Note:
Cluster Platform Express (CPE) configurations use a cable routing procedure that is specific to
CPE models. Follow the cabling instructions in the Cluster Platform Express Installation Guide.
The cabling tables are specific to:
•
The total number of nodes in the cluster.
• The models of server used as nodes.
• The node format, which determines rack density.
• Other configuration-specific factors, such as:
— Whether the cluster is a bounded or federated design.
— Whether the cluster is a full or constrained bandwidth design.
— The presence of utility racks (UXR).
Use the following procedure to route and connect cables:
1.
During factory integration, all cables are labelled with their origin and destination ports.
2. Chassis might be stacked above each other. Begin cabling at the lowest chassis in the rack.
3. Working upwards through the line boards, dress the cables in the bracket hook that is
adjacent to the line board for each line card as follows :
a.
Route the cables from ports 1 through 6 and ports 13 through 18 to the left side
b. For each line card, route the cables from Ports 7 through 12 and ports 19 through 24 to
the right side.
4. Use hook-and-loop straps to loom the cables into bundles at the sides of the rack, ensuring
that you maintain the minimum bend radius.
5. When cabling federated ISR 9024 interconnects together, use the following procedure:
a.
Route and bundle the interconnect-to-node cables together so that the main bundle
exits the bottom left of the rack.
b. Cable the federated (leaf-to-spine) interconnects together using cables of 0.5 metre and
1 metre length. These cables do not require mechanical cable management support.
c. Route the short cables up the right side of the rack.
d. A typical cabling example of the federated cabling for four interconnects is shown in
the following table:
Uplink Ports Downlink Ports
7–12 1–6
9–24 13–18
e. Cabling plates with hook-and-loop straps are fastened to the side of the rack to support
the interconnect-to-node cable bundles.
7.1.5 Cable Routing Procedure for the ISR 9096
Refer to the appropriate cabling tables for your model of HP Cluster Platform. The cabling tables
define the syntax of the port names for origin and destination ports. Every port has a unique
designator to ensure correct cabling. The cabling tables are specific to:
•
The total number of nodes in the cluster.
• The models of server used as nodes.
• The node format, which determines rack density.
• Other configuration-specific factors, such as:
