Installing a Modular Tape Subsystem (NonStop
Himalaya K-Series Servers)
This subsection describes the steps necessary to install the modular tape subsystem
on a NonStop Himalaya K-series server.
Installing the MFC RS-232/SCSI BIC (NonStop Himalaya K-Series
Servers)
If you plan to attach a tape drive to an MFC, you must replace the standard MFC
RS-232 BIC (with four connectors) with an RS-232/SCSI BIC (with five connectors).
The RS-232/SCSI BIC has an extra connector for an open-reel or cartridge tape drive
(see Figure 1-5 on page 1-11). Part numbers for MFC BICs are listed in Appendix A,
Part Numbers.
Removing an MFC RS-232 BIC
Use the following procedure to remove an MFC RS-232 BIC:
1. Shut down the application software that uses the MFC.
2. Shut down the system software that uses the MFC. Be sure to:
•
Shut down any TACL processes for terminals attached to the MFC
•
Establish new primary paths for the disk drives attached to the MFC
•
Shut down the paths to the internal tape drive and communications lines
For examples, see the support guide for your system.
3. Obtain the appropriate I/O slot number in the system or I/O cabinet from the
completed BIC diagram for the MFC. You can also get this information from the
completed cabinet check list for that cabinet or from the system manager.
4. At the back of the cabinet, remove the cabinet cover and locate the BIC you are to
remove. BICs are in slots 90 through 99 in system cabinets and slots 90E through
99E in I/O cabinets.
5. If cables are connected to the BIC, attach a label to each cable. On the label, write
the name of the BIC connector to which the cable is connected (such as J1 or J4).
Then disconnect the cables.
6. Loosen the thumbscrews that secure the BIC to the card cage. If a thumbscrew
does not move with finger pressure, you can use a slotted screwdriver to remove
the BIC from the cabinet.
