Remote Management Unit Overview  
Your Dell PowerVault 124T LTO - 3 autoloader includes an Ethernet interface that allows remote administration. The interface, called the Remote Management 
Unit (RMU), includes a Web server that provides a Hypertext Markup Language (HTML) - based graphic user interface (GUI) for ease of use.  
The RMU performs many of the same functions as the front panel interface. These functions include moving tapes,  system operations options, networking 
options, security options, running diagnostic tests, and performing system updates.  
Default Username and Password  
The default username for the Remote Management Unit is  admin . The default password is  password .  
The username and password are case sensitive and should be entered in all lower case letters. The default username and password are valid if no usernames 
have been configured.  
Opening the Remote Management Unit  
The Remote Management Unit has an HTML interface, which means you use a browser to open it. The following Web browsers are supported:  
l For Microsoft ®  Windows ®  —   Microsoft Internet Explorer 5.5 or later    
l For Microsoft Windows Server ®  2003  —   Microsoft Internet Explorer 6.0 or later (with latest security patches)    
l For Redhat ®  2.1  —   Mozilla™ 1.4.2    
l Firefox™ 1.0    
If security is enabled, you need an operator password to access the  Library Operations  page, and you need an administrator password to access the 
Configuration ,  Error Logs and Diagnostics , and  Firmware  pages.

Configuration Page  
The  Configuration  page includes a submenu on the left - hand side of the page. You can set the  System Operations ,  Networking , and  Security  options from 
this page.  
System Operations Options  
The options listed under  System Operations  include  SCSI ID ,  Compression ,  Barcode Reader ,  Cleaning Tape ,  Magazines , and  System Time .      
						

							SCSI ID  
You can change the drives SCSI ID from the Remote Management Unit. To change the SCSI ID:  
1. From any page, click the  Configuration  heading. The  Configuration  screen displays.  
2. Under  System Operations , select  SCSI ID .  
3. Click the drop - down box to select a number to assign for the new SCSI ID.  
4. Click  submit .  
Compression  
For the Dell PowerVault 124T LTO - 3 autoloader, data compression is drive - dependent. The front panel and the Remote Management Unit will display whether 
or not compression is enabled.  
Compressing the data means that the drive can write more data to the same amount of tape. Compression also increases the performance of the data 
transfers from or to the SCSI bus.  
To view the compression setting:  
From any page, click the  Configuration  heading. The  Configuration  screen displays. Under the  Compression  heading, the current compression setting is 
displayed as  Compression Enabled  or  Compression Disabled .  
Bar Code Reader  
The bar code reader can be enabled or disabled. Disabling the bar code reader  prevents the reader from attempting to read label information. If non - bar code  
labels or no labels are being used, disabling the bar code reader will reduce  initialization time at startup or system reset.   
Either a power cycle (through the front panel button) or an autoloader reset (through the  Autoloader Reset command found on the Error Logs and Diagnostics 
page) is required  for the setting change to take effect.   
SCSI  Barcode Length sets the maximum number of barcode characters that will be  returned in the SCSI Read Element Data. The display of barcode information 
on  the Web interface and Operator Control Panel (OCP) are unaffected by this  setting.  
Setting the  SCSI Barcode Length to 0 disables truncation of the barcode and the full  barcode will be returned in the SCSI Read Element Data.   
This  setting is particularly useful if you have a pool of media previously  catalogued by another device that has a limitation on the number of barcode  characters 
that can be read (typically 6 or 9).  Adjusting the PV124T setting to match the previous hardware prevents the  user from having to re - catalog all barcode 
labeled media previously used in the  other device.  
The autoloader does not need to be reset when changing the Barcode Length.  
To change  the Barcode Reader settings:  
1. From any page, click the  Configuration  heading. The  Configuration  Screen displays.    
2. Under the  Barcode Reader  section, select the desired  Enable/Disable  option and  Barcode Length  setting and click  Submit .    
3. If the  Enable/Disable  option is changed, the message  This will require a  power cycle and host backup software configuration change  will be displayed.  
4. Select  OK . The front panel and  Web interface will display  Please Power Cycle .     
5. Either a power cycle (through the  front panel button) or an autoloader reset (through the Autoloader Reset  command found on the Error Logs and 
Diagnostics page of the Web interface)  is required for the change to take effect.

Setting the Magazines  
This setting is used to report the number of storage elements and the element address to the SCSI host. This setting must match the physical configuration in 
order for correct information to be reported. This setting only affects the information reported to the SCSI host. This setting does not affect the access to 
magazine slots from the front panel or the Remote Management Unit. Those interfaces are based on the physical configuration.  
When configured for  Both  magazines, the autoloader always reports 16 storage elements to the SCSI host. This allows the removal and reinstallation of 
magazines without affecting what is reported to the host. When configured for  Left  or  Right , the autoloader will always report 8 storage elements to the SCSI 
host.  
The element addresses vary depending on which magazine is configured. If  Left  or  Right  is selected, and both magazines are physically installed, the front 
panel and the Remote Management Unit allow the user access to the other magazine, but the SCSI host will not have access.
