Appendix F. Communication adapters

This appendix describes the PCI adapters and their correct placement. For more
detailed information on the adapters, refer to the hardware installation guide.
The NAS Gateway 300 has a Fibre Channel adapter (Fibre Channel) as standard
feature. The NAS Gateway 300 also has the following optional adapters:
v Alacritech 100x4 Quad-Port Server Accelerated Adapter
v IBM Gigabit Ethernet SX Server Adapter
v IBM PCI Ultra160 SCSI adapter (LVD/SE)
v Alacritech 1000x1 Single-Port Server and Storage Accelerated adapter
v PRO/1000 XT Server Adapter by Intel
v Qlogic 2340 1-port Fibre Channel adapter
v Qlogic 2342 2-port Fibre Channel adapter
v Remote Supervisor Adapter

PCI adapter placement

These sections explain how to determine the correct positions for PCI adapters.

Adapter placement rules

Adapter placement rules guide which adapter to install in a PCI slot. These rules
consist of priority and slot location. Priority is the sequence in which you install the
adapters. Determining the slot location requires eliminating already filled slots and
placing the adapter into the first available slot according to its possible slot
locations. The priority and slot locations are shown in Table 41. To determine the
location of the slots:
1. Arrange the adapters in order, one having the highest priority, using the Priority
2. Place the highest priority adapter into the first available slot location listed in the
3. Repeat step 2 until all adapters are installed.
Example 1: If you are installing a single IBM Gigabit Ethernet SX Server Adapter,
that adapter should be installed in slot 2.
Example 2: If you are installing five adapters—one Qlogic 2340 1-port Fibre
Channel adapter, two IBM Gigabit Ethernet SX Server Adapters, one IBM PCI
Ultra160 SCSI adapter (LVD/SE), and one Alacritech 100x4 Quad-Port Server
Accelerated Adapter— they should be installed in the following slots:
v Slot 1 — Empty
v Slot 2 — IBM Gigabit Ethernet SX Server Adapter
v Slot 3 — IBM Gigabit Ethernet SX Server Adapter
v Slot 4 — Alacritech 100x4 Quad-Port Server Accelerated Adapter
v Slot 5 — IBM PCI Ultra160 SCSI adapter (LVD/SE)
v Slot 6 — Qlogic 2340 1-port Fibre Channel adapter
