Pathlight VX Site Preparation Guide 21

• The rack must have a 4 ft. clearance at the front and the rear to install, cable, and service the

Pathlight VX components. If the rack has removable side panels, there should be a 4 ft. clearance

on the sides.

• The Pathlight VX Controller, consisting of the Management Server (MS), storage network controller

(SNC), and, in some configurations, the FC switch, must be installed at 26-to-30 rack units height

in a Pathlight VX-650. In a Pathlight VX-450, the Pathlight VX Controller must be installed in 4

contiguous rack unit space (to accommodate the Pathlight VX bezel).

Table 12

lists the rack space requirements for each Pathlight VX configuration. In the left column, locate the

Pathlight VX configuration that will be installed at the customer site, and reserve the required amount of rack

space for the system. All Pathlight VX-650 configurations (24 total) require a minimum of 30 contiguous rack

units for installation, although the actual rack units occupied by the components may be less, as shown in

the “Actual Units of Required Rack Space” column. It is a best practice to keep open space for adding

additional components in the event of an upgrade, and to maintain product consistency with respect to the

vertical placement of the bezel and company trademark.

In the Pathlight VX-650, the Pathlight VX Controller must be installed at 26-to-30 rack units height, which

creates open space between the Pathlight VX Controller and the disk enclosures in many of the Pathlight

VX-650 configurations. The open rack space between the Pathlight VX Controller and the disk enclosures

explain the need for the “Actual Units of Required Rack Space” column.
