Connecting The Cables; Gb Ethernet Cabling; High-Speed (Myrinet) Switch Cabling - IBM eserver Cluster 1350 Installation And Service Manual

Connecting 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 identifies the device or
node it connects to, and where applicable, its port number.
Depending on the country of manufacture the label scheme will vary. Before you
begin attaching cables, become familiar with the information on the labels.
When installing a Cluster 1350, start with the primary cabinet. After you have
connected the intracabinet cables inside the primary cabinet, move on to each
expansion cabinet and use the information printed on each cable label to connect
the cables in the cabinet.
After you have connected any cables in the primary cabinet and expansion
cabinets, connect the cables that run between the cabinets. This is called the
intercabinet cabling, and the following types of cables are involved:
v 1 Gb 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 see the Cluster
1350 information on the IBM InfoTips Web site:
http://w3.pc.ibm.com/helpcenter/infotips/. The information is also available in the
IBM Current Object Repository (CORE) system.
The following sections describe the different types of cabling.

1 Gb Ethernet cabling

The 1 Gb Ethernet provides a high-speed optical trunk line for VLAN
communication with the management node.
Each intercabinet cable has labels at both ends. You can use the information on the
label to create a site map to document all cable routing.

High-speed (Myrinet) switch cabling

The Myrinet high-speed switch provides an optional 2 Gb optical network for
communications between cluster nodes and storage nodes.
Each intercabinet cable has labels at both ends. You can use the information on the
label to create a site map to document all cable routing.
