Setting the System Clock
Maintaining accurate time is important for statistics and auditing. The InfiniBand chassis provides an
on-board system clock to save the time settings across reboots. Time is maintained in one of two ways:
•
An on-board system clock
•
External NTP servers
Time is set at the factory, and can be manually set. To ensure accurate synchronization, it is
recommended that you use an external NTP server. This enables logs to be synchronized with other
management systems.
Setting Time Manually
To set the system clock in the Element Manager:
1. In the Element Manager, select
Maintenance
->Time…
.
2. Enter the time manually in the
Time
and
Date
fields.
It is recommended that you use NTP servers to maintain the system clock because it assures
accuracy and avoids the potential time drift inherent to unsynchronized clocks.

Synchronize the Clock to an NTP Server
This section shows you how to use the Element Manager to synchronize the Topspin system clock with
an NTP server:
1. In the Element Manager, select
Maintenance
->Time…
.
The
Chassis Time
window opens.
2. Ignore the
Date
and Time
group; it will be reset automatically by the NTP servers.
3. In the
NTP Servers
group, enter the IP addresses of the NTP servers in the
NTP
Server1
,
NTP
Server2
, and
NTP
Server3
fields.
