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.


Note The following guidelines are IMPORTANT SAFETY INSTRUCTIONS.


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

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.

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.

Use caution when installing or modifying telephone lines.

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

Use caution when installing or modifying telephone lines.

Ground Conductor Warning

Warning Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

Note The number of channels per DSP that can be supported on the MRP cards depends on the codec complexity configured and on the DSP image being used on an individual VIC. For additional information, refer to the "Choosing DSP Firmware" section in Chapter 6, "Configuring the Cisco ICS 7750," in the Cisco ICS 7750 Installation and Configuration Guide.



Note The MRP200 and MRP300 cards are both voice-and-data-capable routers that support digital and analog voice trunks and WAN routing interfaces to link remote Ethernet LANs to the public switched telephone network (PSTN), to existing private branch exchanges (PBXs), and to most common analog devices, such as fax machines and teleconferencing stations. The MRP300 family of cards (MRP300, MRP3-8FXS, MRP3-16FXS, and MRP3-8FXOM1) has additional functionality provided by Flash memory.

Configuration files for the MRP200 are loaded and saved to the SPE running System Manager, whereas configuration files and the Cisco IOS image for the Flash-based MRPs are loaded and saved on each MRP in nonvolatile RAM (NVRAM). This allows for a faster boot-up process on the Flash-based MRPs, and it enables these cards to be functional before the SPE is fully operational.


Modules for MRP300 Cards

The MRP300 ships with 64 MB of onboard RAM and can support 64 MB of add-on memory. You can install the following types of modules in an MRP300:

DIMM. The MRP300 has one DIMM slot for upgrading MRP memory. Installing a DIMM increases the DRAM of the MRP300. The maximum amount of RAM that is supported on the MRP300 is 128 MB.

PVDMs. The MRP300 has two PVDM slots. Installing or replacing a PVDM gives the MRP300 additional DSPs for processing heavier voice traffic loads. (Refer to Chapter 6, "Configuring the Cisco ICS 7750," in the Cisco ICS 7750 Installation and Configuration Guide for additional information about DSP resources on MRP cards.)

VPN module. The MRP300 has a socket for a VPN module. Installing a VPN module gives the MRP300 the ability to encrypt data using the DES and 3DES algorithms at speeds suitable for a full-duplex T1 serial connection (4 megabits per second [Mbps] for 1514-byte packets).

Single in-line memory module (SIMM). The MRP300 has one SIMM Flash memory module slot. The MRP300 has 16 MB of onboard Flash memory, and it has a SIMM slot for increasing the Flash memory up to 80 MB by adding 16-MB, 32-MB, or 64-MB SIMMs.

Modules for MRP3-8FXS, MRP3-16FXS, and MRP3-8FXOM1 Cards

The MRP3-8FXS, MRP3-16FXS, and MRP3-8FXOM1 cards are all Flash-based MRPs. Configuration files for the MRP3-8FXS, MRP3-16FXS, and MRP3-8FXOM1 cards are loaded and saved on each card in NVRAM.

The MRP3-8FXS and MRP3-16FXS cards are ASI cards with Flash memory.

The MRP3-8FXS can support eight connections to analog telephones, fax machines, and teleconferencing stations.

The MRP3-16FXS card can support 16 connections.

The MRP3-8FXOM1 is supported only in M1-compliant countries, such as the US. It includes eight built-in Foreign Exchange Office (FXO) M1 analog interfaces to enable connection of eight analog trunks between a central office (CO) and an IP telephony system. Like the MRP3-8FXS, the MRP3-8FXOM1 also includes an open VWIC slot (slot 1) that accepts all Cisco ICS 7750-supported VWICs.

The ICS System Software release that supports the MRP3-8FXOM1 also includes the capability for DSP resources in PVDM0 and PVDM1 to be pooled and shared for use by the FXO ports and digital voice ports (such as T1 ports). This functionality provides support for 30 voice calls on T1 or E1 controller(s) plus eight FXO calls through the MRP3-8FXOM1 interface simultaneously. See the "DSP Groups and PVDM Guidelines" section for additional information.


Note The MRP3-8FXOM1 card is supported for use in North American M1-compliant countries (meeting North American M1 requirements for 600-ohm resistive termination).

For additional information about the MRP3-8FXOM1 card, refer to the Cisco ICS 7750 Installation and Configuration Guide and the Cisco ICS 7750 Troubleshooting Guide. For additional information about PVDM usage, refer to Understanding the Use of Codecs, DSPs, and Transcoding on the Cisco ICS 7750.


The MRP3-8FXS, MRP3-16FXS, and MRP3-8FXOM1 cards each ship with 64 MB of onboard RAM and can support 64 MB of add-on memory. You can install the following types of modules in an MRP3-8FXS, MRP3-16FXS, or MRP3-8FXOM1 card:

DIMM. MRP3-8FXS, MRP3-16FXS, and MRP3-8FXOM1 cards have one DIMM slot. Installing a DIMM increases the DRAM of these cards. The maximum amount of RAM that is currently supported on the MRP3-8FXS, MRP3-16FXS, and MRP3-8FXOM1 cards is 128 MB.

