Alarm port functionality on the IR809

Previous versions of software for the IR809 did not support the alarm port. With 15.6(1)T, the alarm port is now functional. When an alarm is triggered or cleared, an error message is seen on the console, as well as SNMP message generated. The alarm LED is activated or deactivated with a trigger or a clear. Note that on 15.6(1)T, show platform led doesn't provide the ALM led status

Alarm Input Port wiring is documented in the IR809 Hardware Installation Guide, Connecting the Router section.

Change in reset button behavior on the IR809 and IR829

The IR809 and IR829 have changed the way the reset button works. With 15.6(1)T, the IR800 series performs in the same manner as the C819. The high level description of the functionality works like this:

• The IR800 will perform both image and configuration recovery
• Press and hold the reset button while powering up the router
• During warm reboot this button has no impact on performance
• Simply pressing the button at any time does not reset the router
• The router will not react to the reset button if it is pressed after power-up because the button needs to be pushed before turning ON/inserting power – to make sure that the condition is detected.
• The push-button cannot be used to boot a IOS image from network. The golden image has to be on flash: only

---

Note For the location of the reset button see the appropriate IR809 or IR829 Hardware Installation Guide.

Perform the following steps to use this feature:

---

Step 1 Unplug power.

Step 2 Press the reset button on the router.

Step 3 Power up the system while holding down the reset button.

The system LED blinks four times indicating that the router has accepted the button push.

 

---

Note To simplify the boot process, the IR800 routers do not support the ROMMON configuration register and the associated CLI commands. The IR800 either boots the pre-configured images, or stops at the ROMMON prompt for user intervention.

Guest OS enhancements on the IR829

Guest OS enhancements include:

• Cisco distribution is based on Yocto Project 1.8 Reference Distro, with basic services enabled:

– IPv4/IPv6

– DHCP

– NTP

– AAA (Radius)

– Python 2.7

– Basic debugging tools (tcpdump, top, etc)

– bash

• Serial relay for Guest OS control of the Serial Interface

– Async 0 and Async 1 respectively reserve line 1/5 and 1/6 to relay serial data to the corresponding Guest OS /dev/ttyS1 and /dev/ttyS2

Serial Relay Configuration

GOS is installed through the IOX bundle install process and can be started/stopped and upgraded from IOS CLI

Verification for digitally-signed GOS image distributed via Cisco DevNet must be installed using the guest-os image install command only. Details on this command and additional information can be found in the Guest Operating System chapters of the respective Hardware Installation Guides for the routers found under:

http://www.cisco.com/c/en/us/support/routers/800-series-industrial-routers/tsd-products-support-series-home.html

Serial Line Internet Protocol (SLIP) encapsulation support

SLIP defines a method of sending IP packets over standard asynchronous serial lines with minimum line speeds of 1200 baud. Serial ports may be assigned to the Guest OS, directly passing traffic to /dev/ttySx

• Show controller async 0 (or 1) to display associated line
• Supported IOS SCADA protocol translation

– IEC 60870-5-101 to IEC 60870-5-104

– DNP3 to DNP3/IP

More information can be found in the Configuring SLIP and PPP Configuration Guide:

Cisco IOS Release 15.6(1)T

The following sections list caveats for Cisco IOS Release 15.6(1)T:

Open Caveats

• CSCuu86884

After the IR800 reloads, vlans are not added to vlan database.

Workaround :

Add vlans manually after reload

• CSCuu49331

LED status report is inconsistent across different commands.

Workaround :

None

• CSCut75469

IR829 is not getting GPS data after router bootup

Conditions : After router bootup, sometimes the modem is up but does not get GPS data.

Workaround: Power cycle the modem.

• CSCuu49331

LED status report is inconsistent across different commands

Conditions : PoE LED will go back and forth between yellow and green when there is a PoE device in deny power state. Typing show platform led or show platform led summary will sometimes show yellow, sometimes shows green.

Workaround : Remove the device that has been denied for power allocation

• CSCuu60617

Media-type rs485 is configurable under IR800 serial port 0 interface (async1), however the serial port 1 (async1) interface does not support media-type rs485.

Conditions : When you configure 'media-type rs485" under the async1 interface, the configuration is acceptable.

Workaround : None

Closed Caveats

• CSCuv48606

Permanent license was lost after reload

• CSCuu45211

Conditions : Originally GobiSerial was connected to ttyUSB1, ttyUSB2, and ttyUSB3 in this scenario. After re-inserting the SIM, GobiSerial is now connected to ttyUSB0, ttyUSB1, and ttyUSB2 with USB interface is still connected.

• CSCuv53403

IR829GW-LTE-GA-ZK9 P2B OS show env cmd crashed system at 70C

• CSCuv67596

IR 829 crash during http copy of 0 byte file

• CSCuu86919

Bundle image installation fails on unit with USB key is inserted

Conditions:

When IR829 unit is loaded with IOS image 15.5(2.25)M0.1, hypervisor 0.28, FPGA version 1.0.0 and BIOS version8 and boots up with USB inserted, bundle installation fails.

Workaround:

Remove USB key from an IR800 unit, reload unit and boot unit up. Unit is able to execute bundle installation to upgrade new image release.

• CSCuu42865

The show environment temperature command has high temperature threshold

Example:

IR800# show environment temperature

Temperature:

-----------------------------------------------------------

Sensor MajorThresh MinorThres CurTemp Status

(Celsius) (Celsius) (Celsius)

-----------------------------------------------------------

Sensor 1 75, -25 60, -15 47 OK

-----------------------------------------------------------

The IR8x9 data sheet and product specifications refer to ambient temperature while the temperature sensor on the IR8x9 is measuring internal temperature.
