General Information; Attaching The Cables; 1-Gb Ethernet Cabling - IBM Cluster 1350 Installation And Service

General information

Most of the cabling in a Cluster 1350 system will be installed during
manufacturing. There are three instances where cables must be installed at a
customer site:
v Cables between cabinets.
v Replacements for faulty cables.
v Cables to replacement components.
Any cable that fails at the customer site or is connected to components that must
be replaced will need to be reconnected at the customer site.

Attaching the cables

Cables and the cable harnesses in each cabinet are labeled with information that
tells where to connect each end of the cable. Each label will identify the device or
node it connects to, and where appropriate, its port number.
Depending on the country of manufacture the label scheme will vary. Before you
begin attaching cables take some time to familiarize yourself with the information
on the labels.
When initially installing a Cluster 1350 start with the Primary cabinet. Once you
have attached the intracabinet cables inside the Primary cabinet, move on to each
Expansion cabinet and use the information printed on each cable label to properly
attach the cables found there.
Once you have reattached any cables in the Primary cabinet and Expansion
cabinets you can move on to attaching the cables that run between cabinets. This is
called the intercabinet cabling and the following types of cables are involved:
v 1 or 2 GB Fibre Channel (optical)
v 1 GB Ethernet (optical)
v 2 GB Myrinet (optical)
v 10/100/1000 Ethernet (copper)
v KVM (copper)
For a complete listing of all available cables and their part numbers refer to the
Cluster 1350 information contained on the IBM InfoTips web site.The same
information is also available in the IBM Current Object Repository (CORE) system.

1-GB Ethernet cabling

The 1-GB Ethernet provides a high-speed optical trunk line for VLAN
communications with the Management Node. Figure 5 on page 25 schematically
shows a possible intercabinet cabling for a large cluster configuration. VLAN types
1, 3, and 4 would follow this model.
ATTENTION!
All intercabinet cables have labels at both ends of each cable. You can use the information on the label to create a
site map to document all cable routing.
