User’s Guide
Thus, subnet addresses for routers range from 101 to 104 and correspond to the router levels.
The numbers on the rotary switch are in hexadecimal: 0–F.
 If the switch is at setting 0, the router will reset to its factory state, losing crosspoint values.
You should avoid leaving the switch at setting 0.
Testing
If your system fails in any way, please refer to Trouble-Shooting , on page 33.
Stand-Alone Router
A stand-alone CR6400 router is a single router that is not connected to a network and (presum-
ably) has a captive panel mounted on the front.
The router’s rotary switch must be set to a value in the range [1–4].
 The panel will power up in the locked state. The ‘Panel Lock’ button will be red. Just press the
red button to clear the lock.
1 Ensure that the router has power. Either or both of the power indicator LEDs should be on.
If that is not the case, then check the power indicator LED of the router’s power supply and
check the connectors of the power supply’s cables. Replace the power supply if it is defec-
tive.
You might want to use the power supply strap to help the line cable secure. See Power Cord
Retention for the PS0012 Power Supply on page 47.
2 Examine the captive panel. Are all the selection buttons illuminated? (Most will be low-tally.)
Some of the function buttons (at the right) will be illuminated and some will not.
3 Perform one or more takes using the panel.
(Press the destination mode button followed by a selection button. Then press the source
mode button followed by a selection button.)
You do not need to connect any devices to a router to see whether it switches, but it helps in
testing if you do. Button status on the control panel reflects the router’s state. However, con-
nected devices will give you visual and auditory feedback regarding the quality of the
switched signals.
4 Perform a panel lock. Press the panel lock button and it should turn red. (When the panel is
locked, other buttons are disabled.)
5 Perform a destination lock. Select a destination then press the ‘Destination Lock’ button.
Both buttons should turn red. Press the ‘Destination Lock’ button again. Both buttons
should revert to amber.
6 Exactly one of the level selection buttons should be bright. The other level buttons should
be off. (There are 4 level buttons; the high-tally button corresponds to the level you config-
ured with the rotary switch.)
 If no level selection button is lit, you might have set the router’s rotary switch to a posi-
tion other than 1–4.
If the router and panel pass all of these simple tests, it is likely to be working properly. You can
now proceed with I/O connections and more exhaustive and detailed testing that is dependent
only your installation.
