Safety Recommendations

General Safety Practices

Follow these guidelines to ensure personal safety and protect the equipment:

Maintaining Safety with Electricity

Follow these guidelines when working on equipment powered by electricity.

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.
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 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 can weld the metal object to the terminals.
Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use.
Warning When installing the unit, the ground connection must always be made first and disconnected last.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic components are improperly handled and can result in complete or intermittent failures.

Always follow ESD-prevention procedures when removing and replacing components. Ensure that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to the ESD-strap connection jack (to the left of the power switch on the rear of the chassis) or to an unpainted chassis frame surface. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. 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 megohm (Mohm).

Keeping Track

Cisco recommends that you use an installation checklist and maintain a Site Log.

Step 1   Attach the brackets as shown in Figure 3-11.


Figure 3-11: Attaching the Wall-Mount Brackets


Step 2   Attach the chassis assembly to the wall as shown in Figure 3-12, using screws and anchors that you provide. Cisco recommends the following:

Caution To prevent the chassis from pulling away from the wall, align the brackets and screws with a vertical wall stud. (See Figure 3-12.) To ensure adequate ventilation, make sure there is clearance between the chassis and the wall. The rubber feet provide clearance.


Figure 3-12: Wall-Mounting the Chassis


Installing the Ground Connection

If your Cisco MC3810 chassis uses AC power or a Cisco Redundant Power System (RPS), you must ground the chassis to an approved ground using an AWG 6 ground wire and the grounding lug included in the accessory kit. To install the ground wire, complete the following steps:

Note   The NEBS Level 3/ETSI compliance kit provides chassis grounding, if installed.
Step 1   Strip one end of the AWG 6 ground wire to expose approximately 0.75 inch (20 mm) of conductor.

Step 2   Crimp the grounding lug onto the ground wire. (See Figure 3-13.)


Figure 3-13: Crimping the Ground Lug onto the Ground Wire


Step 3   Attach the grounding lug to the two ground terminals on the rear of the Cisco MC3810 chassis using the two nuts with lockwashers provided
(M4 X 0.7 thread with 7 mm outer diameter). (See Figure 3-14.)

Note   You can orient the crimped end of the grounding lug in either direction (right or left).

Step 4   Connect the other end of the ground wire to a grounding point at your site.


Figure 3-14: Grounding Lug Fastened to Terminals


Connecting the Input Power

Your Cisco MC3810 series concentrator may be equipped with an internal AC power supply or DC power supply, or it may be set up to use power from a Cisco Redundant Power System (RPS). Connect the appropriate power for your installation as follows.

Note   The installation must comply with all applicable codes.

AC Power Connection

If your Cisco MC3810 series concentrator uses AC power, connect the AC power cable (supplied) to the recessed power plug on the rear of the concentrator, and plug the cable into a power source with a voltage of 100 to 240 VAC. Figure 3-15 shows the rear of an AC-powered Cisco MC3810.

Wiring the DC-Input Power Supply

Warning This unit is intended for installation in restricted access areas. A restricted access area is where access can only be gained by service personnel through the use of a special tool, lock and key, or other means by security, and is controlled by the authority responsible for the location.
Warning Before conducting 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.
Step 1   Note the orientation of the DC power supply. The power cord should have three copper wires: + (positive), - (negative), and a safety ground.

Figure 3-17 shows the DC terminal block and the locations of the ground, positive, and negative terminals.

Warning  The illustration shows the DC power supply terminal block. Wire the DC power supply using the appropriate wiring terminations at the wiring end, as illustrated. The proper wiring sequence is ground to ground, positive to positive, and negative to negative. Note that the ground wire should always be connected first and disconnected last.

Step 2   Strip 0.25 inch (63 mm) of insulation from the safety ground, the positive wire, and the negative wire.

Caution Do not overtorque the terminal block contact screws. The recommended torque is 8.2 ± 0.4 inch-lb (0.93 ± 0.01 N·m).

Step 3   Connect the safety ground to the ground terminal, and tighten the screw. Make sure that no bare wire is exposed.

Step 4   Connect the positive wire to the + (positive) terminal, and tighten the screw. Make sure that no bare wire is exposed.

Step 5   Connect the negative wire to the - (negative) terminal, and tighten the screw. Make sure that no bare wire is exposed.

Step 6   Position the wires as shown in Figure 3-17 and attach them to the plastic strain-relief bracket with two cable ties (included).

Caution The wires must be secured so that they will not be disturbed by casual contact. For example, secure the wires to a rack frame using cable ties.

Step 7   Remove the tape from the circuit breaker switch handle and restore power by moving the circuit breaker handle to the ON position.

Warning After wiring the DC power supply, remove the tape from the circuit breaker handle and reinstate power by moving the handle of the circuit breaker to the ON position.

Cisco Redundant Power System Connection

If your Cisco MC3810 series concentrator is equipped to receive its power from a Cisco Redundant Power System (RPS), you first need to install the Cisco RPS. See the Cisco Redundant Power System Hardware Installation Guide for detailed instructions.

Warning Use the Cisco RPS (model PWR600-AC-RPS) only to power the external device.

Figure 3-18 shows the rear of a Cisco MC3810 equipped for use with a Cisco RPS.


Figure 3-18: Cisco MC3810 Using Cisco Redundant Power System--Rear View


Quasi-Redundant Power Configuration

The Cisco RPS can provide quasi-redundant power for up to four Cisco MC3810 concentrators. This configuration, shown in Figure 3-19, uses two parallel AC-input power modules to supply the Cisco RPS, but only one DC output power module for each Cisco MC3810 series concentrator. The AC input is fully redundant, but the DC output is not redundant. The quasi-redundant configuration requires a separate one-to-one power cable for each Cisco MC3810 series concentrator.


Figure 3-19: Quasi-Redundant Power Configuration


Fully Redundant Power Configuration

The Cisco RPS can provide fully redundant power for up to two Cisco MC3810 series concentrators. In this configuration, shown in Figure 3-20, two parallel AC-input power modules supply the Cisco RPS, and two parallel DC output power modules supply each Cisco MC3810. The AC input and DC output are both fully redundant. The fully redundant configuration requires a two-to-one (Y) power cable for each Cisco MC3810.


Figure 3-20: Fully Redundant Power Configuration


Cisco RPS Connection Procedure

Follow these steps to connect the Cisco MC3810 series concentrator to the Cisco RPS.

Note   Use the appropriate Cisco RPS output cables: 1-to-1 for quasi-redundant or 2-to-1 for fully redundant. You can mix 1 fully redundant and 1 or 2 quasi-redundant power feeds. See the Cisco RPS Hardware Installation Guide for cable ordering information.
Step 1   Turn OFF the power switch on the rear of the Cisco MC3810.

Step 2   Plug the 22-pin connector(s) into the Cisco RPS, and tighten the thumbscrews.

Step 3   Plug the eight-pin connector into the eight-pin power receptacle on the rear of the Cisco MC3810, and tighten the thumbscrews. Note that the power receptacle is slightly recessed within the Cisco MC3810 chassis.

Note   If your Cisco MC3810 is powered by a Cisco RPS, there is a 10-second delay after you turn the power switch ON, before power is supplied from the Cisco RPS.
