18.3 Specification Tables
The NSA hardware specifications are shown in the following table.
DyDNS Dynamic DNS allows you to update your current
dynamic IP address with a dynamic DNS service so
that anyone can contact you (in NetMeeting, CUSeeMe,
etc.). You can also access your FTP server or Web site
on your own computer using a domain name (for
instance myhost.dhs.org, where myhost is a name of
your choice) that will never change instead of using an
IP address that changes each time you reconnect. Your
friends or relatives will always be able to call you even
if they don't know your IP address.
Download Service The NSA’s download service downloads files from the
Internet directly to the NSA. You do not have to
download to your computer and then copy to the NSA.
This can free up your computer’s system resources.
The download service also handles your broadcatching
downloads.
Power Schedule Use this screen to manage power settings for the NSA,
including power saving, UPS, power on/off during
power failure and power on/off schedule.