PVDM. MRP3-8FXS, MRP3-16FXS, and MRP3-8FXOM1 cards have two PVDM slots. Installing or replacing a PVDM gives these cards additional DSPs for processing heavier voice traffic loads. (Refer to Chapter 6, "Configuring the Cisco ICS 7750," in the Cisco ICS 7750 Installation and Configuration Guide for additional information about DSP resources on MRP cards.)

SIMM. The MRP3-8FXS, MRP3-16FXS, and MRP3-8FXOM1 cards each have one SIMM Flash memory module slot. These cards have 16 MB of onboard Flash memory, and they also have a SIMM slot for increasing the Flash memory up to 80 MB by adding 16-MB, 32-MB, or 64-MB SIMMs.

DSP Groups and PVDM Guidelines

This section provides additional information about the use of DSP groups and PVDMs.

DSP Groups

DSPs are located on the PVDMs on the ASI and MRP cards and are divided into DSP groups. A DSP group is a logical set of DSPs that could be used to handle calls on a set of voice ports. All the DSPs on a PVDM belong to only one group. Each DSP can perform a maximum of 100 million instructions per second, enabling greater processing power on an ASI or MRP. There can be up to five DSPs on a single PVDM and up to two PVDMs on an ASI or MRP card.

The Cisco IOS software that is packaged with ICS System Software 2.6.0 includes the capability for DSP resources in PVDM0 and PVDM1 to be pooled and shared for use by the FXO ports and digital voice ports (such as T1 ports). Resource sharing enables the most efficient use of DSPs.

With this release, support is provided for 30 voice calls on T1 or E1 controller(s) plus eight calls through the FXO interface simultaneously. The remaining DSP resources can be used for transcoding, in which one transcoding session is equal to two voice channels. The total number of voice channels cannot exceed 48 on the Flash-based MRP cards.

The number of DSP groups that are created is dependent on two variables:

Configuration of the tdm connected command (see the "New CLI Commands" section)

The number of voice clocking domains

The presence or absence of analog or BRI VICs in the chassis does not affect the number of DSP groups that are created.

Prior to this shared DSP support, two DSP groups were created when analog and digital ports were installed in two different slots in the Cisco ICS 7750 chassis. This system configuration resulted in the use of a single PVDM by the digital ports, with the second PVDM being used for the analog ports and transcoding activity. This did not allow for sharing of the PVDMs or the full availability of DSP resources, now both of which are supported in the version of the Cisco IOS software that is included in ICS System Software 2.6.0.


Tip To configure and use all 24 channels (on a T1) or 30 channels (on an E1) on port 1 of the T1/E1 on the MRP3-8FXOM1 card, the T1 or E1 should not share the PVDM with the PVDM used for the FXO ports. This configuration ensures that all DSPs on the PVDM are available for the T1 or E1 port; the T1 or E1 in port 0 (regardless of the slot number) is allocated a dedicated PVDM, and the T1 or E1 in port 1 is configured to share the PVDM with any FXO, FXS, and/or the VIC-2BRI-NT/TE (2-port BRI VIC) ports installed in the second slot.


New CLI Commands

Two new command-line interface (CLI) commands are available for use on the Flash-based MRP cards beginning with ICS System Software release 2.6.0.

The [no] tdm connected command controls the number of DSP groups that are created when there is only one voice T1 or E1 clocking domain in the system.


Tip It is recommended that you use the tdm connected command when there is only one T1 or E1 port configured for voice (or voice and data) installed in the system.


The following are guidelines for using the [no] tdm connected command:

If you do not configure tdm connected, the default configuration creates two DSP groups if there is a mixture of analog, BRI and T1 or E1 ports installed; PVDMs are never shared in this situation.

If you do configure tdm connected, the following DSP groups are created (irrespective of the types of VICs installed):

Single voice T1 or E1 clocking domain—One DSP group

Two voice T1 or E1 clocking domains—Two DSP groups

When tdm connected is configured, a subsequent tdm clock command that configures a port for voice (or both voice and data), or a subsequent reload, will result in the creation of a single DSP group (irrespective of the number of T1s or E1s, and analog VICs installed) except when there are two voice T1 clocking domains.

The [no] tdm multichannel command enables QUICC Multichannel Controller (QMC). This command provides support for up to a maximum of eight channel groups, PRI data (PRI-D) channels, or PRI dialer calls on a single T1 or E1 controller on an MRP, with supported speeds on the individual channels of 48 kbps, 56 kbps, and 64 kbps. If multichannel support is not enabled, speeds of 48 kbps and 56 kbps are not supported.

