 | Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. |
| Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord. |
The following warning applies to routers with a DC power supply:
| Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. |
| Warning Ultimate disposal of this product should be handled according to all national laws and regulations. |
 | Caution To avoid damaging electrostatic discharge (ESD)-sensitive components, ensure that you have discharged all static electricity from your body before opening the chassis. |
| Warning The Ethernet 10BaseT, serial, console, and auxiliary ports contain safety extra-low voltage (SELV) circuits. BRI circuits are treated like telephone-network voltage (TNV) circuits. Avoid connecting SELV circuits to TNV circuits. |
| Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. |
Follow these guidelines when working on equipment powered by electricity:
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that the router chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist strap and cord must be used correctly. If no wrist strap is available, ground yourself by touching the metal part of the chassis.
| Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohms (Mohm). |
| Caution Before opening the chassis, be sure that you have discharged all static electricity from your body and the power is OFF. |
| Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. |
This section describes how to insert a SONET Access Module (SAM) in a new chassis. You might need to insert a SAM (or SAMs) in a new chassis because your current chassis is not working.
| Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is OFF and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. |
You will need the following tools and parts to replace a chassis:
To replace the chassis:
Step 1 Attach an ESD-preventive wrist strap to your wrist.
Step 2 Turn the chassis power OFF.
Step 3 Remove the plastic shield on the terminal block with a number 2 Phillips screwdriver. See Figure 3 and Figure 4 for the location of the terminal block.
Step 4 Detach the -48 VDC (red wire) and -48 VRTN (black wire) from the 48V A and B feeds on the terminal block.
Step 5 Remove the SAM from the old chassis by loosening the ejectors on the SAM with your fingers or a number 2 Phillips screwdriver and pulling the SAM toward you. Repeat this step to install more than one SAM in a redundant system.
Step 6 Loosen the screw on the fan tray with your fingers or a number 2 Phillips screwdriver and remove the fan tray by pulling it toward you.
Step 7 Unscrew the fuse cover with a flat-head screwdriver to remove the fuse.
Step 8 Disconnect all cables from the old chassis.
Step 9 Ground the new chassis.
| Warning Operating ungrounded electrical equipment can result in severe electrical shock and damage the equipment. |
Step 10 Find the grounding screw holes on the front of the system. See Figure 1 for the location of the grounding studs for the Cisco ONS 15304. See Figure 2 for the location of the grounding studs for the Cisco ONS 15303.
Step 11 Secure the ground wire to the standard barrel 2-hole lug.
Step 12 Fasten the wire and lug to the system with two number 10-32 screws (green).
Step 13 Connect the other end of the copper wire to earth ground.
Step 14 Make sure the power is switched off at the power supply before connecting the power feeds to the new chassis.
Step 15 Attach the -48 VDC (red wire) and -48 VRTN (black wire) to the 48V A and B feeds (number 18 AWG minimum) to the terminal block. See Figure 3 for the location of the terminal block on the Cisco ONS 15304. See Figure 4 for the location of the terminal block on the Cisco ONS 15303.
Step 16 Reattach the plastic shield on the terminal block with the number 2 Phillips screwdriver.
Step 17 Connect the other end of the power cord to the power source.
Step 18 Turn the power ON at the power supply and verify that the voltages are 48V for both A and B feeds.
Step 19 After verifying the voltages, grasp the SAM to be inserted by the ejectors and insert it in the chassis. Tighten the screws on the ejectors with your fingers. Repeat this step to install more than one SAM in a redundant system.
Step 20 Connect all cables.
Step 21 Replace the fan tray by sliding it into the vacant fan tray slot until it is firmly seated in the chassis.
Step 22 Tighten the screw on the fan tray with a number 2 Phillips screwdriver.
Step 23 Replace the fuse by screwing it into the chassis with a flat-head screwdriver.
Step 24 If you removed both SAMs from the old chassis and inserted them in the new chassis, you will see the following example error message:
The following Chassis serial number stored on board: PIP980201150000 does not match current chassis serial: Awaiting synchronization or ine copy sys command
Step 25 At the Cisco ONS 15303 prompt or the ONS 15304 prompt, enter:
conf t
Step 26 Enter:
ine copy sys-id sam a or ine copy sys-id sam b
Step 27 Enter:
sam a or sam b
depending on which one is the active SAM. The active SAM is indicated by a green active LED on the front of the SAM. Entering this command causes the active SAM to copy the system-id to itself.
