GigaVUE TA Series Hardware Installation Guide
Dual BIOS Images
The GigaVUE-TA100-CXP has a dual Basic Input/Output System (BIOS). The BIOS
image is packaged with the software image, starting in software version 4.8.01. The
BIOS contents are stored in flash memory, allowing the BIOS to be upgraded. There
are two flash components, a primary and a secondary.
The following CLI command displays the two flash components and indicates the BIOS
image from which the system booted using asterisks:
(config) show version
...
1st flash version: coreboot-ta100cxp-1.0.0_20170110 Tues Jan 10 08:55:30 UTC 2017 **
2nd flash version: coreboot-ta100cxp-1.0.0_20170110 Tues Jan 10 08:55:30 UTC 2017
...
If there is a component failure in the primary flash, the GigaVUE-TA100-CXP boots
from a backup golden BIOS image in the secondary flash. An SNMP trap can be
configured to be sent when the system has booted from the secondary flash. The trap
may indicate that the primary flash component needs to be serviced. The trap is as
follows:
2ndflashboot: Secondary flash boot notification
If a BIOS upgrade is needed for enhancements in future releases, the BIOS can be
manually upgraded from the CLI using the
coreboot install
command.
Software Upgrade using USB Drive
If a GigaVUE-TA100-CXP does not have network access, there is a USB port on the
front of the chassis.
A software image can be downloaded to a USB drive, the drive can be inserted into the
USB port on the GigaVUE-TA100-CXP, and the software image can be installed from
the drive. Use the format, fat32, for the USB drive.
The following are ways to download a software image to a USB drive:
•
Insert the drive into your computer or laptop and drag and drop the software image
onto the drive.
•
Insert the drive into a GigaVUE-TA100-CXP with network access and use the
image fetch
CLI command with the
usb
parameter.
Air Flow Direction
The air flow direction is from the front of the GigaVUE-TA100-CXP chassis to the rear.
The rear-mounted fans pull air from the front to the back of the chassis. Install the
chassis so the intake air at the front of the chassis is cold.
AC and DC-Powered GigaVUE-TA100-CXP Models
Gigamon provides both AC and DC-powered versions of the GigaVUE-TA100-CXP.
