2. If you purchased an expansion node, rack and cable the expansion node(s) before moving
to the next step.
a. Add expansion nodes to the rack by following the HP StorageWorks 2U Storage System
Rail Kit Installation Instructions, packaged with the rail kit.
b. Cable the expansion nodes to the messaging system chassis. For recommended cabling,
see “Install E5000 expansion nodes” (page 16).
3. Cable the messaging system to your network and attach the power cords. See “HP E5000
Messaging System rear view” (page 8) for connecting ports. For information on network
configurations, see “Preparing to install the messaging system” (page 9).
Install E5000 expansion nodes
IMPORTANT: If you order optional expansion nodes, be sure to rack and cable them to the
messaging system before powering on for initial configuration.
Install the hardware and cabling
To install the hardware and cabling:
1. Cable the additional expansion nodes to your messaging system.
2. Rack the expansion nodes.
For instructions, see the HP Rail Kit Installation Instructions.
3. Cable the additional expansion nodes to your messaging system.
IMPORTANT: Ensure that cabling in the back of the rack system does not interfere with system
operation or maintenance. Bind cables loosely with cable ties and route the excess out of the way,
along the side of the rack, to keep system components and indicators easily visible and accessible.
