptions are provided in the following table: LED SYNCH NO SYNCH Color Location Display and Description Green Top of the card When illuminated there is a valid analog signal at the input. When illuminated there is not a valid analog signal at the input. Green Second from the top Table 1. Status LED Descriptions Jumper Settings TERM HI Z Selects the input termination, either high impedance or 75 Ohms.
