Node identification label
The node identification label on the front panel displays a six-digit node
identification number.
The node identification label is the same as the six-digit number that is used in the
svctask addnode command. It is readable by system software and is used by
configuration and service software as a node identifier. The node identifier can also
be displayed on the front panel display when node is selected from the menu.
If the service controller assembly front panel is replaced, the configuration and
service software displays the number that is printed on the front of the
replacement panel. Future error reports contain the new number. No cluster
reconfiguration is necessary when the front panel is replaced.
Product serial number
The node contains a SAN Volume Controller product serial number that is
imbedded on the system board hardware.
This number is used for warranty and service entitlement checking and is included
in the data sent with error reports. It is essential that this number is not changed
during the life of the product. If the system board is replaced, you must follow the
system board replacement instructions carefully and rewrite the serial number on
the system board.
Cache LED
System activity is indicated through the green, cache LED.
See Table 1 for the system activity indicators.
Table 1. Cache LED settings
Cache LED status Result
Off The system has not yet started processing.
On The system is functionally active, has joined a working
cluster, and is processing data.
Flashing The node is dumping cache data in anticipation of a system
reboot (from a pending power down or other controlled
restart sequence). Do not remove the power cable or force a
power-off while this LED is flashing.
Power button
The power button switches on or off, the main power to the SAN Volume
Controller.
To turn on the power, press and release the power button.
To turn off the power, press and release the power button.
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 2145
uninterruptible power supply (2145 UPS), the 2145 UPS also powers off. To power
on the SAN Volume Controller, you must first power on the 2145 UPS to which it
is connected.
