About HP Fabric Clustering System for InfiniBand
InfiniBand is an industry-standard high-speed, packet-based interconnect for node-to-node communications.
HP Fabric Clustering System for InfiniBand provides higher speed, lower network latency and uses less CPU
than other industry standard protocols (for example, Fibre Channel and Gigabit Ethernet). Instead of using a
traditional bus-based technology, HP Fabric is built around switched fabric architecture, providing the
bandwidth necessary for high speed data transfer. For more information on the InfiniBand standard see
HP’s release of this clustering solution delivers the performance and scalability required by the following:

Install Fabric Switches
This section describes how to install the switch in a standard HP rack.
Chapter 1
Installation Overview & Planning
Installing HP Fabric Clustering System
In addition to the accessories provided with the switch, you should have:
A T-10 Torx driver and a Phillips #2 screw driver.
A second person for the installation.
Rack Mount Preparation
Prior to mounting the switch in a rack:
1. Check the slot in the rack for 1U clearance.
2. Open the box, remove the switch, rail brackets, and parts bag.
3. Place the switch on a secure, clean surface.
4. Open the plastic bag containing mounting parts.and locate:
(12) Torx screws for attaching the rails to the switch
(8) screws and clips for attaching the rails to the rack.
It is highly recommend that two people install the switch, but it can be installed with one,
however it may be difficult to support and align the switch correctly in the rack rails with only
one person.
Installing the Switch
Step 1. Take one set of sliding brackets and separate them. Each side arrives with the sliding rail
assembled to a fixed rail. They need to be separated prior to attaching to the switch.

Step 2. To install the switch with the bezel to the front of the rack, install with the flange at the front of the
switch. You can also mount the flange toward the back if you want to mount the switch backward in
the rack such that the service-side is forward.
Attach the rail with 6 screws to each side of the switch in the locations shown in Figure 1-7
Chapter 1
Installation Overview & Planning

Figure 1-8 Attach Rail to Switch
Step 3. Repeat steps Steps 1 and 2 on the other side of the switch.
The two sliding rails should still be unattached.
Step 4. Loosely attach the switch with one screw through the front of each rail.
Temporarily support the switch until the sliding rails are attached.
Figure 1-9 Loosely Attach Rail to Rack
Do not let the switch hang unsupported from only the fixed rail flanges.

Installation Overview & Planning
Installing HP Fabric Clustering System
Attach Cable Guides & Cables
The Fabric cables are high performance impedance-controlled cables with protective shielding, and due to the
thickness and stiffness of the cables, HP recommends that Cable Guides be installed prior to attaching cables
to minimize stress on the connectors for both switch and HCA cabling.
The Fabric cables should be securely attached to the rack enclosure. HP recommends the use of the included
E7723-60003 Cable Guide Installation Kit mounted in a horizontal fashion as depicted below in Figure 1-13.
A second Cable Guide is included and it can be installed in the horizontal or vertical position to better guide &
support the cables for either the switch or HCA. Cable Guide Installation Instructions are provided as a
separate document included with the Cable Guides.
Figure 1-13
Cable Guide with Cables
Attach Cables
The connectors include a latching mechanism. The latching and unlatching mechanism varies by
manufacturer, and prior to installing cables, familiarize yourself with how to engage and disengage the latch.
Attach cables to switches and HCAs assuring that the latch is engaged on each connection.
Do not attempt to make sharp bends or folds in the cables. Care should be taken such that the mounting of
the cable to switch or adapter does not place unnecessary stress on the connection as depicted below:

Installing HP Fabric Clustering System
On-Line Addition and Replacement Operations (OL*)
On-Line Addition and Replacement (OL*) of HP Fabric adapters is supported on HP Fabric Clustering
System version B.11.23.02 with a couple of limitations related to replacing an HCA, see below.
Replacing an HP Fabric Clustering System HCA
Do Not use an Attention Button to REPLACE an HP Fabric HCA.
Do not use the Attention Button method of On-Line Addition and Replacement (OL*) to replace an existing
HP Fabric Clustering System HCA, as the slot will not power off. Use the Command Line Interface, or
Peripheral Device Tool graphical user interface (GUI) to replace an HP Fabric HCA. Refer to the Interface
Card OL* Support Guide, available on http://www.docs.hp.com for details on using standard OL* features.
To replace an HCA using the command line, you must use option olrad -f as in this example:
$ /usr/bin/olrad [-f] -r slot_id
where slot_id is the Slot ID of the slot.
The -f option overrides the “data critical” errors returned by Critical Resource Analysis. It is important to
note that olrad will not allow “critical” errors to be overridden and that olrad automatically overrides
Whether -f is specified or not, critical resource analysis routines are run before an OLA/R operation, to
ensure that the current OLA/R operation does not interrupt the normal working of the system; in other
words, to identify “critical” errors.
The “data critical” errors are typically not critical to the system, but they may be critical to the user. Hence,
the user need to decide whether or not to use the -f option for overriding these types of errors.
HP Fabric HCAs can be added using the Attention Button feature.
