Setup Guide

1. Remove the ground cable from the shipping bag and cut it to the desired length. The cable length

must facilitate the proper operation of fault interrupt circuits. Dell Networking recommends using the

shortest cable route allowable.

2. To attach the ground cable, use one of the following:

• Using one threaded M3 hole, attached the ground cable to the lug using an M3 screw with a

captive internal tooth lock washer, as shown. Torque the screw to 20 in-lbs.

• Using one of the two threaded M4 holes, attach the ground cable to the lug using an M4 screw

with a captive internal tooth lock washer, as shown. Torque the screw to 20 in-lbs.

3. Attach the other end of the ground cable to a suitable ground point such as the rack or cabinet.

Important Points to Remember

The Z9100–ON is designed to support two hot-swappable power supplies with integrated fans that

provide cooling for the chassis.

• The Z9100–ON ships with two power supplies.

• The PSU slides into the slot smoothly. Do not force the PSU into a slot as this action may damage the

PSU or the Z9100-ON chassis.

• The Z9100–ON supports AC and DC power supplies with two air-flow directions (I/O to Utility and

Utility to I/O). The fan airflow direction for the PSUs must be the same.

CAUTION: The Z9100–ON does not support mixing PSU types.

CAUTION: DO NOT mix airflow directions. Both power supplies must use the same airflow

direction (I/O to Utility or Utility to I/O).

WARNING: Do not run the switch using one PSU.

WARNING: 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: To prevent electrical shock, ensure that the Z9100–ON is grounded properly. If you

ground your equipment incorrectly, excessive emissions may result. To ensure that the power

cables meet your local electrical requirements, use a qualified electrician.

NOTE: The Utility panel consists of two slots, PSU1 and PSU2. Insert PSUs in both slots.
