Since the chassis weight with all the HDDs installed is over 100kg, it requires two more
persons to lift with suitable tools.
Before You Start
To reduce the risk of injury from electric shock, remove the power cord to completely
disconnect power from the system.
Moving the Power On/Off switch to the Off position does not completely remove power
from the system. Some portions of the power supply and some internal circuitry remain
active. Disconnect all power cords from the server to completely remove power from
the system.

2.7 System Fans
Subdividing the SIM board area and the backplane area is a metal cage that holds the system
fans. This server contains 12 system fans which are located inside the chassis. These system
fans maintain the ideal temperature for the SIM boards, backplanes and disk drives.
The sequence of system fans is shown below for your reference:

Before you Begin
Before removing the chassis cover, disconnect all power. Unplug the AC power
Make sure you have a stable, clean working environment. Dust and dirt can get into computer
components and cause a malfunction. Many of the screws on the server are different sizes;
use containers to keep screws and small components separated.
Adequate lighting and proper tools can prevent you from accidentally damaging internal
components. Most of the following procedures require only a few simple tools, including the
following:
cord; disconnect all peripherals, and all LAN lines.
Philips screwdriver
flat-tipped screwdriver
set of jewelers screwdrivers
grounding strap
anti-static pad
Troubleshooting Sequence
Installation Problem
Perform the following checks if you are troubleshooting an installation problem:
Check all cable and power connections (including all rack cable connections).
Unplug the power cord, and wait one minute. Then reconnect the power cord and try
again.
Remove all added options, one at a time, and try to power up the system. If after
removing an option the server works, you may find that it is a problem with the option or
a configuration problem between the option and the server. Contact the option
vendor for assistance.
If the system doesn’t power on, check the LED display. If the power LED is not on, you may
not be receiving AC power. Check the AC power cord to make sure that it is securely connected.
Troubleshooting External Connectors
Loose or improperly connected cables are the most likely source of problems for the system,
monitor, and other peripherals (such as a printer, keyboard, mouse, or other external device).
Ensure that all external cables are securely attached to the external connectors on your
system. See 1.1 System Overview for the front- and back-panel connectors on your system.
Troubleshooting System Boot Issues
This document lists troubleshooting tips if your server does not boot up properly.

System Does Not Boot up at First Integration
Board-to-Board Power Connector Not Plugged In
Check the connection between the SIM board and the docking board, and the connection
between the docking board and the middle plane. If one of them is not connected fully in place,
the system will not boot up. Please ensure that they are fully connected.
Power Supply and Chassis Issues
No boot situations can be caused by any of the following power supply, chassis or fan issues:
Verify that your chassis and power supply is appropriate for the frequency and the SIM
boards you have.
Verify that the power supply has the capacity to power all the devices used in your
system.
Ensure the power cord is firmly connected to the power supply and the AC outlet.
If the power supply or the AC outlet has an on/off switch, make sure that it is on.
Cable Issues
No boot situations can be caused by any of the following cabling issues:
Make sure the drive ribbon cables inside the computer are attached correctly and
securely.
Check that the cables connecting the chassis back panel to the SIM boards are
plugged in properly to the onboard headers.
Electrical Short or Overload
An electrical short or overload may cause a system not to boot.
Check for shorts and overloads by removing non-essential items such as extra controller
cards. Keep only the SIM boards, power supply installed. If the system boots, it is possible
there is a short or overload with one of the components that you removed or one of those
components is faulty. Replace each of non-essential items one at a time until you isolate
which one is causing the problem.
Page 30
Appendix
If the problem occurs even after removing the non-essential components, the problem has to
be with the SIM boards, power supply.
System Used to Boot up and Now Does Not
Changes to your computer's configuration can cause your system to not boot properly.
New Drive was Installed
If you added a new drive and now the system won't boot:
Make sure the new drive is supported for your SIM boards. To find the tested hard
drive list for your board, please contact your field representatives.
Make sure all drive cables are properly connected.
Make sure the correct power cable is connected to the new drive.
Make sure other devices and cables inside the chassis were not disturbed or loosened
when you added the new drive.
Examples of troubleshooting system boot issues
Below are some examples on how to troubleshoot system boot issues.
Fans don’t spin when power button pressed
Is at least one power supply fan spinning?
If it is yes, there is good power to the modules. Verify all required power cables are
correctly plugged into the SIM boards. Verify back panel cables are fully seated.
If it is no, there is potential lack of clean power to the module. Swap power cable. Try
different wall circuit or port on UPS.
