QuickLoop enables servers with host bus adapters that use Fibre Channel
Arbitrated Loop private loops to communicate with Fibre Channel storage
devices through IBM TotalStorage SAN switches. For more information, see
the Brocade QuickLoop User’s Guide.
Secure feature
The Secure feature provides customizable security restrictions through local
and remote management channels on a switch fabric. For more information,
see the Brocade Secure Fabric OS User’s Guide.
Fabric Manager
Fabric Manager provides a GUI that allows the administrator to monitor and
manage a fabric from a standard workstation. For more information, see the
Brocade Fabric Manager User’s Guide.
Extended fabrics
Extended fabrics activation extends SAN fabrics beyond the Fibre Channel
standard 10 km, which enables high performance applications over
extended distances for storage consolidation, data protection, disaster
tolerance, and data sharing.
Remote switch
Remote switch activation extends the distance of the SAN fabric by
enabling two Fibre Channel switches to interconnect over an asychronous
transfer mode (ATM) wide area network (WAN).
Note: To activate these features, go to the following Web site:

Switch initialization
When you start or restart the switch, the following operations are performed:
1. Early power-on self test (POST) diagnostics are run. POST is run before
VxWorks is running.
2. VxWorks is initialized.
3. The hardware is initialized. The system is reset, the internal addresses are
assigned to Loom chips, the Ethernet port is initialized, the serial port is
initialized, and the front panel is initialized.
4. A full POST is run.
5. The links are initialized. Receiver and transmitter negotiation is run to bring the
connected ports online.
6. A fabric exploration is run. This determines whether any ports are connected to
other switches. If so, it determines the principal switch.
7. Addresses are assigned. After the principal switch is identified, port addresses
are assigned. Each 3534 Model F08 tries to keep the same addresses that it
used previously. Previous addresses are stored in the configuration Flash
memory.
8. The routing table is constructed. After the addresses are assigned, the unicast
routing tables are constructed.
9. Normal node port or node loop port (Nx_port) operation is enabled.
