Chapter 5
Maintaining the Server
This chapter describes how to replace components in the Sun Cobalt™ LX50 server after it has been set up. It
contains the following sections:
• “Tools and Supplies Needed” on page 5-2
• “Determining a Faulty Component” on page 5-2
• “Safety: Before You Remove the Cover” on page 5-2
• “Removing and Replacing the Cover” on page 5-3
• “Customer Replaceable Unit (CRU) Procedures” on page 5-4
• “Field Replaceable Unit (FRU) Procedures” on page 5-15
✍
Note : The procedures in this chapter for servicing field replaceable faulty components are for
the attention of qualified service engineers only. If a Field Replaceable Unit (FRU) needs
replacement, contact your local Sun Sales representative who will put you in contact with the
Sun Enterprise Service branch for your area. You can arrange to return the system to Sun for
repair under the terms of your warranty. Or, if under a Sun Service agreement, the FRU will be
replaced by a Sun Service engineer. If a Customer Replaceable Unit (CRU) needs replacement,
you can either request a replacement part from Sun or return the entire unit for repair. All parts
replaced under the system warranty must be returned to Sun within 30 days of receipt of the
replacement part.
✍
Note : When working on a server, you may want to turn on the blue System ID LED to identify
the server that is being worked on. See “LEDs” on page 3-2 for instructions on how to turn on
this LED.
