CAUTION:
Rebooting the VLS device places the VLS cartridges back into the same library slots and tape drives they
were in at the time of reboot. To move the cartridges from tape drives back into the appropriate slots, use
Force Unload from the task bar visible when you select the tape drive from the navigation tree.
Powering off the system
WARNING!
To reduce the risk of personal injury, electric shock, or damage to the equipment, remove
the power cord to remove power from the node before removing the access panel. The front panel Power
On/Standby button does not completely shut off system power. Portions of the power supply and some
internal circuitry remain active until AC power is removed.
To power off the system from the VLS CLI:
1. Verify that any backup or restore operation has completed and that the VLS is idle.
2. Open a serial session and log in as the administrator. See Opening a serial session .
3. Initiate a shutdown of the VLS by entering:
shutdownSystem
4. If you will be removing the access panel from a node, wait until the VLS has completed its shutdown
operation, then press the UID LED button. See Front panel LEDs and buttons .
Blue LEDs illuminate on the front and rear panels of the node.
5. Press the Power On/Standby button on all nodes to place the nodes in standby mode.
When a node activates standby power mode, the system power LED changes to amber.

If you will be removing the access panel from a node:
a. Go to the back of the rack and locate the node by identifying the illuminated rear UID LED
button.
b. Unplug the node AC power cords from the power source.
