18 IBM System p5 520 and 520Q Technical Overview and Introduction
1.5.7 Rack-mounting rules
The primary rules that you should follow when you mount the server into a rack are:
The p5-520 or p5-520Q is designed to be placed at any location in the rack. For rack
stability, we advise that you start filling a rack from the bottom.
Any remaining space in the rack can be used to install other systems or peripherals,
provided that the maximum permissible weight of the rack is not exceeded and the
installation rules for these devices are followed.
Before placing or sliding a p5-520 or p5-520Q into the service position, it is essential that
you have followed the rack manufacturer’s safety instructions regarding rack stability.
The availability of 14-foot, 9-foot, and 6-foot jumper cords (between the drawer and the PDU)
provides several options to ensure that all cables are accounted for inside the rack space.
Depending on the current implementation and future enhancements of additional 7311 Model
D20 drawers that are connected to the system, Table 1-12 shows examples of the minimum
and maximum configurations for different combinations of servers and attached 7311 Model
D20 I/O drawers.

This section highlights some solutions available to provide a single point of management for
environments composed of multiple p5-520 or p5-520Q servers or other IBM System p5
servers.
