Remove The Sfp+ Optics; Power Up The System; Power Up Sequence - Dell Z9100-ON Installation Manual

Remove the SFP+ Optics

Remove an optic by pushing the tab on the optic and sliding the optic from the port.
When removing optics with direct attach cables (DACs) from the port, pull the release tab firmly and
steadily. Prior to pulling the release tab, you may need to gently push the optic into the port to ensure
that it is seated properly. Do not jerk or tug repeatedly on the tab.

Power Up the System

Supply power to the Z9100–ON after it is mounted in a rack or cabinet.
Dell Networking recommends re-inspecting your system prior to powering up. Verify the following:
• The equipment is properly secured to the rack and properly grounded (optional).
• The equipment rack is properly mounted and grounded (optional).
• The ambient temperature around the unit (which may be higher than the room temperature) is within
the limits specified for the Z9100–ON (see Specifications).
• There is sufficient airflow around the unit.
• The input circuits are correctly sized for the loads and that you use sufficient over-current protection
devices.
• All protective covers are in place.
• Blank panels are installed if you do not install optional modules.
NOTE: A US AC or DC power cable is included for powering up an AC or DC power supply. You
must order all other power cables separately.
NOTE: ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist
or heel ground strap when handling the Z9100–ON system and its components.

Power Up Sequence

When the system powers up, the fans immediately come on at high speed. The fan speed slows as the
system continues to boot up.
