Required Tools and Equipment

You need the following tools and equipment to remove and install SPE and MRP cards:

Number 1 Phillips screwdriver

ESD-prevention equipment or the disposable ESD-preventive wrist strap included in the hardware accessory kit

Antistatic mat, foam pad, or bag for removed cards (place removed components into an antistatic bag if you plan to return them to the factory; or place them on an antistatic mat or foam pad if you are replacing components)

Safety Precautions and Maintenance Guidelines

This section provides guidelines that you should follow when working on the Cisco ICS 7750.

General Safety Precautions

Read the warnings in this section before working on the system.


Warning Read the installation instructions before you connect the system to its power source.



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



Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 16A international) is used on the phase conductors (all current-carrying conductors).



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



Warning Only trained and qualified personnel should be allowed to install or replace this equipment.



Warning The device is designed to work with TN power systems.



Warning SPE cards contain a lithium battery. There is the danger of explosion if the battery is replaced incorrectly. Replace the battery only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions.


ESD Safety Precautions

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD occurs when electronic printed circuit cards are improperly handled. ESD can result in complete or intermittent failures. Always follow ESD-prevention procedures when removing and replacing cards and other system 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 an unpainted surface of the chassis frame to safely channel ESD voltages to ground.

To properly guard against ESD damage and shocks, the wrist strap 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 (Mohms).


Caution Static voltages as low as 30 volts can cause latent damage to circuitry. Be sure to observe all standard antistatic procedures (for example, wear a grounding strap) when handling electronic equipment and components.


Warning Blank faceplates (filler panels) serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards and faceplates are in place.


Safety with Electricity


Note The following guidelines are IMPORTANT SAFETY INSTRUCTIONS.


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.

Disconnect all power before installing or removing a Cisco ICS 7750 chassis.

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 chassis.

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

Determine whether the victim needs rescue breathing or external cardiac compressions; then take appropriate action.


Note SAVE THESE INSTRUCTIONS.


Telephone Wiring Guidelines

Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:

Never install telephone wiring during a lightning storm.

Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

Hot Swapping Cards

You can hot swap cards while the Cisco ICS 7750 is operating. With hot swapping, you do not need to power down the system.


Warning Only trained and qualified personnel should be allowed to install or replace this equipment.



Caution You can install only one system alarm processor (SAP) and one system switch processor (SSP) card in a single Cisco ICS 7750 chassis. If you must hot swap the SAP, the cooling fans do not operate, and the system's ability to detect alarms associated with the operating environment, fans, and power supply modules is degraded until an operational SAP is properly reinserted in the chassis. If you must hot swap the SSP, the system loses LAN connectivity, and calls being made from or to Cisco IP Phones that are routed through that SSP are disconnected until an operational SSP is properly reinserted in the chassis.


Note Depending on your system configuration, hot swapping SPEs, ASIs, or MRPs can adversely affect users connected to the system. For example, if Cisco CallManager is running on only one SPE, hot swapping that SPE disconnects calls to or from the Public Switched Telephone Network (PSTN) and prevents the system from processing further PSTN traffic until an operational SPE is properly reinserted in the chassis. Similarly, hot swapping an MRP that is in the process of routing voice or WAN traffic prevents that traffic from reaching its destination. Contact your Cisco sales representative for guidelines on installing cards and software on your system for maximum availability and redundancy.


Card and Module Replacement Guidelines

The following are examples of recommended practices for inserting system cards:

Do not force the faceplate into its slot. This action can damage the pins on the backplane if they are not aligned properly with the module or card.

Fully depress the ejector levers to ensure that the card or module connector mates with the backplane correctly. The card or module should be firmly seated in the slot. Any card that is only partially connected to the backplane can disrupt system operation.

Use the installation screws (at the top and bottom of the card) to secure the card firmly in place in the chassis.

Removing Cards

For card removal instructions, refer to Cisco ICS 7750 FRU Installation and Replacement.


Note Do not press the SHTDN button on any card other than the SPE card.


Locating Modules

This section shows you how to locate the DIMM and PVDM slots on SPE310, MRP200, ASI81, ASI160, MRP300, MRP3-8FXS, and MRP3-16FXS cards, and the SIMM (Flash memory) slots on the MRP300, MRP3-8FXS, and MRP3-16FXS cards.

Removing and Installing Modules

This section explains how to remove and install modules.


Warning When performing the procedures in this section, wear grounding wrist straps to avoid ESD damage to the Cisco ICS 7750. Do not directly touch the backplane with your hand or any metal tool, to prevent personal injury or equipment damage.


Removing and Installing DIMMs

This section explains how to remove and install DIMMs.

DIMM Orientation

DIMMs are manufactured with polarization notches to ensure proper orientation and with alignment holes to ensure proper positioning. Figure 4 shows the notches and holes on a DIMM. DIMMs are installed with the connector edge down.


Caution To avoid damaging ESD-sensitive components, observe all ESD precautions. To avoid damaging the underlying board, do not use excessive force when you remove or replace DIMMs.

Figure 4 DIMM Orientation Aids

Removing a DIMM from an SPE Card

Complete the following steps to remove a DIMM from an SPE310.


Step 1 Attach an ESD-preventive wrist strap, and ensure that it makes good contact with your skin. Connect the equipment end of the wrist strap to the metal back plate of the chassis, avoiding contact with the connectors.

Step 2 Locate the DIMM slots on the SPE. See Figure 1.


Caution Handle DIMMs by the edges only. DIMMs are ESD-sensitive components, and they can be damaged by mishandling.
