Internal Diagnostic LEDs

The system has the following internal fault LEDs to help with identifying a failing component:

• Each chassis fan module has a fault LED on top of the module. These fan LEDs operate only when the

system is in standby power mode.

Maintaining the Server

Internal Diagnostic LEDs

• The CPU module has internal fault LEDs for CPUs and DIMMs on the CPU module board. POST and

runtime error detection routines are stored in on-board registers. The contents of the registers are preserved

for a limited time by a supercap voltage source.

To operate the LEDs, press switch SW1 on the board after the CPU module is removed from the chassis.

DIMM fault LEDs (one next to each DIMM socket

on the board)

• Amber—DIMM has a fault.

• Off—DIMM is OK.

SW1 is labeled, " PRESS HERE TO SEE

FAULTS".

Preparing For Component Installation

This section includes information and tasks that help prepare the server for component installation.

Maintaining the Server

Preparing For Component Installation

Required Equipment For Service Procedures

The following tools and equipment are used to perform the procedures in this chapter:

• T-30 Torx driver (supplied with replacement CPUs for heatsink removal)

• #1 flat-head screwdriver (supplied with replacement CPUs for heatsink removal)

• #1 Phillips-head screwdriver (for M.2 SSD replacement)

• Electrostatic discharge (ESD) strap or other grounding equipment such as a grounded mat

Shutting Down and Removing Power From the Server

The server can run in either of two power modes:

• Main power mode—Power is supplied to all server components and any operating system on your drives

can run.

• Standby power mode—Power is supplied only to the service processor and certain components. It is safe

for the operating system and data to remove power cords from the server in this mode.

After a server is shut down to standby power, electric current is still present in the server. To completely

remove power, you must disconnect all power cords from the power supplies in the server, as directed in the

service procedures.

You can shut down the server by using the front-panel power button or the software management interfaces.

Caution

Shutting Down Using the Power Button

Step 1 Check the color of the Power button/LED:

• Amber—The server is already in standby mode and you can safely remove power.

• Green—The server is in main power mode and must be shut down before you can safely remove power.

Step 2 Invoke either a graceful shutdown or a hard shutdown:

To avoid data loss or damage to your operating system, you should always invoke a graceful shutdown of the

operating system.

Caution

• Graceful shutdown—Press and release the Power button. The operating system performs a graceful shutdown and

the server goes to standby mode, which is indicated by an amber Power button/LED.

• Emergency shutdown—Press and hold the Power button for 4 seconds to force the main power off and immediately

enter standby mode.

Step 3 If a service procedure instructs you to completely remove power from the server, disconnect all power cords from the

power supplies in the server.

Removing the Server Top Cover

Step 1 Remove the top cover:

a) If the cover latch is locked, use a screwdriver to turn the lock 90-degrees counterclockwise to unlock it.

b) Lift on the end of the latch that has the green finger grip. The cover is pushed back to the open position as you lift

the latch.

c) Lift the top cover straight up from the server and set it aside.

Step 2 Replace the top cover:

a) With the latch in the fully open position, place the cover on top of the server about one-half inch (1.27 cm) behind

the lip of the front cover panel. The opening in the latch should fit over the peg that sticks up from the fan tray.

b) Press the cover latch down to the closed position. The cover is pushed forward to the closed position as you push

down the latch.

c) If desired, lock the latch by using a screwdriver to turn the lock 90-degrees clockwise.

Serial Number Location

The serial number for the server is printed on a label on the top of the server, near the front.

Hot Swap vs Hot Plug

Some components can be removed and replaced without shutting down and removing power from the server.

This type of replacement has two varieties: hot-swap and hot-plug.

• Hot-swap replacement—You do not have to shut down the component in the software or operating

system. This applies to the following components:

• SAS/SATA hard drives

• SAS/SATA solid state drives

• Cooling fan modules

• Power supplies (when redundant as 2+2 or 1+1)
