What is the ePower
Reboot sequence?
When you Reboot an outlet, the outlet immediately
turns Off, then turns back On, after the Off-to-On
timer expires. The default Off-to-On delay time is
five seconds. The delay time can be changed in the
Outlet Properties dialog box, in the Web interface.
What happens if I change an
outlet’s state when the outlet
is in the process of Rebooting?
If you turn an outlet On or Off when that outlet is still
in the Reboot process, the Reboot is canceled, and
the outlet immediately changes to the desired state.
What happens if I change the
Off-to-On delay time when
an outlet is in the process
of Rebooting?
Each Reboot process uses the settings that were
applied at the time the Reboot was started. Any
changes made after the Reboot starts are used
for subsequent Reboot requests.
An outlet is not working,
and no alert was issued.
First, ensure that the equipment connected to the
outlet is fully plugged in, and that the equipment is
turned On. Next, try turning On the outlet from the
ePower Web interface, even if the outlet reports that
it is already On.
If this does not resolve the problem, contact

The message
jffs2_sum_write_data: Not enough
space for summary, padsize = XXXX.
appeared in the system log.
The Journaling Flash File System v2 (JFFS2) file
system used on the ePower is a highly reliable,
fault-tolerant, self-correcting file system designed
for performance on embedded systems.
This message indicates a common warning that
JFFS2 is using a new segment of Not-And (NAND)
gate flash and must first initialize that segment.
You can ignore this message, because it is used
only for internal kernel-level debugging.
