SWITCH SETTINGS ON IMPS AND TIPS
--------------------------------
- This note provides a description of the switches on the front panel of
-
- IMPs and TIPs that are important to the correct operation of the
-
- network software. We have had some difficulty in the past when
-
- certain of these switches were set incorrectly, This RFC will be
-
- updated as necessary, to notify site personnel of changes to the
-
- settings.
-
- A. 516 IMPs
-
--------
- The IMP at your site is a model 516 if it has a gray cabinet and two
-
- rows of indicator lights on the front panel. The correct switch
-
- settings are:
-
- 1. Sense switches 1,2,3 and 4: OFF (DOWN)
-
2. PFI/PFH: PFI (UP)
- 3. HALT INH: OFF (DOWN)
-
4. W.D.T.: OFF (DOWN)
- 5. AUTO RSTRT: ON (UP)

- B. 316 IMPs and TIPs
-
-----------------
- The IMP at your site is a model 316 if it is a TIP or if it is in a
-
- black cabinet and has one row of indicator lights on the front panel.
-
- 1. Sense switches 1,2,3,4 OFF (top half depressed)
-
- Site personnel are requested to keep a copy of this RFC near the IMP
-
- and to check the switch settings at their IMP. In addition, the

-
- requested to use this note as a checklist.
