Installing Sfps And Attaching Cables; Installing An Sfp Into An Upper Port - IBM System Storage SAN32B-E4 Installation, Service And User Manual

Synchronizing local time with an external source
To synchronize the local time of the principal or primary switch with that of an
external NTP server, follow these steps.
1. If necessary, log on to the switch by Telnet, using the admin account.
2. Enter the tsClockServer command.
The following example shows how to set up more than one NTP server using a
DNS name:
switch:admin> tsclockserver "10.32.170.1;10.32.170.2;ntp.localdomain.net"
Updating Clock Server configuration...done.
Updated with the NTP servers
Changes to the clock server value on the principal or primary FCS switch are
propagated to all switches in the fabric

Installing SFPs and attaching cables

To install SFPs and cables to the switch, follow these steps.
1. If necessary, remove the plugs from the ports to be used.
2. Ensure that the bail (wire handle) is in the unlocked position. Place the SFP in
Figure 13. Installing an SFP into an upper port
3. Slide the SFP into the port until it clicks into place. Close the bail.

SAN32B-E4 Installation, Service, and User Guide
switch:admin> tsclockserver "<ntp1;ntp2>"
where ntp1 is the IP address or DNS name of the first NTP server, which the
switch must be able to access. The second ntp2 is the second NTP server and is
optional. The operand "<ntp1;ntp2>" is optional; by default, this value is LOCL,
which uses the local clock of the principal or primary switch as the clock
server.
The tsClockServer command accepts multiple server addresses in either IPv4,
IPv6, or DNS name formats. When multiple NTP server addresses are passed,
tsclockserver sets the first obtainable address as the active NTP server. The
others will be stored as backup servers that can take over if the active NTP
server fails. The principal or primary FCS switch synchronizes its time with the
NTP server every 64 seconds.
switch:admin> tsclockserver
LOCL
switch:admin> tsclockserver "132.163.135.131"
switch:admin> tsclockserver
