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.

Table D-1. Concentrator Capacity
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 the
concentrator end, then unplug at the source. You must wait 3 days for the
battery to completely drain before you reconnect this cable.
