272 Managing General System Settings
The switch can obtain the time from a Simple Network Time Protocol 
(SNTP) server, or you can set the time manually. Table 11-2 describes the 
settings that help the switch keep track of time.
The PowerConnect 7024P and 7048P switch ports are IEEE 802.3at-2009-
compliant (PoE Plus) and can provided up to 30W of power per port. For 
more information about PoE Plus support, see "What Are the Key PoE Plus 
Features for the PC7024P and PC7048P?" on page 275
Why Does System Information Need to Be Configured?
Configuring system information is optional. However, it can be helpful in 
providing administrative information about the switch. For example, if you 
manage several standalone PowerConnect 7000 Series switches and have

Table 11-2. Time Settings
Feature Description
SNTP Controls whether the switch obtains its system time 
from an SNTP server and whether communication 
with the SNTP server requires authentication and 
encryption. You can configure information for up to 
eight SNTP servers. The SNTP client on the switch can 
accept updates from both IPv4 and IPv6 SNTP servers.
Real time clock (RTC) If SNTP is disabled, you can manually enter the system 
time and date.
Time Zone Allows you to specify the offset from Coordinated 
Universal Time (UTC), which is also known as 
Greenwich Mean Time (GMT).
Summer Time In some regions, the time shifts by one hour in the fall 
and spring. In the United States, this is called daylight 
saving time.
