Overview of the field replaceable units

Identification and description of units

The filers in the NetApp F700 series are designed for easy access so that you can remove and install units in the field. You can gain access to the units from the front or back panel. Except for system memory modules and disks drives, you must purchase all field replaceable units from Network Appliance.

Units that you can individually replace

You can replace the following units in the NetApp F700 series in the field:

Motherboard (with removable DIMMs [dual in-line memory modules], lithium battery, and CPU cooler fan)
Expansion adapters
- NVRAM (nonvolatile random access memory) adapter (with removable SIMMs [single in-line memory modules] and lithium batteries)
- SCSI adapters for disk storage
CPU fan
3.5-inch diskette drive subassembly
Power supply
LED/LCD subassembly
Chassis fan subassembly

Units that you cannot individually replace

You cannot replace the following onboard interfaces on the motherboard:

10/100Base-T Ethernet interface
FC-AL (Fibre Channel Arbitrated Loop) interface
SCSI tape interface

If you have problems with any of these interfaces, you need to replace the motherboard.

Units that you can optionally add

You can optionally add the following units in the NetApp F700 series in the field:

Additional FC-AL adapters for fibre channel disk storage
Additional network interface cards/adapters (NICs)
Additional SCSI adapters for SCSI disk storage
Additional SCSI adapter for a second tape drive for the F760 (Requires Data ONTAP^TM 5.3 software or later.)
Additional power supply for the F720

Units accessible from the filer front

A plastic bezel covers the front panel of the filer. You can remove the bezel to get access to the chassis fan subassembly, the LED/LCD subassembly, and the diskette drive subassembly. The following figure shows the replaceable units accessible from the filer front panel.

Units accessible from the filer back

You can gain access to the following units from the back of the filer:

Power supplies
PCB (printed circuit board) carrier, a slide-mounted tray that serves as the mounting base for the motherboard

You can pull out the PCB carrier from the chassis for access to the motherboard and the expansion adapters. The following figure shows the replaceable units accessible from the back of a filer with an AC power supply.

The following figure shows the replaceable units accessible from the back of a filer with a DC power supply.
