Setup Guide

NOTE: To remove the power connector from a DC PSU, squeeze the levers on both sides of the

connector. Doing so disengages the power connector’s clamps. While continuing to squeeze, pull

the power connector from the DC PSU socket.

Installing a Fan Module

1. Remove the fan module from the shipping box.

2. Use the grab handle to slide the module into the switch fan slot.

Figure 11. Install the Fan Module

The fan module is on the left.

CAUTION: DO NOT mix airflow directions. All fans must use the same airflow direction (I/O to

Utility or Utility to I/O).

CAUTION: Check the fans at six-month intervals and replace them as necessary. To accurately

determine replacement intervals, regularly monitor the speeds of the cooling fans.

Installing the QSFP28 Optics

The Z9100–ON has 32 fixed quad small form-factor pluggable (QSFP) optical ports that support both

QSFP+ and QSFP28.

For a list of supported optics, see the Z9100–ON Specification Sheet at www.dell.com or contact your

Dell Networking representative.

CAUTION: ESD damage can occur if the 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 the 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.

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.
