If you are making Fibre Channel connections to N series mezzanine card, connect Fibre Channel cables
from the Fibre Channel ports (1a and 1b) to your storage expansion unit loop or Fibre Channel switch.
Make sure that SFPs are installed and firmly seated in the Fibre Channel ports (1a and 1b) of the
controller node and the In port of the first storage expansion unit in the loop before attaching a Fibre
Channel cable.

Note:

When you order an N3220 storage system without external storage expansion units, two QSFP SAS

cables and an ACP cable are required to enable the multipath high availability configuration. These cables
can be ordered as FC9563. If you order the storage system with external storage expansion units, the
cables come with storage expansion units.

Important: If you are connecting to EXN1000 or EXN4000 storage expansion units:

When using the optional 8 GB FC Mezzanine (FC2030) adapter Fibre Channel ports to connect to
EXN1000 or EXN4000 storage expansion units, the onboard ports must be set to initiator mode. For
more information, see the

IBM System Storage N3150, N3220, and N3240 Hardware and Service Guide

SFPs

must

be used when connecting fiber cables.

Notes:

For SAN systems with quad-port host bus adapters (HBAs), see the

Multipath and Dual-Path Cabling

Information

document on the IBM N series support website:

www.ibm.com/storage/support/nseries/

For required port usage and specifications for optional Mezzanine adapters supported by your N3220
system, refer to the

IBM System Storage N Series Introduction and Planning Guide

Installing the power cables

Use these instructions to install the power cables for the N3220 filer.

Make sure all power supply switches on the N3220 filer and any attached expansion units are in the
Off position.

For all storage systems that are being installed, connect the power cords to all power supply unit
(PSU) power receptacles using power cord retainer clips, making sure to slide the clip all the way
forward on the plug.

Connect the power cords to the power sources, making sure that the two power supplies are
connected to separate AC sources. This ensures redundant power.

Attention:

Do not power on the system at this time.

Note:

The N3220 storage system has no requirement or provision for grounding.

For proper grounding of expansion units, see the

Installation and Setup Instructions

for the expansion

unit.

Setting up and booting the system in Data ONTAP 7-Mode

Use these instructions to set up and boot the N3220 filer.

Make sure the Configuration worksheet from the

Data ONTAP Software Setup Guide for 7-Mode

completed and available for use.

Note:

IBM recommends that you print a copy of this worksheet from the

Data ONTAP Software Setup

Guide for 7-Mode

Check that your system is properly set up. Make sure that the expansion unit IDs and speed
switches are properly set, and that the cabling is correct for your configuration.

Start a console session for each controller module.
