J3 BAUD RST - Speed reset. The factory
default position of the shunt shorts pins 2-3. When the shunt is moved to pins
1-2, the console is reset to 9600 baud on the next power cycle. The following
figures show the location of the console reset jumper, labeled DUART_RST or
BAUD_RST.
Memory
72-pin SIMMs, 60 ns speed. Tin leads. Non-parity and parity SIMMs supported.
Just to be simple, all one type or the other.
Cisco 3640 supports either 32- or 64-bit operation.
Router performance is approximately 20 percent slower in
32-bit mode than in 64-bit mode. To use 64-bit mode, you
must install DRAM SIMMs in pairs of the same size.
Generally, basic software feature sets (such as IP) use
32-bit DRAM SIMMs and robust software feature sets (such
as Enterprise) use 64-bit DRAM SIMMs.
Note:
I dimly remember a snippet that the 3640 will support
parity if both SIMMs in a bank are parity. If not, the
bank will be treated as non-parity {Ed}.
Follow these rules to use 64-bit operation:
- SIMMs in banks 0 and 1 must have:
- Same capacity
- Same access time (in nanoseconds).
- SIMMs in banks 2 and 3 must have:
- Same capacity, and the same size or smaller than those in banks 0 and 1
- Same access time (in nanoseconds)

Ports
Auxiliary port supports 115 Kb/s with flow control, good for high-speed
transmissions (modem).
Console port also transmits at 115 Kb/s, but it has no flow control. Ideal
for console terminals. You obviously can't use the Console as a Console while
uploading the Flash.
System LED
| Color |
Description |
| Off |
Router is not receiving power. |
| Blinking green |
Router is running the ROM monitor. No errors detected. |
| Solid green |
Router is operating normally. No errors detected. |
| Amber |
Router is receiving power but not functioning properly. Possible POST error
or over-temperature condition detected. |
| Alternating amber and green |
Power-on self-test detected. The router is attempting to reload the ROM
monitor. |
RPS LED
| Color |
RPS Status |
| Off |
Not installed. |
| Blinking green |
RPS and power supply are both on. Choose only one by:
- Unplug power supply and use the RPS.
- Turn off RPS and use power supply. RPS can remain connected
|
| Solid green |
Operational. |
Amber
|
Installed but not operational

ACTIVE, READY, and PCMCIA LEDs in Cisco 3640 Routers
| LED |
Description |
| ACTIVE 0, 1, 2, 3, 4, 5, 6 |
Blinks to indicate network activity on the module installed in the
indicated slot. |
| READY 0, 1, 2, 3, 4, 5, 6 |
Functional module installed in indicated slot. If LED is off, slot is empty
or module is not functional. |
| PCMCIA 0, 1 |
Data activity on the indicated PCMCIA slot. |
