Site Planning
The procedures in this guide assume the use of one system console.
Site Planning
The physical layout of your site affects how easy it is to service and operate your
system.
Changing the number of enclosures in your system might involve many factors at your
site including:
•
Physical layout of the site
•
Access to the room to install more equipment
•
Cooling requirements
•
Power requirements
•
Space issues such as service clearance, or the capacities of cable channels and
cable troughs
Cabling
When you expand a system, you must attach all cables correctly so that added
enclosures can communicate with the rest of your system. When you reduce a system,
you must remove cables correctly so that remaining enclosures can continue to
communicate with each other.
The types of cables you need to consider are:
•
ServerNet cables (discussed in this guide)
•
Power-on cables (discussed in this guide)
•
Ethernet cables (discussed in this guide)
•
AC power cords (discussed in this guide)
•
DC power cables for system enclosures with power shelves
•
Cabling from SCSI ports on PMF CRUs and IOMF CRUs
•
Interface cables for devices attached to ServerNet adapters
•
Fibre Channel cables (to connect FCSAs to Fibre Channel storage devices such
as an Enterprise Storage System (ESS))
