OAM Interfaces

This section covers the features and description of the OAM (Operation, Administration and Management) interfaces on OAM card supported in TJ1600-6. The OAM interface provides static user interfaces and visual indications for managing operations, administration and maintenance of the system.

Front Panel - HCPOAM03

The HCPOAM03 card provides static user interfaces for configuration and visual indications.

HCPOAM03 card has the following functional features:

Three 10/100BaseT NMS interface (1 NMS can be used as LNMS).
NMS and LNMS interface LEDs (LinkStatus, PktReceive, 10/100 status).
Craft interface (V.24 Async, with M1/F1 control lines – Phy is RS232).
Alarm LEDs for Critical, Major and Minor alarms.
User configurable alarm inputs.
Alarm outputs for Critical, Major and Minor.
Temperature monitoring.

Power specifications

Specification	Range
Input Voltage	-48V DC
Power consumption	15W

Visual indicator details

The visual indicators on the HCPOAM03 card include two LEDs: the ACT (ACTIVE) and the STS (STATUS).

TJ1600-6 HCPOAM03 - Status and Active LEDs indications

Card State	Status LED	Active LED
Card initialization: State before the card initialize is complete on card insertion.	Amber (Steady)	Amber (Steady)
Card in service: Initialization complete and card in service.	Green (Steady)	Green (Steady)
Card mis-match: Node has already configured the slot with some other card.	Amber	Amber
Card failed during boot up.	Red	Amber
Card failed while in-service.	Red	Green
Improper jack-in of the card.	Green (Blinking)	Green (Blinking)
Hard Reset: All devices reset. Goes to initializing state next.	Amber	Amber
Soft Reset: Software is restarted, devices are reinitialized with provisioning. Goes to initializing state next.	Green	Green

There are three alarm visual indications on the faceplate of HCPOAM03 card:

Critical Alarm
Major Alarm
Minor Alarm

TJ1600-6 HCPOAM01 - Alarm LED indication

LED	Color	LED Status
Critical LED	Red	Critical alarm detected by node.
Critical LED	Off	Default State. No Critical alarm detected.
Major LED	Red	Major alarm detected by the node.
Major LED	Off	Default State. No Major alarm detected.
Minor LED	Amber	Minor alarm detected by the node.
Minor LED	Off	Default State. No Minor alarm detected.

Backplane Interface

HCPOAM03 card connects to the backplane and receives the -48V DC input through the backplane.

BITS Interface

BITS interface is provided through an RJ45 connector for the data port and clock port.

NOTE: BITS interface is not supported for this release.

NMS interface

There are three NMS interfaces on the card namely LNMS, NMS1 and NMS2. The NMS Interfaces provide a CSMA/CD based LAN transceiver of an Ethernet link. Each NMS interface is provided on an RJ45 connector. The OAM does not do any processing on this. Out of three NMS ports, LNMS is for LAN connectivity and NMS1 and NMS2 are for Multi Shelf access.

Two LEDs are used to indicate link status of the connector. The NMS interface is associated with two LEDs, Green and Amber.

HCPOAM03 - LED status and their significance for NMS interface

Card State	Green LED Status	Amber LED Status
Link speed 10 Mbps	-	-
Link speed 100 Mbps	-	On
NMS port up	On	-
Receiver Activity	Blink on packet received.	-

Craft interface

The Local Craft terminal is an additional LAN interface. The craft is provided through a RJ-45 connector. The additional LAN interface runs a DHCP server and the port has a fixed IP address 192.168.1.1, which cannot be changed. Hence the LAN port is always available for debugging through the GUI or a telnet session, if there is any problem with the local LAN.

NOTE: Craft interface is not supported for this release.

External alarms interface

The OAM card provides seven external alarm inputs and four external alarm outputs.

Alarm-In: The alarm inputs connect external triggers for events (such as open door or a shelf high temperature) to the OAM card. When an event occurs, which activates the trigger connected to the external alarm input, the node raises an environmental alarm. The external inputs are either enabled or disabled from the node user interface.
The severity, alarm text, and the SNMP trap ID can be edited from the node user interface; for more information refer to the User Interface Guide. The Alm. In (Alarm In) interface is through a RJ-45 connector.
Alarm-Out: The alarm outputs can be used to trigger the operation of external equipment, such as a generator, fan or audible alarm. The alarm outputs are caused by alarms detected by the node. The alarm-outs are classified as minor, major, and critical. The Alm. Out (Alarm Out) interface is through a RJ-45 connector.

NOTE: The 1PPS, ToD and 10M interfaces indicated on faceplate of HCPOAM03 card is not supported.
