Chapter 2 Installing and Removing Management Blades
2.3.4 Blade Server Time Management
It is necessary to perform/check Management Blade time and time zone settings during initial setting.
Perform checks/settings in Web UI ( "● System Information" (p.45)) or CLI ( "■ Management Agent
Information (1_1)" (p.71)).
Note the following when checking/setting.
■ Server Blade and Management Blade time synchronization
The time of the Server Blade installed in the chassis can be synchronized with the time of the
Management Blade by enabling "Sync RTC with Mgmt. Blade" using the BIOS setup (Default value is
[Enabled]).
Using this function, the time of multiple Server Blades and Management Blades installed in the chassis
can be synchronized.
→ "BX620 S4 Server Blade User's Guide Chapter 8 Hardware Configuration/Utilities"
■ Management Blade time synchronization via the network
Disable "Sync RTC with Mgmt. Blade" if you do not wish to perform time synchronization for Server
Blade and Management Blade for reasons such as a precise system time being demanded of the
Server Blade. In this case incorporate a time synchronization system (NTP etc.) via the network in
the Server Blade system design.
Management Blade supports NTP as a time synchronization system via the network. Set in Web UI ( "•
NTP" (p.40)) or CLI ( "● 17. Agent NTP (1_1_17)" (p.78)). When using this function, complete
settings or checking before starting blade server operations or when suspended.
Do not change NTP settings during blade server operation. Doing so may cause a system failure by
the time synchronization of the Management and Server Blades in the OS etc.
