G-TAP A Series 1

This section introduces the G-TAP A Series 1 devices, describes their features and functions, and provides an orientation to the physical layout of the G-TAP A-TX and G-TAP A-SF models. It includes the following major sections:

This topic covers only G-TAP A Series 1 software version 2.3.01 and above.

Note:  Hardware revision A1 requires minimum software version 2.3.01. If you are using an earlier version of the G-TAP Series refer to the documentation for that version. For example, G-TAP A Series 1 User’s Guide Version 2.2.26.

Version 2.3.01 includes the following new features for the G-TAP A-TX and G-TAP A-SF:

Feature

Description

Battery Detection

Battery presence or absence is indicated.

Battery Temperature Monitoring

Battery temperature within specification is indicated.

Battery Exercise Test

Battery health is maintained by a Battery Exercise Check (BET) once per 90 days.

Battery Health Check

Battery heath checks are done regularly. A new dedicated battery LED indicates the battery's state of health.

Power Over Ethernet (PoE) Pass Through

G-TAP A-TX network ports allow for PoE pass through.

BET Logging

Last four records of the BET are saved in non-volatile memory. The new show batterex command displays the records.

BET Scheduling

New CLI commands set the schedule for the BET.

Non-constant Charging

Battery charging stops when the battery is at 100% capacity. Charging starts at 95% capacity.

SNMP Traps

New traps have been added for reporting changes related to battery presence or absence and battery and board temperature out of limits.

The G-TAP A Series 1 implements Gigamon’s unique Always-On architecture, eliminating network link downtime through the use of up to four power sources, including primary AC, DC, or Power over Ethernet (PoE) sources, and a secondary on-board battery backup. Primary power sources charge the backup battery until it is at 100 percent capacity and starts charging at 95 percent capacity, so it is ready to assume the power load in the event of a power failure on the primary sources.

The G-TAP A Series 1 offers the following features and benefits:

Benefit

Description

Always-On Power Sources

Primary Power through AC, DC, or PoE (Power over Ethernet).

Backup Battery Power is maintained for up to one hour, eliminating link renegotiation delay due to power loss.

SNMP Visibility

SNMP Traps report changes in link state, power sources, battery levels, battery state of health.

Power Supply Tray Integration

Integrates with 1U AC or DC Power Supply Trays capable of powering up to 8 fully-loaded, 3-across Rack Mount Trays (up to 24 separate taps).

Passive Monitoring and Fault Tolerance

Provides completely passive full-duplex monitoring and absolute fault-tolerance.

GigaVUE Integration

Easy integration with the full family of GigaVUE data access switches for maximum flexibility.

Supports Standard Network Speeds/Implementations

G-TAP A-TX provides connectivity for 10/100/1000 Base-T (UTP) copper Ethernet links.

G-TAP A-SF supports SFP (SX/LX/ZX/Cu) and SFP+ (SR/LR/ER/LRM) transceivers, as well as Direct Attach Cables (SFP+ Copper) for connectivity to 10G/1G fiber and copper Ethernet links. Tap speed is determined by the external devices connected to the Network ports – both must be running at the same speed.

See G-TAP A-SF Transceiver Notes and Rules on page 39 for more information on the types and combinations of transceivers supported for use with the G-TAP A-SF.

G-TAP A Series 1 taps are available with AC or DC power and integrate with optional rack mount trays and power supply trays, as follows:

The G-TAP A Series 1 features a consistent set of ports and LEDs across all individual models. The major differences between models are in the Network and Monitor/Tool port types – as shown in the following figures – the G-TAP A-TX uses RJ-45 copper ports while the G-TAP A-SF supports a full range of SFP, SFP+, and Direct Attach Cable transceivers.
