CAUTION:
If a 2104 Model DS4 is fully loaded with 14 drives and two power supplies, its
total weight exceeds 32 Kg (70.5 lbs). You must remove at least six drives from
the 2104 Model DS4 before you lift it or install it into a rack or 2104 Model TS4.
This reduces the total weight to less than 32 Kg (70.5 lbs) and the
can then be safely handled by two people. Failure to do so can result in
DS4
2104 Model
injury.
Attention:
If you have data stored on the drives, label the drives before you remove
them. When you replace the drives, install each one in the same drive bay
from which you removed it. Failure to do so could result in a loss of data.
A standby condition is indicated by the symbol to the right of the DC
