4. Installing a Switch

Figure 4-51 Checking the LED
(1) Control and switching unit
(2) STATUS LED
(3) ACC LED
CAUTION
When the ppupdate command is executed, the Switch restarts
automatically. Do not turn off the Switch until it is restarted (until the
STATUS LED on the control and switching unit changes from blinking
green to constant green). Failure to do so could result in a Switch
failure.
CAUTION
If the ACC LED is lit, the memory card is being accessed. While a
memory card is being accessed, do not remove the memory card or
turn off the power. Doing so might damage the memory card. In
addition, some commands require a certain amount of time after being
entered to finish accessing the card. Make sure that the memory card
is no longer being accessed before removing the card or turning off
the power.
Step 2
Set all power switches on the Switch to OFF.
