CHAPTER 2
Operations of SV8500 Server
To perform the ACT/STBY system changeover, check the lamp indicators shown in Figure 2-9, and
then operate the related key.
Note:
LED indications cited in Figure 2-9 are only an example. The indicating pattern (ON/Flash/OFF) can
differ, depending on each system setting.
Note:
If both ACT lamps (SYS0 and SYS1) light green because of reasons such as ACT-CPU failure, the system
whose LINK lamp is lighting green is ACT side.
The following illustrates the mounting location of each card in TSWR.
