HP proliant bl e-class ユーザーズマニュアル

The interconnect switch can maintain the current date and time. This information displays on 
the management interfaces and is used to record the date and time of switch events. Current 
date and time information can be manually set on the interconnect swithc or can be obtained 
through Simple Network Time Protocol (SNTP). SNTP allows the interconnect switch to 
send a request to a primary or secondary SNTP server in each polling period asking for the 
Greenwich Mean Time (GMT). If the primary SNTP server is not available, the request is 
sent to a secondary SNTP server. 

For increased security, separate user accounts can be set up with various levels of permission. 

This section describes the external panel and LED indicators of the ProLiant BL e-Class  
C-GbE Interconnect Switch. 

The external panel of each interconnect switch has four RJ-45 connectors with Gigabit 
Ethernet uplink connectivity for network cabling. In addition, there are two Integrated 
Administrator connectors (one RJ-45 and one serial port) that support remote and local 
out-of-band management of the interconnect switch through a browser, SNMP/RMON, and 
Telnet console interfaces.
