IBM TotalStorage SAN Volume Controller: Installation Guide
Attention: If a SAN Volume Controller is powered off for more than five minutes
and it is the only SAN Volume Controller that is connected to an uninterruptible
power supply (UPS) 5125, the UPS 5125 also powers off. To power on the SAN
Volume Controller, you must first power on the UPS 5125 to which it is connected.
Note: The UPS 5115 will not power off when the SAN Volume Controller is shut
down from the power button.
The green power LED indicates the power status of the SAN Volume Controller:
The properties of the green power LED are as follows:
Off
v One or more output voltages from the power supply are not present.
On
v All the output voltages from the power supply are present.
Blinking
v The service controller, which provides the graphics and text for the front panel
display, is in standby mode. (The rate of blinking is 0.5 seconds on, 0.5 seconds
off.)
This is an amber LED used to indicate critical failures on the service controller.
If the check LED is off and the power LED is on, the service controller is working
correctly.
If the check LED is on, a critical service controller failure has been detected.
The check LED is also on while the service controller code is being reprogrammed.
For example, when the SAN Volume Controller cluster code is being upgraded, the
check LED will be on. It is normal for the check LED to be on at this time.
Use the navigation buttons to move through menus.
There are four navigational buttons that you can use to move throughout a menu:
up, down, right and left.
Each button corresponds to the direction that you can move in a menu. For
example, to move right in a menu, press the navigation button that is located on the
right side. If you want to move down in a menu, press the navigation button that is
located on the bottom.
Use the select button to select an item from a menu.
The select button is located on the front panel of the SAN Volume Controller, near
the navigation buttons.
