10.5 Connecting and Disconnecting Cables
V CAUTION!
The power plug must be pulled out!
Read the documentation for the external device before connecting any
cables.
Cables may neither be connected nor disconnected during thunder-
storms.
When disconnecting a cable, always hold it by the plug, never pull on the
wire!
When connecting or disconnecting cables, follow the sequence
described below:
Connecting leads
Ê Switch off all the relevant devices.
Ê Pull the power plugs of all the relevant devices out of their sockets.
Ê Connect all the cables to the server and the storage subsystem. Mark the
cables and make a note of the function of each cable. Always note the safety
instructions in chapter “Important Notes” on page 7.
Ê Connect the power plugs to appropriately properly grounded power outlets.
For rack models make sure that the power cables of the devices are
connected in such a way that a even distribution of power to the three
phases (L1, L2, L3) in the rack is achieved (you can find further information
in the manual for the corresponding rack).
Ê For devices mounted in a rack, secure the cables to the articulated cable
guides with cable ties.
Disconnecting leads
Ê Switch off all the relevant devices.
Ê Pull the power plugs of all the relevant devices out of their sockets.
