Information about the Cooling Unit

Identification

Use this option to define the System Name, Contact, and Location values used to identify the cooling
unit. For example, you might configure Name as Test Lab, Contact (whom to contact about the device)
as Donald Adams, and Location as Building3.

Date & time

Mode. Use this option to set the time and date used by the cooling unit. The option displays the current
settings, and allows you to change those settings manually or through a Network Time Protocol (NTP)
Server.
• Manual: Use this selection to do one of the following:
– Enter the date and time for the cooling unit
– Mark the checkbox Apply Local Computer Time to match the date and time settings of the
computer you are using, and click Apply.
• Synchronize with NTP Server: Use this selection to have an NTP Server define the date and
time for the cooling unit.
Enable and configure Daylight Saving Time. Use this option to enable either traditional United
States Daylight Saving Time (DST) or to enable and configure a customized daylight saving time, with
starting and ending dates and time that you specify to match how Daylight Saving Time is implemented
in your local area. DST is disabled by default.
When customizing Daylight Saving Time:
• If the local Daylight Saving Time always starts or ends on the 4th occurrence of a specific
weekday of a month (for example, the 4th Sunday), choose Fourth/Last. If a 5th Sunday occurs in
that month in a subsequent year, the time setting will still change to or from Daylight Saving Time
on the 4th Sunday.
• If the local Daylight Saving Time always starts or ends on the last occurrence of a specific
weekday of a month, such as the last Sunday of that month, regardless of whether that last Sunday
is the 4th or the 5th Sunday, choose Fifth/Last.
