System Event Log-Event Configuration 
Having ticked the Syslog/SMTP checkboxes, 
the event log/email alert will be sent to

This page includes the following fields: 
 
Object Description 
System event selection: There are 4 event types—Device Cold Start, Device Warm Start, 
Authentication Failure, and X-ring Topology Change. The 
checkboxes are not available for ticking unless the Syslog Client 
Mode on the Syslog Configuration tab and the E-mail Alert on the 
SMTP Configuration tab are enabled first. 
Device cold start: When the device executes cold start action, the 
system will issue the event log/email alert to the system log/SMTP 
server respectively. 
Device warm start: When the device executes warm start, the 
system will issue the event log/email alert to the system log/SMTP 
server respectively. 
Authentication Failure: When the SNMP authentication fails, the 
system will issue the event log/email alert to the system log/SMTP 
server respectively. 
X-ring topology change: When the X-ring topology has changed, the 
system will issue the event log/email alert to the system log/SMTP 
server respectively. 
Port event selection: 
Also, before the drop-down menu items are available, the Syslog 
Client Mode selection item on the Syslog Configuration tab and the 
E-mail Alert selection item on the SMTP Configuration tab must be 
enabled first. Those drop-down menu items have 3 selections—Link 
UP, Link Down, and Link UP & Link Down. Disable means no event 
will be sent to the system log/SMTP server. 
Link UP: The system will only issue a log message when the link-up 
event of the port occurs. 
Link Down: The system will only issue a log message when the link-
down event of port occurs. 
Link UP & Link Down: The system will issue a log message at the 
time when port connection is link-up and link-down.

Fault Relay Alarm 
The Fault Relay Alarm function provides th e Power Failure and Port Link Down/Broken 
detection. With both power input 1 and po wer input 2 installed and the check boxes 
of power 1/power 2 ticked, the FAULT LED indi cator will then be possible to light up 
when any one of the power failures occu rs. As for the Port Link Down/Broken 
detection, the FAULT LED indicator will light up  when the port failure occurs; certainly 
the check box beside the port  must be ticked first. Please refer to the segment of 
Wiring the Fault Alarm Contac t for the failure detection.

This page includes the following fields: 
 
Object Description 
Power Failure: Tick the check box to enable the function of lighting up the FAULT 
LED on the panel when power fails. 
Port Link Down/Broken: Tick the check box to enable the function of lighting up FAULT LED

SNTP Configuration 
SNTP (Simple Network Time Protocol) is a simplified version of NTP, which is an 
Internet protocol used to synchronize  the clocks of computers to some time 
reference. Because time usually just advances,  the time on different node stations will 
be different. With the communicating progra ms running on those devices, it would 
cause time to jump forward and back, a no n-desirable effect. Therefore, the switch 
provides comprehensive mechanisms to  access national time and frequency 
dissemination services, organize the time-syn chronization subnet and the local clock 
in each participating subnet peer. 
Daylight saving time (DST) is the convention  of advancing clocks so that afternoons 
have more daylight and mornings have le ss. Typically clocks are adjusted forward 
one hour near the start of spring  and are adjusted backward in autumn. 
Figure 5-15:  SNTP Configuration interface 
 
This page includes the following fields: 
 
Object Description 
SNTP Client:  Enable/disable SNTP function to get the time from the SNTP server. 
Daylight Saving Time: This is used as a control switch to enable/disable daylight saving 
period and daylight saving offset. Users can configure Daylight Saving 
Period and Daylight Saving Offset in a certain period time and offset 
time while there is no need to enable daylight saving function. 
Afterwards, users can just set this item as enable without assign 
Daylight Saving Period and Daylight Saving Offset again.

UTC Timezone:  Universal Time, Coordinated. Set the switch location time zone. The 
following table lists the different location time zone for your reference. 
SNTP Sever URL: Set the SNTP server IP address. You can assign a local network time 
server IP address or an internet time server IP address. 
Switch Timer: When the switch has successfully connected to the SNTP server whose 
IP address was assigned in the column field of SNTP Server URL, the 
current coordinated time is displayed here. 
Daylight Saving Period: Set up the Daylight Saving beginning date/time and Daylight Saving 
ending date/time. Please key in the value in the format of ‘YYYYMMDD’ 
and ‘HH:MM’ (leave a space betw
een ‘YYYYMMDD’ and ‘HH:MM’). 
YYYYMMDD: an eight-digit year/month/day specification. 
HH:MM: a five-digit (including a colon mark) hour/minute specification. 
For example, key in ‘20070701 02:00’  and ‘20071104 02:04’ in the two 
column fields respectively to represent that DST begins at 2:00 a.m. on 
March 11, 2007 and ends at 2:00 a.m. on November 4, 2007. 
Daylight Saving Offset 
(mins):  For non-US and European countries, specify the amount of time for 
day light savings. Please key in the valid figure in the range of minute 
between 0 and 720, which means yo
u can set the offset up to 12 
hours.

IP Security 
IP security function allows  the user to assign 10 specific IP addresses that have 
permission to manage the switch throug h the http and telnet services for the 
securing switch management. The purpos e of giving the limited IP addresses 
permission is to allow only the authorized  personnel/device can do the management 
task on the switch.

Object Description 
IP Security Mode: Having set this selection item in the Enable mode, the Enable HTTP 
Server, Enable Telnet Server checkboxes and the ten security IP column 
fields will then be available. If not, those items will appear in grey. 
Enable HTTP Server: Having ticked this checkbox, the devices whose IP addresses match 
any one of the ten IP addresses in the Security IP1 ~ IP10 table will be 
given the permission to access this switch via HTTP service. 
Enable Telnet Server: Having ticked this checkbox, the devices whose IP addresses match 
any one of the ten IP addresses in the Security IP1 ~ IP10 table will be 
given the permission to access this switch via telnet service. 
Security IP 1 ~ 10: The system allows the user to assign up to 10 specific IP addresses for 
access security. Only these 10 IP addresses can access and manage 
the switch through the HTTP/Telnet service once IP Security Mode is 
enabled. 
 
NOTE: 
Remember to execute the Save Config uration action, otherwise the new 
configuration will be lost wh en the switch powers off.
