ICP Comms E2T card has no IP address. If you are using the controller’s internal DHCP
server for the E2T: ensure you assigned a static
IP address to the E2T using the correct MAC
address (see “Configure the Layer 2 Switch” in the
“Initial Setup” chapter or the MCD Technician’s
Handbook for instructions).
If you are using an external DHCP server for the
system: verify that options are programmed
correctly (see “Configuring External DHCP
Settings for E2T” in the “Installation Planner”
chapter of the MCD Technician’s Handbook for
instructions).
DHCP is corrupted. Rebuild the DHCP scope.
if DHCP is not running, start by doing a dbms save.
Incorrectly programmed E2T IP
address or incorrect setup of debug
cable.
Verify that E2T VxWorks parameters are correct
(see “Programming E2T via Debug Cable or
Secure Telnet” section of the MCD Technician’s
Handbook for instructions).
RTC is set up with a different virtual
LAN (vlan).
From the RTC shell, remove the VLAN using the cv
command.
You may also have to remove the VLAN on the
E2T. The process is the same, but you do it from
the E2T VxWorks shell.
If the alarm is occurring on a CX/CXi
controller that is running pre- 3300
release 9.0 UR2 software, it is a false
alarm.
To clear the alarm without a reboot:
1. From the RTC shell enter the following
-> lkup “ClearAlarm”
2. This command Identifies the Hex code
associated with the ClearAlarm. Note that this
code is software load dependent. The system
response will be similar to the following:
ClearAlarm (void) 0x0033763c text <======= this
is what I need
LicenseManagerImpl : : ClearAlarm(void) 0x00fc99
ac text
ClearAlarm 0x001136c8 text
value = 0 = 0x0
3. Enter the ClearAlarm(void) hex code. For
example:
--> 0x0033763c( )
E2T card is defective. Check the Hardware Compute Cards form in the
System Administration Tool. If the IP Address for
Slot 2 displays “Not Responding”, replace the E2T
card.
