The hardware replacements require a different approach. The new equipment shall have new
MAC addresses and this causes a discontinuity in the measurements as it is considered a new
access point in the target network. If this is not the intention and the new equipment should
totally replace an access point that was previously in Managed more, 7signal Sapphire must be
informed.
To retain the measurement history with a new hardware:
1. Scan the network to get hold of the new access point hardware
2. Right-click on the access point that has been replaced to summon the edit dialog
3. Locate the replace panel and choose from the drop-down list the new access point that
shall assume the role of the replaced access point.
The intended use of this feature is to help with replacing identical hardware. If the hardware is
not identical, the results may be many-fold. SLAs and alarm thresholds should be checked, for
example.
Cisco controller-based environments use software MACs. The software MACs may
be re-shuffled. This is known to be happening during major controller software
upgrades. In this case the physical hardware remains exactly the same, just the
MAC has been reallocated. 7signal Sapphire replacement support guarantees the
continuity of the measurement history.
