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.


Safety with Electricity


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:

Locate the room's emergency power-OFF switch. Then, if an electrical accident occurs, you can quickly shut the power OFF.

Before working on the system, turn OFF the power and unplug the power cord.

Disconnect all power before doing the following:

Working on or near power supplies

Installing or removing a router chassis or network processor module

Performing a hardware upgrade

Do not work alone if potentially hazardous conditions exist.

Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds.

Never assume that power is disconnected from a circuit. Always check.

If an electrical accident occurs, proceed as follows:

Use caution, and do not become a victim yourself.

Turn OFF power to the system.

If possible, send another person to get medical aid. Otherwise, determine the condition of the victim and call for help.

Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

Preventing Electrostatic Discharge Damage

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.


Cisco ONS 15304 Distribution Panel Components

The Cisco ONS 15304 distribution panel is used to break out individual E1 and Ethernet ports from the Cisco ONS 15304. The distribution panel is shown in .

Figure 1 Cisco ONS 15304 Distribution Panel

The distribution panel has the following components:

One 50-pin telco G.703 E1 port—Connect the distribution panel to the 50-pin telco G.703 E1 port on the Cisco ONS 15304.

One 50-pin telco Ethernet port—Connect the distribution panel to the 50-pin telco Ethernet port on the Cisco ONS 15304.

Two tributary monitoring ports (labeled IN and OUT)—Connect test equipment to the Cisco ONS 15304 distribution panel. All eight G.703 E1 input pairs are wired to the tributary monitoring port labeled IN. All eight G.703 E1output pairs are wired to the tributary monitoring port labeled OUT.

Eight G.703 E1 ports—Connect the distribution panel to individual G.703 E1 devices.

Two external synchronization clock ports (labeled A and B)—Connect an external synchronization reference. Each port can take a referenced input, and each port also provides a timing reference output. Ports A and B are duplicated references; their values are always identical.

Eight RJ-45 Ethernet ports—Connect the distribution panel to individual Ethernet devices.

Fiber management tray—Manage the layout of fiber-optic wiring within the distribution panel. The optical fibers connect to the Cisco ONS 15304.

Two grounding studs—Ground the Cisco ONS 15304 distribution panel.

Two cable access holes—Route cables into and out of the distribution panel.

Two rack ears—Mount the Cisco ONS 15304 distribution panel in a standard 450-mm or 500-mm rack.

Grounding the Cisco ONS 15304 Distribution Panel


Warning   

This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use.



Warning   

Connect to a -48/60 VDC source that is electrically isolated from an AC source and is reliably connected to earth.



Warning   

Care must be given to connecting units to the supply circuit so that wiring is not overloaded.


To ground the Cisco ONS 15304 distribution panel, you need:

One number 18 AWG wire (not included).

One standard barrel two-hole copper wire number 8 AWG (not included). Panduit number LCD8-10A-L (strip length 9/16-inch) lug or equivalent.

Two number 10-32 screws with green captive saw-toothed washer (included).

Before you install any modules or attach cables or connectors, ground the Cisco ONS 15304 distribution panel chassis.


Note   Grounding requirements are less than or equal to 25 ohms.



Warning   

Operating ungrounded electrical equipment can result in severe electrical shock and damage the equipment.



Step 1 Find the grounding screw holes on the front of the Cisco ONS 15304 distribution panel. (See .)

Step 2 Secure the ground wire to the standard barrel two-hole lug.

Step 3 Fasten the wire and lug to the distribution panel with the two green number 10-32 screws from the accessory kit.

Step 4 Connect the other end of the copper wire to earth ground.
