Chapter 1 Safety Warnings, Recommendations, and Tools Required

Preventing Electrostatic Discharge

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, 10A international) is used

on the phase conductors (all current-carrying conductors). To see translations of the warnings that

appear in this publication, refer to the Regulatory Compliance and Safety Information document

that accompanied this device.

Preventing Electrostatic Discharge

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage occurs

when electronic components are improperly handled and can result in complete or intermittent failures.

Always follow ESD-prevention procedures when you remove and replace 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 grounding clip to an unpainted surface of the chassis frame to

safely ground unwanted ESD voltages. To guard against ESD damage and shocks, the wrist strap and

cord must operate properly. If no wrist strap is available, ground yourself by touching the metal part of

the chassis.

For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and

10 megohm (Mohm).

Overview

Cisco AS5350 Chassis

The Cisco AS5350 universal gateway chassis has a motherboard, high-speed backplane, and two

backplane slots. One backplane slot accepts one dial feature card (DFC) carrier card and the other

backplane slot accepts one DFC.

Cisco AS5400 Chassis

The Cisco AS5400 universal gateway chassis has a motherboard, high-speed backplane, and four

backplane slots. Three backplane slots accept DFC carrier cards and the other backplane slot accepts one

DFC.

Dial Feature Cards

Each DFC carrier card accepts two DFCs which allow online insertion and removal (OIR). (See

Figure 2-1.)

Each DFC is a 5.1 x 13 inch PCI based interface board. The following is a brief description of the trunk

types supported:

•North American robbed-bit signaling (RBS) is supported on T1 trunks, including a variety of North

American RBS protocol, framing, and encoding types on these trunks.

•CAS is supported for E1 trunks, with R2 signaling.

•Many countries require an E1 R2 variant. Per-country defaults are provided for supervisory and

inter-register signaling.

•The CT3 DFC provides physical line termination for a channelized T3 ingress trunk line, and it uses

an onboard multiplexer to multiplex 28 channelized T1 lines into a single channelized T3 line.

Chapter 2 Dial Feature Card and Carrier Card Guidelines

Online Insertion and Removal (OIR) of DFCs

•Universal access (analog modem or digital calls) is supported when an interface is configured for

ISDN PRI signaling. PRI signaling is available for both T1 and E1 trunks.

In any single DFC slot, you can install your choice of:

•One T1, E1, or T3 dial feature card

•One universal port card

Online Insertion and Removal (OIR) of DFCs

All DFCs on the Cisco AS5350 and Cisco AS5400 chassis support online insertion and removal (also

known as hot swapping). You can install, remove, replace, and rearrange the DFCs without turning off

the chassis power.

When the chassis detects that a DFC is installed or removed, it automatically runs diagnostic and

discovery routines, acknowledges the presence or absence of the DFC, and resumes chassis operation

without any operator intervention.

See:

•Chapter 3, “T1 and E1 Dial Feature Cards,” to perform OIR of the T1 or E1 DFC.

•Chapter 4, “T3 Dial Feature Card,” to perform OIR of the T3 DFC.

•Chapter 5, “Universal Port Dial Feature Card,” to perform OIR of the universal port DFC.

Removing and Installing Populated Carrier Cards

Caution The carrier cards that carry the DFCs are not hot swappable. Removing a card while the system is

still powered on may cause permanent damage to electronic circuits on the card.

The DFC carrier card plugs into one of the backplane slots and supports two DFCs. The carrier card

increases backplane capacity and allows OIR of the DFCs. (See Figure 2-1.)

Chapter 3 T1 and E1 Dial Feature Cards

Online Installation and Removal of the T1 or E1 DFC

Overview

To remove a DFC without dropping any calls or connections, you will need to take the DFC out of service

by using the busyout command to disable the DFC. The busyout command is executed on a per DFC

basis and will gracefully disable the card by waiting for the active services to terminate.

If you have active calls on the DFC after executing the busyout command, wait for the calls to drop. Use

the show busyout command to view the status of the termination process.

Caution The online installation and removal (OIR) of new cards should be done ONLY during times of low

CPU utilization, such as during maintenance.

Caution To avoid erroneous failure messages, remove or insert only one DFC at a time.

When you replace a DFC with a new DFC of the same type in the same slot, the system software will

recognize the new trunk interfaces and bring them up automatically.

If you replace the existing DFC with a new DFC of a different type, you will have to reconfigure the

system. For configuration details, refer to the Cisco AS5350 and Cisco AS5400 Universal Gateway

Software Configuration Guide.

Removing the T1 or E1 DFC

To remove the T1 or E1 DFC, follow these steps:

Note Following these steps are examples of the output from each command.

Step 1 Determine which slot the DFC is in by entering the show chassis command in privileged EXEC mode:

Router# show chassis slot

Chapter 3 T1 and E1 Dial Feature Cards

Online Installation and Removal of the T1 or E1 DFC

Figure 3-5 Slot Numbering on the Cisco AS5400 Chassis

Step 2 Initialize the software busyout procedure by entering the busyout command:

Router# busyout slot-number

Step 3 Enter the show busyout command to check busyout status for that specific slot:

Router# show busyout slot-number

Step 4 You may use the clear port command to immediately disable active calls on the universal port card

(UPC). For more information on the UPC, see Chapter 5, “Universal Port Dial Feature Card”. Use the

show controller command to show the universal port card associated with the T1 or E1 DFC.

Router# show controller t1/e1 slot-number/control-number timeslot timeslot-number

Router# clear port slot-number/port number

Note The clear port command only applies to the universal port DFC.

Step 5 Verify that the OIR/MAINT LED is off; this indicates that the DFC is offline and ready to be removed.

Note The OK/MAINT LED is green before you enter the busyout command. After you enter the

busyout command, the LED changes to yellow. The LED turns off after all calls are

disconnected and resources are taken out of service, indicating that busyout is complete.

Step 6 Attach an ESD-preventive wrist strap.

Warning

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

see translations of the warnings that appear in this publication, refer to the Regulatory

Compliance and Safety Information document that accompanied this device.
