C H A P T E R 3 Installing the Chassis This chapter describes how to install and test the Cisco Metro 1500 series system chassis. The equipment is installed during normal working hours. It is usually connected to active CPU channels or control units after working hours.
Chapter 3 Installing the Chassis Before Installing Caution Use extreme care when removing or installing connectors so you do not damage the connector housing or scratch the end-face surface of the fiber. Always install protective covers on unused or disconnected components to prevent contamination. Always clean fiber connectors before installing them.
Chapter 3 Installing the Chassis Before Installing Upon receipt, inspect the equipment as follows: Step 1 Take inventory. Compare the equipment inside with the packing slip and the equipment list provided by customer service. If there are any discrepancies, notify the Customer Service Center. Step 2 Check for external damage. Visually check all components and immediately report any shipping damage to your customer service representative.
Chapter 3 Installing the Chassis Installing the System Caution Because of rack mounting, the plugs of the power cables on the rear side of the unit might not be accessible. Please provide a power circuit breaker to allow front power access. If you do not use a power circuit breaker, ensure quick access to the plug-socket combinations on the rear side of the unit at all times. In this case they serve as the main means of disconnecting.

Chapter 3 Installing the Chassis Cleaning the System Table 3-1 lists the power requirements in different countries. Table 3-1 Power Requirements Region Power Requirements North America 110 to 120 VAC, 60 Hz or -48 to -60 VDC Europe 210 to 240 VAC, 50 Hz or -48 to -60 VDC Grounding the Chassis Connecting the power cords to the chassis provides basic grounding. You should also connect a separate grounding cable for each chassis to the rack.
Chapter 3 Installing the Chassis Cleaning the System Cleaning the Chassis Be very careful with the air flow system when you clean the chassis. If the cleaning process has to be done while the system is on, be aware that the airflow system is in operation. Clean the chassis with a damp cloth only and be careful of the following: • Do not touch the safety lattice of the airflow system while fans are operating. • Do not use wet tissues for cleaning the product's outer housing.
Chapter 3 Installing the Chassis Cleaning the System Before installing any type of cable or connector, use a lint-free alcohol pad from a cleaning kit to clean the ferrule, the protective white tube around the fiber, and the end-face surface of the fiber. As a general rule, whenever there is a significant, unexplained loss of light, clean the connectors.
Chapter 3 Installing the Chassis Removing the Power Supply Module Note • Cover the connector adapters to avoid soiling or contaminating the inside of the adapters while cleaning the chassis. • Cover the connectors and adapters to avoid the inside of the adapters or the surface of the connectors from getting dirty when not using the connectors. If the surface is not clean or does not have a uniform shine, repeat the process using a fresh surface of the alcohol pad.
Chapter 3 Installing the Chassis Removing the Power Supply Module The display on the front panel of the chassis indicates whether the power is on or off. You can also monitor power status from the NEMI. For more information about monitoring the power supply from the NEMI, refer to the Cisco Metro 1500 series Software Configuration Guide.
Chapter 3 Installing the Chassis Removing the Power Supply Module Determining Power Supply Status If the LED on a power supply is off while the unit is powered on, and the power cable is plugged in the corresponding power socket, then either the cable is faulty, a fuse has blown, or the power supply itself has failed. To determine the possible cause of the failure, follow these steps: Step 1 Check the power cable to make sure that it is securely plugged into the unit.

Chapter 3 Installing the Chassis Running Online Tests Running Online Tests Note The power levels cannot be checked without special measurement equipment because of the automatic laser shutdown (ALS). All power measurements must be done in-line because of ALS. System checkout and online testing are usually performed during working hours. Be sure to coordinate these tasks with the Cisco authorized representative.
Chapter 3 Installing the Chassis Running Online Tests Measuring Channel Outputs and Channel Budgets Channel module outputs, measured at entry to the MUX, point B, or exit of the DMX, point E, are practically constant for all channel cards, whereas measurements at the exit of the BSM (point C) or entry to the BSM (point D) can exhibit a variation of 0 to 2 dB. Note All power measurements must be done in-line because of ALS. All measurements concerning budgets need modulated light.
Chapter 3 Installing the Chassis Running Online Tests Step 3 Use the ocmstate command to switch on the local loop. Now you can measure the output power at point F. Afterwards, switch off the local loop. To measure at points B or C, follow Steps 1 and 2 and then Step 4: Step 4 Use the ocmstate command to switch the remote laser to “forced ON” to overcome ALS. Then measure at points B and C. If you want to measure the input at points D or E, follow Steps 1, 2, and 3 and then Step 5.
