VT886

The VT886 is a 2U MTCA chassis that provides four full-size and eight mid-size AMC slots that can accept any AMC.1, AMC.2, AMC.3 and/or AMC.4. It also provides CLK1, CLK2, and CLK3 to each slot in addition to the JTAG signals.

The unit’s unique dual tongue feature provides extra power to 4 slots and enables an additional 21 differential pairs between these slots. It also allows up to 8 double-width mid-height AMC modules.

The VT886 has full redundancy. It is capable of having redundant MCH, Power Modules and redundant Cooling Units for high availability. An option exists for redundant/non-redundant clock per MTCA specification. The CLK3 option can be configured for the Fabric clock and Telecom clock.

The chassis has a JTAG Switch Module (JSM) slot per MTCA specification. This provides transparent communication between the front JTAG Port and the selected AMC device. The VT886 has a Telco Alarm as well as Redundant FRU information devices and carrier locator.

Power Supply

The VT886 has a Dual Power Module (PM) option. The PM slots are in the rear with the universal AC input.

Cooling and Temperature Sensors

The VT886 has airflow from right to left with Dual intelligent Cooling Units. This redundancy ensures fail-safe operation should one of the cooling units become non-operational. A sensor detects the presence of the replaceable Air Filter, allowing it to be monitored for when it is due to be cleaned/replaced.

12 chassis mounted temperature sensors monitor the intake and the outtake air temperature throughout the unit.

Telco Alarm

The VT886 is fitted with a Telco alarm that constantly monitors the chassis for any anomalies and alerts the user by LED indication on the Front Panel. It has its own dedicated slot and can be directly accessed via a Micro DB-9 connector.

FRU Information and Carrier Locator

The VT886 has dual redundant FRU information and Carrier Locators. The Carrier Locator is assigned by easily accessible mechanical dip switches. The MCH reads the Locator via its private I2C bus.

No Active Components

Unlike other MTCA chassis on the market, the VT886 has no active components on its back plane, making maintenance and servicing tasks more straightforward.

Scorpion™ Software

VadaTech’s Scorpionware software can be used to access information about the current state of the Shelf or the Carrier, obtain information such as the FRU population, or monitor alarms, power management, current sensor values, and the overall health of the Shelf. The software GUI is very powerful, providing a Virtual Carrier and FRU construct for a simple, effective interface.
