When installing new hardware, such as a NetApp HA pair and two DS224C shelves, into an existing, populated rack, a site survey must confirm fundamental physical requirements. First, it is essential to verify that there are sufficient contiguous Rack units (U) available to physically mount the new controllers and shelves. The DS224C shelf, for example, requires 2U of space. Second, adequate Power connections must be available from the rack's Power Distribution Units (PDUs), and the existing power infrastructure must be able to support the additional load from the new equipment. These two factors, space and power, are critical prerequisites for a successful hardware deployment.

A. Cluster switch location: The scenario specifies a "switchless" HA pair, which by definition does not use cluster interconnect switches, making this verification irrelevant.

D. Crash cart location: A crash cart is a mobile tool for initial setup or console access; its location is a minor logistical convenience, not a fundamental installation requirement.

Section: "Step 1: Prepare your site". This guide

applicable to systems that can be deployed in a switchless configuration

explicitly lists verifying rack space and power as primary site preparation tasks. It states

"Verify that your rack has enough space for the equipment..." and "Verify that you have the required power...".

2. NetApp Hardware Universe (hwu.netapp.com)

Specifications for DS224C Disk Shelf. The official specifications confirm that a DS224C shelf occupies 2U of rack space and details its specific power consumption requirements

underscoring the need to verify both rack units and power capacity during a site survey.

3. NetApp Universal SAS and ACP Cabling Guide

Section: "Cabling a two-node switchless cluster". This document illustrates the physical connectivity but implicitly relies on the pre-deployment assumption that rack space and power for all components have been properly planned and verified. The physical placement shown in diagrams requires available rack units.
