Asetek InRackCDU Installation, Operation & Maintenance Guide 6

Important Information
Any failure to observe the guidelines in this manual, and any improper repairs could expose the
user to risks (electric shock, energy hazards and fire hazards) or damage the equipment.
If the CDU Cabinet enclosure has been moved from a cold environment, into a warm data center
condensation may form both inside and on the outside of the machine.
Wait until the CDU Cabinet has acclimatized to room temperature and is absolutely dry before
starting it up. Material damage may be caused to the monitoring system if this requirement is
not met.
Only transport the InRackCDU and CDMs in the original packaging or in packaging that protects
it from impacts and jolts.
The monitoring unit in the CDU Cabinet requires a supply voltage of 100 – 240 V 50/60 Hz. There
are two redundant, hot-swappable power supplies.
This device must only be connected to properly grounded power outlets or insulated sockets of
the rack's internal power supply with tested and approved power cords.
Never connect or disconnect data transmission lines during a storm (risk of lightning hazard).
Make sure that no objects (e.g. jewelry, paperclips etc.) or liquids can get inside the CDU cabinet
(risk of electric shock, short circuit).
In emergencies (e.g. damaged casing, controls or cables, penetration of liquids or foreign
bodies), switch off the server enclosure immediately, remove all power plugs and contact your
sales outlet or customer service team.
In the unlikely event of a spill or leak of coolant from the server liquid loop follow the suggested
spill response procedure listed in Appendix I.
The circuit boards and soldered parts of internal options are exposed and can be damaged by
static electricity. Before handling them, first touch a metal part of the CDU cabinet to discharge
static electricity from your body.
Do not touch the circuitry on boards or soldered parts. Hold the edges of the circuit boards.
For CDU Cabinet installation use a server lift.
