ShoreTel IP Phone 930D Planning and Installation Guide 51
When a handset is returned to the charging stand, the LED indicator at the top of the handset shows
the progress of the upgrade:
1. Slow green flash after the handset is first placed into the charger for about 90 seconds—Checking
the transferred image for errors.
2. Fast green flash for about 60 seconds—Writing image to Flash.
3. Amber flash for about 30 seconds—Verifying image.
4. Red flash for about 10 seconds—Clearing downloaded image.
5. Handset restarts and shows the idle screen after a few seconds.
Repeater upgrades are completely automatic.
Understanding DECT Registration Security
White lists are used to limit the handsets and repeaters that may register with a given base. For bases,
the DectHandset parameter is placed in a MAC-specific configuration file associated with a base to
limit what handsets can register with that base. The DectHandset parameter also assigns an IP
address for each handset.
Similarly, the configuration parameter DectRepeaters is used to limit the repeaters that may register
with a given base. For repeaters, the DectRepeaters parameter is placed in a MAC-specific
configuration file associated with a base to limit what repeaters may register with that base.
Both handsets and repeaters use the registration code 0000. (You do not need to enter a registration
access code for repeaters; repeaters use 0000 automatically).
Understanding System Management
The IP930D system is primarily configured using downloadable configuration files, similar to the
ShoreTel IP Phone 230. However, the base and repeaters have special configuration needs that
require a browser-based interface called ShoreTel IP930D Manager.
WARNING!
Never remove a handset from the charging stand during the upgrade process, which takes
approximately four minutes. If the battery condition is marginal, the upgrade may not complete
properly if the handset is removed prematurely.
