Replacing a duplicated UCV-D card
Table 14:
OPERATION DETAILS OF THE OPERATION / COMMENTS
• Back up the customer
configuration.
• Precautionary operation to be carried out if there is no existing
copy (which is the case when previous installation operations
have been carried out and the procedures followed).
• Refer to [1]
• In the case of remote operation, contact the remote operator
before starting any operation.
• Disconnect the cables on
the UCV-D card to be
removed.
• Disconnect the external cables from the card and mark the
cables for refitting.
• Reconnect the cables to
another UCV-D card.
• Perform the wiring exactly as for the card to be removed.
Nota : A hardware anomaly detected on the active UCV-D
card triggers an automatic switchover of the UCV-D
card, which becomes passive. The second UCV-D
card takes over and becomes active.
After a switchover the duration of which depends on
the configuration (15 s. to 1 min.), the passive CPU
card takes over and becomes active in the following
three cases:
- if the active card is removed,
- if the active card remains idle for 2 minutes,
- if a hardware failure is detected on the active UCV-
D card (in this case, a hardware fault detection is
performed. The unavailability time on the cabinet
can, therefore, be up to 3 minutes).
Nota : If the iPBX has an expansion cabinet, the active
RUCV-D card is the one connected to the active
UCV-D card. In case of switchover to the UCV-D
card, there is also a switchover to RUCV-D. If for
example
UCV-D(A) becomes faulty, UCV-D(B) takes over and
becomes active. On the expansion cabinet side, it is
the RUCV(B) that is active (and RUCV(A) passive).
• Pull out the faulty card
from its slot.
• Use the 1/4 turn locks to remove the card from its slot
(see Figure 4.1 ).
Nota : The UCV-D card can be removed from an
operational AXD iPBX.
• Check that the functional
technical state of the new
card is compatible with
the old one.
