What to Do

To set up the split backplane dual-loop configuration, complete the following steps:
Caution – Printed circuit boards contain electronic components that are extremely
sensitive to static electricity. Ordinary amounts of static from your clothes or the
work environment can destroy components. Do not touch the components or any
metal parts without taking proper antistatic precautions. When performing the setup
instructions, place the PCI Dual FC Network Adapters on an antistatic surface and
use an antistatic wrist strap.
1. Set the OpenBoot configuration variable auto-boot? to false.
2. Power off the server.
3. Remove the primary and secondary I/O fan tray assemblies.
See "How to Remove an I/O Fan Tray" on page 76
4. Disconnect the following cables (if installed) from the expansion backplane and
the base backplane:
For cable connector locations, see
Locations" on page
a. Base/expansion cable from base and expansion backplane connector J0801.
b. FC-AL data cable (Loop B) from base backplane connectors J01103 and J01102
and from expansion backplane connectors J01101 and J01100.
c. FC-AL data cable (Loop A) from expansion backplane connectors J0201 and
J0200 and from base backplane connectors J0501 and J0500.
5. Choose the slots for the PCI Dual FC Network Adapters.
For easy cable routing, plan to install two of the PCI Dual FC Network Adapters in
any two of PCI slots 0 through 6 and the other network adapter in PCI slot 7 or 8.
Installing the network adapters in these slots enables you to route all three cables
along the floor of the I/O compartment. See
page 296.
6. Install the three PCI Dual FC Network Adapters.
See "How to Install a PCI Card" on page 83
Each PCI Dual FC Network Adapter contains two external optical transceiver
connectors, located on the spine of the adapter. Pull the dust cover from each
external connector before you install the adapters.
After you install the network adapters, replace the dust covers on the Port 1
connectors. In this configuration, Port 1 of the network adapters cannot be used to
connect to external devices. Use only Port 2 to connect to external devices.
