3. Media tray
Step 4.
For problems that affect only the CD or DVD drive, make sure that:
a.
The CD or DVD is inserted correctly in the drive. If necessary, insert the end of a straightened
paper clip into the manual tray-release opening to eject the CD or DVD. The drive LED flashes
once per second when the CD or DVD is inserted.
b.
The CD or DVD is clean and not damaged. (Try another CD or DVD if you have one.)
c.
The software program is working properly.
Step 5.
For problems that affect one or more of the removable media drives:
a.
Reseat the following components:
1. Removable-media drive cable (if applicable)
2. Removable-media drive
3. Media tray cable (if applicable)
4. Media tray
b.
Replace the following components one at a time, in the order shown, restarting the blade
server each time:
1. Removable-media drive cable (if applicable)
2. Media tray cable (if applicable)
3. Removable-media drive
4. Media tray
Step 6.
Check for correct advanced management module operation (see the documentation for your
BladeCenter chassis).
Note: Some BladeCenter chassis types have several management-module components that might
have to be tested or replaced (see the Installation Guide for your advanced management module
for more information).
Step 7.
Replace the advanced management module (see the documentation for your BladeCenter chassis).
If these steps do not solve the problem, it is likely a problem with the blade server. See "Removable-media
drive problems" on page 267 or "Universal Serial Bus (USB) port problems" on page 273.
Network connection problems
Use this information to diagnose and solve network connection issues with the blade server.
To check for network connection problems, complete the following steps until the problem is solved:
Step 1.
Make sure that:
• The network cables are securely connected to the I/O module.
• Power configuration of the BladeCenter chassis supports the I/O-module configuration.
• Installation of the I/O-module type is supported by the BladeCenter chassis and blade server
hardware.
• The I/O modules for the network interface that is being used are installed in the correct
BladeCenter I/O-module bays and are configured and operating correctly.
• The settings in the I/O module are correct for the blade server (settings in the I/O module are
specific to each blade server).
Step 2.
Check for correct I/O-module operation; troubleshoot and replace the I/O module as indicated in
the documentation for the I/O module.
Step 3.
Check for correct management-module operation (see the documentation for your BladeCenter
chassis).
