Planning Considerations

AS/400 as a Router

Limited data is available. A model 400-2132 is able to route about 970kb/s

from one LAN to another and about 75Kb/s from a LAN to twinax.

2.7 Problem and Change Management

At times, the Network Station operating system may stop unexpectedly with a

PA N I C

error. One of two symptoms may appear:

•

PA N I C

appears on your Network Station and a > cursor is shown.

• The display turns reverse video (mostly black) and a > cursor is presented.

To recover from such a condition, you can power off and on the Network

Station or if the

PANIC

error persists can contact IBM support. There are

problem determination tools, available within the Release 3 code of the

Network Station, which an IBM support person can invoke for further problem

determination of the

PANIC

condition.

2.8 Migration Considerations

If you are upgrading from the 5733A07 (R2.5) to the 5648C05 (R3.0) level of

the IBM Network Station Manager licensed program, consider the following

items:

• New Boot Monitor Code:

The boot monitor code in Release 3 contains new functions. We

recommended that you update the boot monitor code on each of your

Network Stations. For instructions on how to update the Boot Monitor

Code, refer to

IBM Network Station Manager Installation and Use

SC41-0664.

• NC Navigator:

The IBM Network Station Manager Release 3 licensed program (5648C05)

does not support the IBM browser. When you install Release 3, the 40-bit

NC Navigator automatically installs. The bookmarks that you used with

your IBM browser will be migrated to the new NC Navigator. If your users

were saving both Navio and IBM Network Station bookmarks, the Navio

bookmarks are migrated and the IBM Network Station browser bookmarks

are saved to a file. The save file can then be imported into the NC

Navigator browser. The 128-bit browser (available in the US and Canada)

can be installed after Release 3 is installed successfully. Refer to Chapter

7, “Replicating a Remote Boot Server Environment” on page 213 a known

problem with NC Navigator bookmarks, after migrating to Release 3.
