Impact of Boot-up on Data Storage
The concentrator boot-up/reset impacts the data storage. The nature of the impact varies based on the
type of the boot-up. There are three kinds of boot-up:
• Cold Boot - DTT is cleaned up. ODE is cleaned up. The concentrator will not remember any
endpoints.
• Warm boot - DTT is intact. ODE is cleaned up. The concentrator remembers the endpoints it
heard. However, there are no database objects corresponding to them.
• Hot Boot - DTT is intact; and ODE is intact.

Cycling Power
To immediately reboot the concentrator, perform the following steps:
1. Disconnect the AC cable from its connection on the concentrator.
Disconnect the cable from the concentrator end, not the AC power source end.
Do not disconnect the battery cable. If you cannot reach the AC cable on th e
concentrator end, then unplug at the source. You must wait three days for t h e
battery to completely drain before you reconnect this c a ble.
2. Wait five seconds.
3. Re-connect the AC power cable to the concentrator.