Use the following command to enable the multichannel feature (this feature is not enabled by default):

[no] tdm multichannel {E1/T1} slot/port number timeslot range

where range is 1-24 or 1-31. The default is to have all timeslots in Serial Channel Controller (SCC) non-multichannel support mode.

Codec Complexity

Also available with ICS System Software Release 2.6.0 is a new codec complexity command. This command is used to select the DSP image to be applied to the DSPs in the PVDM corresponding to the VIC card slot.

The number of channels per DSP that can be supported on the MRP card depends on the codec complexity that is configured and on the DSP image (firmware) being used on an individual VIC.

Analog and BRI ports use analog DSP firmware; E1 and T1 ports use Flexi DSP firmware. Each image is capable of handling a different number of voice channels. The number of DSPs that are required on each analog DSP firmware is calculated and loaded on the DSPs, based on the number of analog or BRI ports in the group. The remaining DSPs in the group are loaded with Flexi DSP firmware.

When a call is made on a voice port, it uses a DSP from the DSP group to which the voice port belongs. If a DSP serves both analog and E1 or T1 ports, calls originating from the analog ports use only the DSPs that are loaded with analog DSP firmware, and calls originating from the E1or T1 ports use only the DSPs that are loaded with the Flexi DSP firmware.

The VIC on the MRP3-8FXOM1 card uses a default DSP firmware of medium complexity. Using the command-line interface, you can configure the codec complexity command to select the DSP image to be applied to the DSPs in the PVDM corresponding to the VIC card slot. This will determine the codecs that are supported. The [no] form of the codec complexity command restores the medium- complexity default.

The codec complexity command is supported only on the 4-port, 8-port, and 16-port analog VICs, such as the VIC-4FXS/DID, MRP3-8FXS, MRP3-16FXS, and MRP3-8FXOM1 cards. Refer to the "Processor Cards Feature Summary" section of the Cisco ICS 7750 System Description for additional information.


Note For additional information about the tdm commands and codec complexity, refer to Chapter 7, "Cisco ICS 7750 Sample Configurations," in the Cisco ICS 7750 Installation and Configuration Guide, and Chapter 9, "Solving Voice Problems" in the Cisco ICS 7750 Troubleshooting Guide.


PVDM Guidelines

The following are general guidelines for using PVDMs.

The use of a PVDM-20 module is subject to a limitation on the MRP and ASI motherboard. The general rules are as follows:

If the PVDMs are shared by the VICs on the MRP or ASI (as one DSP group), only the first four DSPs from each PVDM are accessible.

For example, if only one T1 or E1 port is configured for voice, and there are no other analog or BRI VICs installed in the system, the PVDMs could be shared as long as the tdm connected command has been configured. In this situation, only four DSPs on each PVDM can be used, so a PVDM-20 will be treated as a PVDM-16. The recommendation is to use a PVDM-16 instead of a PVDM-20.


Tip You must configure the tdm connected command in order for the PVDMs to be shared. The default configuration creates two DSP groups unless tdm connected is configured and there is a single voice clocking domain.


If the PVDMs are not shared, then all five DSPs on a PVDM-20 are usable.

PVDMs are not shared (i.e., two DSP groups are formed) in the following situations:

Mixed analog VIC and T1 or E1 VWIC—For example, slot 0 has a VIC-2FXS, slot 1 has a 2MFT-T1, and tdm connected is not configured, or tdm connected is configured along with two voice T1 or E1 clocking domains.

Mixed BRI VIC and T1 or E1 VWIC—For example, slot 0 has a VIC-2BRI-NT/TE, slot 1 has a 1MFT-E1, and tdm connected is not configured, or tdm connected is configured along with two voice T1 or E1 clocking domains.


Note In the above situations, if the tdm connected command is used and only one voice clocking domain is configured, the PVDMs will be shared.


Two T1 or E1 ports are configured for voice (or voice and data) using the tdm clock commands, defining two voice clock source domains. In this situation, two DSP groups are created regardless of the mixture of VICs installed and regardless of whether the tdm connected command is configured.

In the above situations, a PVDM-20 can be fully used.

If you have only one 1MFT-T1 installed in the MRP, and the other WIC slot is empty, PVDM-16 modules are recommended. One PVDM-16 is sufficient for a full voice T1 using G.711 and maximum echo-cancellation (32 ms). Two PVDM-16 modules would suffice for a full voice T1 with G.729a and 32-ms echo-cancellation. A PVDM-20 is required for E1 ports.

You can determine whether the PVDMs are shared by using the CLI and executing the show voice dsp command from the MRP.


Note For additional information about PVDM usage and an example output of the show voice dsp command, refer to Understanding the Use of Codecs, DSPs, and Transcoding on the Cisco ICS 7750.

For information about voice compression algorithms and PVDM recommendations for ASI and MRP cards, refer to the Cisco ICS 7750 Installation and Configuration Guide.


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.

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 7 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 7 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.
