LEDs

The LEDs indicate the current operating condition of the feature cards. Observe the LEDs (see Figure 7-1 through Figure 7-4), note any fault condition that the product is encountering, and then contact your system administrator or a customer service representative. (See the "Obtaining Technical Assistance" section on page xvi, if necessary.) Table 7-1 describes the LEDs.

Mixing WAN Feature Cards

The Cisco AS5350XM and Cisco AS5400XM universal gateways support only one type of WAN feature card at a time. The feature cards that can be installed at one time are:

Up to three T1 feature cards (any combination of 2-, 4-, or 8-port) or

Up to three E1 feature cards (any combination of 2-, 4-, or 8-port) or

One CT3 feature card or

One CT3 feature card and up to two T1 feature cards (any combination of 2-, 4-, or 8-port)

The universal gateway software recognizes feature cards in the order of the slots they are in. For example, a feature card in slot 2 is recognized before a feature card in slot 3. The system recognizes whether there is a mix of WAN feature cards during both power up and OIR:

During power up, the first WAN feature card recognized by the system is the only type brought up.

If there are two or more WAN feature cards of the same type and one is hot-swapped with another of a different type, the new one is not recognized.

In both situations, an error message will appear on the console that is similar to this example:

00:01:12:%CARRIER-2-T1_E1_MIX:Cannot mix T1 and E1 8PRI DFC cards in chassis, do not power 
up invalid card in slot 7

Mixing Universal Port and Dial-Only Feature Cards

If a dial-only feature card is installed in a chassis with the universal port feature card, only dial services are supported. Table 7-2 describes the behavior of the Cisco AS5350XM and Cisco AS5400XM universal gateways with dial-only feature cards, universal port feature cards, or both installed in the chassis.


Caution We do not recommend deploying dial-only feature cards in a chassis that supports voice and fax services, because voice or fax calls assigned to the dial-only feature card will fail.

Services Supported

Mixing Voice Feature Cards With Universal Port and Dial-Only Feature Cards

Voice feature cards are not compatible with universal port and dial-only feature cards. Voice feature cards should not be installed on any system that has universal port and dial-only feature cards. Table 7-3 describes the behavior of the Cisco AS5350XM and Cisco AS5400XM universal gateways depending on whether the voice feature card is present at power on.

Table 7-3 Voice Feature Card Support During Power On

Feature Cards Present at Power On
Feature Cards Supported

Voice feature card present at power on

Voice feature card only. Any universal port and dial-only feature cards present will not be operational until the voice feature card is removed and the system is rebooted.

Voice feature card not present at power on

Universal port or dial-only feature cards only. Any voice feature card installed later will not be operational until the system is rebooted.



Note If you plan to use voice feature cards, at least one voice feature card must be present when the universal gateway is powered on. More voice feature cards can be installed later.


Monitoring the Chassis Environment

The Cisco AS5350XM and Cisco AS5400XM universal gateways contain temperature sensors to detect abnormal temperature conditions during system operation. The three levels of sensor detection are as follows:

1. When the operating temperature of the system exceeds 113×F (45×C), the system reaches a warning state. A warning message appears on the console. When the operating temperature of the system drops below 113×F (45×C), another message is displayed on the console, indicating a recovery. At this level of sensor detection, there is no disruption in system operation.

2. When the operating temperature of the system continues to rise above 113×F (45×C) and reaches a temperature of 140×F (60×C), the system reaches a critical state.

Cisco IOS software busys out the feature cards in the chassis and shuts down the first feature card. If the operating temperature continues to be critical after 10 minutes, Cisco IOS software shuts down another feature card.


Note Feature card slot numbering starts at the system board and slots are numbered sequentially from the bottom row up, left to right. Slot 0 is reserved for the motherboard. (See Figure 7-5 and Figure 7-6.)


Figure 7-5 Slot Numbering on the Cisco AS5350XM Chassis

Figure 7-6 Slot Numbering on the Cisco AS5400XM Chassis

The busyout process is repeated at 10-minute intervals until the final feature card is shut down. The console displays the slot number of the feature card and the type of feature card that was shut down.

If the operating temperature cools down to 113×F (45×C), Cisco IOS software powers on the first feature card, repeating the process for each feature card at 10-minute intervals.

3. When the operating temperature of the system rises above 149×F (65×C), Cisco IOS software shuts down all feature cards immediately.

Displaying Environment Status

You can use the command-line interface (CLI) to check environment monitoring status of your universal gateway.

To check environment status, enter the show environment command in privileged EXEC mode.

Router# show environment

The output shown below displays on your console during normal operating conditions. The slot number corresponds to the feature card in that slot. The outlet and inlet sensors read the temperature of the air circulating inside the chassis.

Using the Bantam Jack Ports to Monitor T1, E1, and CT3 Feature Cards

Monitor mode is available on the T1, E1, and CT3 feature cards. If a T1 controller does not come up, or if a large number of errors are associated with a particular controller, you might be able to use the test port to determine whether the problem is in the feature card or in an external T1 line. by using the test port. The test port is a set of bantam jack ports located on the front panel of the T1, E1, and CT3 feature cards. (See Figure 7-7.)

Figure 7-7 Bantam Jack Ports

In monitor mode, you can monitor only the ingress side of the T1 line without disrupting that line.

The bantam jack ports located on the front panel of the feature cards allow the connection of an external test device (for example, a FIREBERD test device) to monitor the individual T1 circuits in monitor mode. Use software commands to select a T1 line. For information on software commands, see the Cisco AS5350XM and Cisco AS5400XM Universal Gateways Software Configuration Guide.

Passive monitoring equipment is used to listen on the TX MON and RX MON jacks during regular operation to detect T1 errors.

Connecting test equipment to the following bantam jack ports provides various functions:

TX MON can monitor signals coming out of the test port without interrupting normal data transmission.

RX MON can monitor signals going in to the test port without interrupting normal data transmission.

Using Drop and Insert Mode on the CT3 Feature Card

The bantam jack ports located on the front panel of the CT3 feature card allow the connection of an external test device (for example, a FIREBERD test device) to test any of the 28 individual T1 circuits in drop and insert mode. Once drop and insert mode is enabled, a T1 circuit can be dropped out of service by using the push button on the CT3 feature card.

The test trunk drop-insert privileged EXEC command is used to enable or disable drop and insert mode on a T3 controller. When the system initially boots up, the drop and insert mode is disabled on all T3 controllers.

To drop a T1 circuit to a test port, follow these steps:


Step 1 Enable drop and insert mode by entering the test trunk drop-insert on port-number privileged EXEC command as follows:

Router# test trunk drop-insert on port-number


Note The port-number is the T1 circuit that you wish to drop. T1 port numbers range from 1 to 28.


Step 2 Disable drop and insert mode after testing the T1 circuits.


Note We recommend that you disable drop and insert mode to prevent accidental use of the push button on the CT3 feature card.


To disable drop and insert mode, enter the test trunk drop-insert off port-number privileged EXEC command as follows:

Router> test trunk drop-insert off port-number
