4.185 disc-imt

The interprocessor message transport bus (IMT bus) is the main communications artery between all subsystems in the system. Use this command to disconnect a card from the specified IMT bus.

Note:

When a card is disconnected from the IMT Bus, it may take several seconds for the card IMT Status to be updated. If an init-mux or disc-imt command is entered for the alternate IMT Bus before the card IMT Status is updated, then the card may reboot. After disconnecting the card from the IMT bus, use the rept-stat-imt or rept-stat-card command to determine whether the card IMT status is updated. Do not issue the disc-imt or init-mux command for the alternate IMT bus until the card status is updated.

Parameters

bus (mandatory)

IMT bus to be disconnected from.

Range:

a, b

loc (mandatory)

The card location as stenciled on the shelf of the system.

Range:

1101 - 1108, 1111 - 1112, 1201 - 1208, 1211 - 1218, 1301 - 1308, 1311 - 1318, 2101 - 2108, 2111 - 2118, 2201 - 2208, 2211 - 2218, 2301 - 2308, 2311 - 2318, 3101 - 3108, 3111 - 3118, 3201 - 3208, 3211 - 3218, 3301 - 3308, 3311 - 3318, 4101 - 4108, 4111 - 4118, 4201 - 4208, 4211 - 4218, 4301 - 4308, 4311 - 4318, 5101 - 5108, 5111 - 5118, 5201 - 5208, 5211 - 5218, 5301 - 5308, 5311 - 5318, 6101 - 6108, 6111 - 6118

Example

disc-imt:loc=1213:bus=b

Dependencies

Valid IMT bus entries are "A" or "B".

This command cannot be entered during an IMT Fault Isolation Test. The card cannot be isolated from both IMT busses.

When disconnecting a card from one IMT bus, the other (alternate) IMT bus must be in a known, good (IS-NR) state.

The card location, frame, shelf, or slot must be within the allowed range.

This command cannot be entered if an IMT Rate Change sequence is in progress.

This command cannot be entered during an IMT Fault Isolation Test or an Extended Bit Error Rate Test (BERT).

Notes

The card can be reconnected by issuing the conn-imt command, or by re-inserting the card. A software reset does not affect connect status. (The init-card command performs a software reset.)

Output

disc-imt:loc=1213:bus=b
