Attaching The Ground Cable (Optional); Install The Sfp+ Optics - Dell Z9100-ON Installation Manual

NOTE: Do not the use the mounted ReadyRails as a shelf or a workplace.

Attaching the Ground Cable (Optional)

To attach the ground cable to the chassis, use a single M4x0.7 screw. The cable itself is not included with
the Z9100–ON system.
To properly ground the chassis, Dell Networking recommends using a 6 AWG one-hole lug, #10 hole
size, 63" spacing (not included in shipping). The one-hole lug must be a UL recognized, crimp-type lug.
CAUTION: Grounding conductors must be made of copper. Do not use aluminum conductors.
NOTE: The rack installation "ears" are not suitable for grounding.
NOTE: Coat the one-hole lug with an anti-oxidant compound prior to crimping. Also, bring any
unplated mating surfaces to a shiny finish and coat with an anti-oxidant prior to mating. Plated
mating surfaces must be clean and free from contamination.
To connect the ground cable to the system, follow these steps.
1. Cut the ground cable to the desired length. The cable length must facilitate proper operation of the
fault interrupt circuits. Dell Networking recommends using the shortest cable route allowable.
2. Take the one M4x0.7 screw from the package.
3. Attach the one-hole lug to the chassis using the supplied 10-32 screw with the captive internal tooth
lock washer. Torque the screw to 20 in-lbs.
4. Attach the other end of the ground cable to a suitable ground point. The rack installation "ears" are
not a suitable grounding point.

Install the SFP+ Optics

The Z9100–ON has two SFP+ optical ports.
For a list of supported optics, see the Z9100–ON specification sheet at
your Dell Networking representative.
CAUTION: ESD damage can occur if components are mishandled. Always wear an ESD-preventive
wrist or heel ground strap when handling the Z9100–ON and its components.
WARNING: When working with optical fibers, follow all warning labels and always wear eye
protection. Never look directly into the end of a terminated or unterminated fiber or connector
as it may cause eye damage.
To install SFP+ optics into an open port, follow these steps:
1. Position the optic so it is in the correct position. The optic has a key that prevents it from being
inserted incorrectly.
2. Insert the optic into the port until it gently snaps into place.
NOTE: When you cable the ports, be sure not to interfere with the airflow from the small vent
holes above and below the ports.
