### Description

```asn1
salixSysHsfWorking OBJECT-TYPE
SYNTAX PhysicalIndex
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"The PhysicalIndex of the Hybrid Switch Fabric (HSF) module
plug-in unit that is performing switching in the SALIX.
Writing a new value to this variable will:

- update the salixHsfProtect object with the current
value of the salixHsfWorking object and

- activate the specified HSF module to start performing
ATM and TDM switching in the system.

A value of 0 indicates that there is no operational switch
fabric installed. Writing zero, an invalid index,
or the current value to this object will have no effect.

If the working HSF module fails, the system will automatically
switch to the HSF module specified in the salixHsfProtect object."
```
