Troubleshooting the SLSA Subsystem

Recovering From a SLSA Adapter Alarm
Note: The following instructions are applicable to the OSM package or to TSM client 5.0 or later and
TSM server version T7945AAE (G06.02 RVU) or later.
This page explains how to recover from a ServerNet LAN Systems Access (SLSA) subsystem alarm
displayed by the OSM Service Connection or TSM Service Application.
Click the alarm you are interested in for recovery information:
Power-On Self-Test Failed Alarm●
Too Many State Transitions Alarm●
Incorrect Logical Configuration Alarm●
Hardware Error Alarm●
Wrong PIC Type Alarm●
Power-On Self-Test Failed Alarm
This alarm is generated for a ServerNet addressable controller (SAC) when the power-on self test
(POST) fails.
Note: The POST is executed whenever the SAC is started through OSM, TSM, or SCF. You can also
explicitly execute a POST on a SAC by performing the Test Verify test action from the OSM Service
Connection or TSM Service Application.
To recover from this alarm when it is generated for a SAC on an E4SA, TRSA, FESA, or GESA, or when
it is generated for an ATM3SA, you must replace the adapter. For replacement instructions, see:
ATM3SA: ATM Adapter Installation and Support Guide●
E4SA: Replacing an E4SA CRU procedure●
FESA: Fast Ethernet Adapter Installation and Support Guide●
GESA: Gigabit Ethernet Adapter Installation and Support Guide●
TRSA: Replacing a TRSA CRU procedure●
To recover from this alarm when it is generated for a SAC on a CCSA CRU, you must replace the plug-in
card (PIC) on which the SAC is located. For information about replacing a PIC, see Replacing or Installing
ServerNet Adapter Plug-In Cards (PICs).
Too Many State Transitions Alarm
Note: The Too Many State Transitions alarm can be generated for many different reasons; some of
the most common reasons are described below. You should examine the event log for events generated
in the same timeframe as the alarm to help determine the actual cause of the alarm.
This alarm is generated for a ServerNet addressable controller (SAC). The cause of and recovery from
this alarm depend on the type of adapter as follows:
For ATM ServerNet Adapters (ATM3SAs), Common Communication ServerNet Adapters (CCSAs),
