X7-8-Install-IG100 Installation Guide
POST includes the following steps:
1. Preliminary POST diagnostics are run.
2. The operating system is initialized.
3. Hardware is initialized.
4. Diagnostic tests are run on several functions, including circuitry, port functionality, ability to send and receive frames,
all aspects of memory, parity, statistics counters, and serialization.

Boot

Gen 7 platforms implement Secure Boot. This feature enforces validation of the digital signature of the signed Boot Code
image in Boot Flash. It uses a pre-programmed public key HASH inside the CPU-internal-fuses to ensure authenticity and
integrity of the code prior to proceeding with the boot sequence.
In addition to POST, boot includes the following steps after POST is complete:
1. The digital signature of the signed image in Boot Flash flash code is validated against a pre-programmed public key in
the CPU to ensure integrity of the code prior to proceeding with the boot sequence.
2. Universal port configuration is performed.
3. Links are initialized.
4. The fabric is analyzed. If any ports are connected to other switches, the device participates in a fabric configuration.
5. The device obtains a domain ID and assigns port addresses.
6. Unicast routing tables are constructed.
7. Normal port operation is enabled.

Optical Transceiver Requirements

Optics are authenticated as genuine Brocade products during system boot or installation into a port. The user of specific
optics for Gen 7 Brocade switches and blades is required to ensure optimal performance and reliability.
