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.



Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Both LAN and WAN ports may use RJ-45 connectors. Use caution when connecting cables.



Warning Hazardous network voltages are present in WAN ports regardless of whether power to the router is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the router first.



Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages.



Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.



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.


The following warning applies in Australia:


Warning The telecommunications lines must be disconnected 1) before unplugging the main power connector and/or 2) while the housing is open.


Follow these guidelines when working on equipment powered by electricity:

Locate the emergency power-off switch in the room in which you are working. Then, if an electrical accident occurs, you can quickly shut the power OFF.

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

Disconnect all power before doing the following:

Installing or removing a router chassis

Working near power supplies

Do not work alone if potentially hazardous conditions exist.

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

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

If an electrical accident occurs, proceed as follows:

Use caution; do not become a victim yourself.

Turn OFF power to the router.

If possible, send another person to get medical aid. Otherwise, determine the condition of the victim and then 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 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 megohms (Mohm).

Required Tools and Equipment

You need the following equipment to perform all procedures described in this document:

ESD-preventive wrist strap

Nonmagnetic number 1 Phillips screwdriver or small flat-blade screwdriver


Tip Use the ESD bag in which the network module was shipped to prevent electrostatic damage from a charged surface.


Installing an Expansion Module

To install an expansion module, use the following procedure:


Step 1 Remove the network module from the router chassis (refer to the Cisco Network Modules Hardware Installation Guide).

Step 2 Place the network module on an ESD-protected surface.


Caution Minimize contact with the bottom of the network module to avoid damage to components located on the bottom of the card.

Step 3 (optional) Remove the current expansion module, using the procedure listed in the "Removing an Expansion Module" section.

Step 4 Using a Phillips screwdriver, remove the left faceplate screw from the connector outlet cover plate (see Figure 1).

Figure 1 Cisco CE Network Module for Caching and Content Delivery Faceplate


Note Some early Cisco CE network modules have an inactive USB port on the faceplate. This USB port has been removed in later Cisco CE network modules.


Step 5 Using a nonmagnetic Phillips screwdriver, remove the right faceplate screw next to the SCSI connector outlet and the two screws from their standoffs on the network module (see Figure 1 and Figure 2).

Step 6 Align the expansion module with the standoffs on the network module, then press downward to engage the connector (see Figure 2).


Caution Use gentle pressure when removing or installing an expansion module. Excessive force can damage connector pins or other board components.


Tip Confirm the SCSI connector on the EM-CE-SCSI is inserted through the SCSI connector outlet on the network module faceplate before pressing downward on the expansion module.
