10. Memory Backup Battery:
The SRAM is backed up by a rechargeable battery when input power is removed. This battery should
retain the data for a minimum of 3 days. If data in the SRAM is determined to be corrupt after power up,
all data, including flash memory, is considered invalid and is erased. All configuration data must be re-
downloaded.
Note:
The initial charge of the battery may take up to 48 hours to be fully charged.
11. Status LEDs:
Power-up:
All LED's
OFF
.
Initialization
: After power is applied, LED
1 is ON for about 15 seconds, then LED’s 2 through 7 are flashed
once at the beginning of initialization. LEDs 5, 6 and 7 are turned ON for approximately 1 second after the
hardware initialization has completed, then the application code is initialized. The amount of time the
application takes to initialize depends on the size of the database, about 1 second without a card database.
Each 10,000 cards will add about 2 seconds to the application initialization. When LED's 1 through 4 flash
at the same time, data is being read from or written to flash memory, do not cycle power when in this state.
If the sequence stops or repeats, perform the bulk erase procedure, see section 4. I
f clearing the memory
does not correct the initialization problem, contact technical support.
Running:
After initialization is complete, the LEDs have the following meanings:
LED
DESCRIPTION
1
Off-Line / On-Line: Off-Line = 20 % ON, On-Line = 80 % ON
2
Host Communication Activity
3
Readers (combined):
Clock/Data or D1/D0 Mode = Flashes when Data is Received, Either Input.
RS-485 Mode = Flashes when Transmitting Data
F/2F Mode = Flashes when Data/Acknowledgment is Received
4
Input IN1 Status: OFF = Inactive, ON = Active, Flash = Fault See Note 1
5
Input IN2 Status: OFF = Inactive, ON = Active, Flash = Fault See Note 1
6
Cabinet Tamper
7
Reserved for Future Use
D9
Relay K1: ON = Energized
D10
Relay K2: ON = Energized
YEL
Ethernet Speed: OFF = 10 Mb/S, ON = 100 Mb/S
GRN OFF = No Link, ON = Good Link, Flashing = Ethernet Activity
Note 1: If this input is defined, every three seconds the LED is pulsed to its opposite state for
0.1 seconds, otherwise, the LED is off.
12. IT Security
When installing the LP1501, it is important to ensure that it is done in a secure manner.
Upon installation, the user accounts to the web configuration page should be created with secure
passwords, and that all DIP switches are in the off position for the normal operating mode. The LP1501 is
shipped from the factory with a default login account, which is enabled when DIP 1 is moved from OFF to
ON. The default login user name and password will be available for five minutes once enabled. Therefore,
it is important that at least one user account is defined, and the DIP switches are set to OFF before the
LP1501 is commissioned. It is also highly recommended not to configure the LP1501 with an IP address
that is accessible from the public Internet.
To further enhance network security, options are available to disable SNMP, Zeroconf discovery, as well
as the web configuration module itself. Additionally, data encryption can also be enabled over the host
communication port.
