Chapter 2 System Installation with the Content-
Server 4000 Series
IMPORTANT: The ContentStore 5840 must be grounded before applying power.
The plug on the power supply cord is used as the main disconnect device. Ensure that the socket
outlets are located near the equipment and are easily accessible.
CAUTION: When powered by multiple AC sources, disconnect all supply power for complete isolation.
CAUTION: Do not remove covers from the ContentStore 5840 or any of the modules – there is a danger
of electric shock inside. Do not attempt to disassemble the rear sub-chassis from the ContentStore 5840.
Return any damaged components to your supplier for repair.
CAUTION: The PSUs contain double pole/neutral fusing. Ensure that your electrical installation can
support this.
IMPORTANT: The optional RJ45 socket on the I/O module is for Ethernet connection only and must not
be connected to a telecommunications network.
Regional Safety

Operating Safety
IMPORTANT: All rear modules are part of the fire ContentStore 5840 and must only be removed when a
replacement can be immediately inserted.
IMPORTANT: The ContentStore 5840 will not receive sufficient airflow or cooling if it is operated with
any of the rear modules missing. It is essential that every module bay is filled either with a module or a
blank module.
Replace any defective module with a fully operational unit as soon as possible. Do not remove
cooling modules, PSUs or I/O modules unless you have a replacement model of the correct
ready for insertion.
CAUTION: To prevent overturning, drawer interlocks stop users from opening both drawers at the same
time. Do not attempt to force open a drawer when the other drawer in the ContentStore 5840 is already
open. In a rack containing more than one ContentStore 5840, do not open more than one drawer per rack
at a time.
CAUTION: Operating temperatures inside the ContentStore 5840 drawers can reach up to 60°C. Take
care when opening drawers and removing drive carriers.
CAUTION: Due to product acoustics it is recommended that users wear ear protection for any prolonged
exposure.
