EIU MAP level

EIU information is available on the maintenance and administration position command interface (MAPCI) display under the PM level. The command to access the EIU MAP display is as follows:

>MAPCI;MTC;PM;POST EIU nALL

where

n is the EIU index

The maintenance actions implemented for an EIU are similar to those required for any other application-speciﬁc unit (ASU) on the LPP.

Manual busy state

The EIU can be set to the manual busy state from the following states:

•Ofﬂ, the off-line state

•InSv, the in-service state

•IsTb, the in-service trouble state

On the MAP display, manual busy is shown as ManB.

The EIU software load can be downloaded to the EIU processor only in the ManB state through the LOADPM command. When the EIU is in either the ManB or the Ofﬂ states, it is not actively transmitting messages on the Ethernet LAN. However, in a ManB state, if the EIU contains the correct IP address information database, it may communicate to other SuperNode nodes, such as function processor (FP) or computing module (CM).

In-service state

The EIU can be set to the InSv state only from ManB state. When the EIU is returned to service, the IP address database along with other IP throttling and engineering data is downloaded to the EIU. When the EIU is in the InSv or IsTb state, it can actively communicate to both the Ethernet LAN and the frame transport bus (F-bus).

EIU diagnostics

EIU diagnostics run in the background. This section describes the diagnostics provided for the EIU.

Out-of-service diagnostics

A complete set of EIU out-of-service diagnostics are executed during the ManB to InSv state transition. The EIU is not allowed to return to service if any one part of the diagnostics fail. The faulty card-list does not appear on the MAP display and the system generates PM logs that can help isolate the faulty card. The components level isolation of the fault is not available through logs
