Suggested action

 

 

 

 

Remote control does not work

 

The remote console requires a display setting of 1024x768@60Hz in the blade server

with default SuSE Linux

 

operating system. The default resolution in SuSE is 1024x768, but the default refresh

version 8.0 display settings.

 

rate falls somewhere between 50Hz and 60Hz. The remote console does not work for

 

 

a blade server running SuSE with a display refresh rate other than exactly 60Hz. The

 

 

message “eServer/No video available” displays.

 

 

Other operating systems do not exhibit the problem.

 

 

Set the refresh rate in the XF86Config file to exactly 60Hz.

 

 

There are two methods.

 

 

v Method 1 (unattended network install, prevent the problem): Modify the

 

 

AutoYaST control file to specify 1024x768@60Hz.

 

 

1. Run the graphical interface to the AutoYaST control file to set the VESA video

 

 

mode to 1040x768@60Hz. The graphical interface creates the AutoYaST

 

 

control file.

 

 

 

2. Edit the resulting AutoYaST control file to set the value for min_vsync to 60.

 

 

During an unattended network install, the YaST program uses the AutoYaST

 

 

control file to modify the XF86Config file (/etc/X11/XF86Config); these changes will

 

 

cause XF86Config to set the display resolution to 1040x768 with a refresh rate of

 

 

60Hz.

 

 

 

-- OR --

 

 

 

v Method 2 (situation has already occurred): Modify the xF86Config file.

 

 

1. In the Monitor section of /etc/X11/XF86Config, change the value of

 

 

VertRefresh to 60, as shown in these sample lines.

CD-ROM drive problems

 

 

 

 

 

CD-ROM drive is seen as

 

If the SuSE Linux operating system is installed remotely onto a blade server that is

/dev/sr0 by SuSE.

 

not the current owner of the media tray (CD-ROM drive and USB ports), SuSE sees

 

 

the CD-ROM drive as /dev/sr0 instead of /dev/cdrom, establish a link between

 

 

/dev/sr0 and /dev/cdrom as follows:

 

 

1. Enter the following command:

 

 

rm /dev/cdrom; ln -s /dev/sr0 /dev/cdrom

 

 

2. Insert the following line in the /etc/fstab file:

 

 

/dev/cdrom /media/cdrom auto ro,noauto,user,exec 0 0

Type 8730, Type 8720 specifications

The IBM Type 8720 and Type 8730, part of IBM's extensive line of printers, stand out as reliable and technologically advanced devices designed for both small and large-scale industries. These printers, which were introduced in the early 1990s, catered to the evolving needs of businesses by delivering high-quality output combined with versatility and efficiency.

One of the main features of the IBM Type 8720 is its innovative line printer technology. Unlike traditional printers that utilized a single print head, the 8720 employs a unique printing mechanism that utilizes multiple print wires, ensuring faster print speeds and more precise character formations. This multi-wire technology enables the printer to achieve a print speed of up to 1,500 lines per minute, making it ideal for high-volume printing environments.

The IBM Type 8730, on the other hand, builds upon the foundation set by the 8720 by introducing more advanced features aimed at enhancing user experience. Among its key characteristics is its advanced processing capability, which allows for more complex document handling and high-quality graphics outputs. The 8730's capability to support a range of media types, including labels, envelopes, and fanfold paper, further enhances its versatility, enabling businesses to print various documents without needing multiple machines.

Both printers are designed with user-friendly interfaces that simplify operations and maintenance. Their modular design allows for easy upgrades, ensuring that companies can keep pace with changing printing demands and technological advancements. Additionally, their robust build quality guarantees long-lasting performance even in demanding environments.

In terms of connectivity, the IBM Type 8720 and 8730 support a variety of communication protocols, including parallel and serial interfaces, which facilitate easy integration into existing network environments. This connectivity ensures that businesses can seamlessly connect the printers to their mainframes or personal computers, streamlining the printing process.

Overall, the IBM Type 8720 and Type 8730 are exemplary allies for businesses seeking efficient, high-speed printing solutions. With their advanced technologies, extensive features, and reliable performance, these printers have maintained a loyal following and continue to be relevant in the realms of business printing, showcasing IBM's commitment to innovation and quality in the field of printing technology.
