In all the conditions described below, if RadioBlade transceivers are present in the
system that are in the hot-standby state, then locking the RadioBlade transceiver
(due to alarms, removal of a RadioBlade transceiver or administratively locking
RadioBlade transceivers) will result in the hot Standby Blade transceiver being
assigned to the BR that de-registered the locked RadioBlade transceiver.
8.6.3 Locking Policy for RadioBlade Transceiver with Errors
If the RadioBlade transceiver generates enough faults such that it crosses the
Bounce and Duration threshold for that particular error, an alarm will be
generated. The RadioBlade controller then notifies the associated BR, which then
locks the RadioBlade transceiver. This will result in disabling the BR.
If there is a faulty RadioBlade transceiver in the system (generating error alarms),
it is prevented from coming up after a commanded reset/system reset, but the
operator could manually unlock the RadioBlade transceiver, at which point the
RadioBlade transceiver would be assigned to a BR. (This would not prevent the
system from locking it again if an excessive error condition recurs).
A. Removal of RadioBlade Transceiver
When a RadioBlade transceiver is physically removed, an event is generated
in the System Manager Event Log notifying the user about the RadioBlade
transceiver removal. The RadioBlade controller will then de-register the
RadioBlade transceiver from the BR(s), which will result in locking the BR(s).
A RadioBlade transceiver Insert event is generated when the RadioBlade
transceiver is inserted into the system.
B. Administrative Locking of a RadioBlade Transceiver
By definition, administrative locking of a RadioBlade transceiver is in effect if
the RadioBlade transceiver lock icon on the RadioBlade Transceiver Status
page is changed to “locked”.
The Multi-Channel RadioBlade transceiver is treated as a unit (single RBID)
with respect to administrative locking.
The following rules apply to locking a RadioBlade transceiver.
• The BR(s) associated with the administratively locked RadioBlade
transceiver will go into a Disabled state. Only that RadioBlade
transceiver will lock, and its icon will change to “locked”.
• If an administratively locked RadioBlade transceiver is replaced, the new
RadioBlade transceiver will be considered unlocked upon insertion.
(Administrative locking applies to a particular RadioBlade transceiver and
not to a particular DRBS Slot).
