Powering On the 3494

1. Press the Unit Emergency switch (on the operator panel) to the On position (if it
is not already in the On position).
Notes:
a. The library must be powered off and remain off for 30 seconds before you
attempt to power the library on again. The 30-second wait is needed to
allow the 3490E tape subsystem sufficient time to properly initialize.
b. If the 3494 Library has more than eight frames, or the high availability model
is installed, both unit emergency switches must be set to the On position.
The second switch is located at the right-hand end of the Library (when
facing the cartridge access doors).
c. If the 3494 Model B18 VTS is installed, the unit emergency switch on the
Model B18 must be set to the On position.
2. Press the Unit Power switch, on the operator panel, to the On position.
Notes:
a. If the remote power feature is installed and the Local Remote switch is in
the Remote position, the Unit Power switch cannot power on the 3494.
b. When the Rack Power Ready and Power System Ready LEDs are lit, the
power to the library is on.
3. If the library is attached to an AS/400, ensure the media library device driver is
initialized.
4. Ensure all drives are varied Online to the appropriate host.
