IBM System Cluster 1350, Installation And Service Manual

Chapter 2. Cabinet placement and intercabinet cabling
This chapter provides information about the final placement and intercabinet
cabling of the cluster cabinets, how to install the frame stabilizer foot and outrigger
to support each cabinet, and how to prepare to install a Rear Door eXchanger
Assembly unit.
Minimum service clearances
Several factors influence final cabinet placement. In addition to adequate cable
length and staying within safe floor loading limits for your installation site,
observe the minimum clearances required for service of the racks in the Cluster
1350. You might want to plan for extra space around the racks to allow movement
of racks for service.
Figure 1 shows the clearances needed for servicing a rack in the Cluster 1350. Note
that the service clearances for the sides of the rack are not required for operation,
but only for servicing the PDUs.

When planning the installation of a large cluster and you want to arrange the racks
in several rows, you must maintain a minimum aisle width of 91.4 cm (36 inches)
as shown in Figure 2 on page 14. This will allow enough space for the front and
back covers of the racks to open. An aisle width of 122 cm (48 inches) might be
more appropriate if you want to make sure that you have enough room to move
the rack to gain access to the sides for servicing the PDUs.
