System component replacement

The field-replaceable units for the S3400-family server vary depending on the model as follows:

• Message Storage Server (standard or high-availability configuration)
• Messaging Application Server

Message Storage Server (MSS) components

The Message Storage Server (MSS) is offered in two configurations: standard (MSS-S) and high-availability (MSS-H). A slightly different set of components can be replaced on either model.

For either model, the following components can be replaced on site:

• Circuit cards:
  • Network interface card (NIC)
  • Remote maintenance board (RMB)
  • MSS-H only: SCSI RAID controller board
  • Video card
• Internal cables including:
  • Disk drive cables
  • Other internal cables including fan power, LED panel, RMB reset cable, and (on MSS-H only) the SCSI cable group
• DVD-RAM drive
• Fans
• Memory module

For component replacement unique to each model, see:

• MSS-S replaceable units
• MSS-H replaceable units

If any other internal components fail, such as the motherboard or the SCSI drive backplane, then the entire machine must be replaced. See Machine replacement for this procedure.

MSS-S additional replaceable units

The following additional components can be replaced on site:

• IDE RAID drives
• Standard power supply

MSS-H additional replaceable units

The following additional components can be replaced on site:
