** NOTE **

 You must press the Return key after you type each command in procedures
described in this release memo.



Installation

Because your Series/200 server is booted from an NCS/150, install
SW/200-A/BSC/SDLC-NCS/150 on the NCS/150.  To copy the software from the
distribution diskette to the SW/150-NCS diskette, follow these steps:

1. Attach a terminal to port 0 of the NCS/150.

2. Insert the SW/150-NCS-UTIL diskette in the NCS/150 disk drive, then press
the  Reset switch.

3.  After the NCS/150 is finished booting, enter the following sequence on the
keyboard:

 <RETURN>.<RETURN>

 That is, press the Return key, the period (.) key, and the Return key in
succession.

4. Remove the SW/150-NCS-UTIL diskette, then insert the SW/150-NCS diskette in
the disk drive.  Type the following command:

 ls -lx /BIN

 This command displays the contents of the software image currently
available on  the SW/150-NCS diskette.

5. Because the SW/150-NCS diskette can contain the software for two product
types  only, for example, CS/200 and CS/1, it may be necessary to remove
software from  the diskette to make room for the file containing
SW/200-A/BSC/SDLC-NCS/150  Version 22020.  Type "rm <filename>" if you need to
remove a file.

6.  If the file cs200x already exists, remove it by typing the following:

 rm /BIN/cs200x

7. Perform a file system check by typing the following command:

 fsck -c

8.   Create a  file named cs200x on the SW/150-NCS diskette by typing the
following  command:

 cr /BIN/cs200x 200 rwx 103000

9. To copy the software image from the SW/200-BSC/SDLC-NCS/150 Version  22020
distribution diskette to the newly-made cs200x file on the SW/150-NCS
diskette, type the following command:

 cf #0 /BIN/cs200x

10. When the system prompts for the source diskette, remove the SW/150-NCS
diskette.  Insert the SW/200-A/BSC/SDLC-NCS/150 Version 22020 diskette.
Then press the Return key.

11. When the system prompts for the destination diskette, replace the SW/200-
A/BSC/SDLC-NCS/150 Version 22020 diskette with the SW/150-NCS diskette.
Then press the Return key.  The copying process is finished when the following
message is displayed:

 Copy completed

After you install the software, you will have to redefine the global
parameters, clearing house names, macros, and port configurations.

If you use the configurations, macros, and global files copied from the
SW/200-A/BSC/SDLC-NCS/150 Version 22000 or earlier diskette, you must use the
SETD com mand to set the value of the AUditTrailType, TimeZone,
DaylightSavingsTime, and NetMapBroadcast parameters after booting the
Series/200 server.


** NOTE **

 If your Series/200 server is not already bound to the NCS/150, you should
use the  BInd command to enable your Series/200 server to boot from the
NCS/150.  Refer  to Section 5.3 of the NCS/150 Installation and Operation
Guide for information on  using the BInd command.


Limitations

SW/200-A/BSC/SDLC-NCS/150 Version 22020 has the following limitations:

* Only three echo requests may be outstanding at any given time.  If more
than three  users simultaneously enter the PIng command, the following message
appears:

 Can't Ping now - try later

* Because your Series/200 server is booted from an NCS/150, you cannot set
the  MacType parameter to IEEE.
