Appendix E Notes
(2)
Hub for user LAN (100Base-TX), and LAN cables
l
This hub must be installed between the on-board LAN port on the system board of
the partition and the user LAN port of the SMC. Be sure to prepare hub and LAN
cables as required for the user LANs.
l
Before using a switching hub (such as Spanning Tree Protocol or Domain
Separation) that supports the function for preventing undesirable loops, be sure to
first suppress this loop-prevention function by either disabling the Spanning Tree
Protocol on the port for connecting the switching hub to this unit, or by setting the
Domain Separation switch to on.
(3)
Time synchronize function
l
Time information in the main unit is synchronized to the time information in the
SMC using the NTP. If the SMC is not active, the OS uses the time information in
the main unit as the default value on boot-up process.
l
Time information on the SMC is under control of the OS on the SMC. Workloads
on the SMC can cause delay. Since time in the main unit is synchronized to time in
the SMC, the time information in the SMC should be adjusted to the correct time
regularly.
(4)
Console paths
Console paths enable the console functions of the partitions by connecting the
RS232C ports on the system boards and the SMC through the multiport console
connection unit.
For details, see
Chapter E.1.4, "On-board serial interface."
(5)
System console software
The system console software for controlling the main unit is preinstalled in the
PRIMESTATION or PW250SMC, which are used by Fujitsu Siemens Computers as
standard SMCs.
If you use an other workstation (e. g. a PRIMEPOWER200) as SMC, for the
installation of the system console software, see Section “SMC Software Installation
Flow”, in the “PRIMEPOWER HPC2500/2500/1500/900 Installation Guide”
(U41300-J-Z816-x-76/C120-E162EN). This description is not applicable to the
PRIMESTATION and the PW250SMC.
