Auxiliary flash slots
Auxiliary flash slots support flash PC cards where you can store boot images, startup and running
configuration files, and other system files, in addition to what is stored in system flash memory.
This allows you to perform system management tasks, such as copying files between flash PC
cards, or copying files between a flash PC card and flash memory.
For maximum performance, it is recommended that you use Brocade auxiliary flash cards, part
number FLASH-PCC, which can be ordered from Brocade. Brocade auxiliary flash cards ship with
the label on the bottom of the card; take caution to insert the card with the label on the bottom
side.
Some older auxiliary flash cards can be inserted the wrong way in the slot because there is no
indication in the card about which is the right way. If you insert the card backwards, you will see
continuous messages in the console and the card inserted/ card removed syslog. If this occurs, you
must remove the card and reinsert it the correct way.
External compact flash
MR2 management modules do not contain an auxiliary flash slot. Instead, they contain a 2 GB
internal compact flash card and an external compact flash drive. MR2 management modules come
with a factory installed compact flash card in the external compact flash slot. The internal compact
flash provides greater storage space for image retention, improving the upgrade process.
Do not use compact flash cards over 2GB; they will render the system unstable.
The internal compact flash card cannot be accessed for removal or replacement.
The external compact flash slot allows you to insert a 2 GB compact flash card. If you need to
replace or add an additional compact flash card, contact Brocade technical support.
Console port
The console port is a standard DB-9 serial connector through which you can attach a PC or terminal
to configure the router using the CLI.
The console port interfaces the control plane only. It does not interface the data plane.
10/100/1000 Ethernet port
Management modules also contain a 10BaseT, 100BaseTX, or 1000BaseTX auto-sensing,
auto-negotiating Ethernet port. This port has an RJ45 unshielded twisted pair (UTP) connector.
Typical uses of this port include, but are not limited to, the following:
• Connecting a PC to configure, monitor, and manage the system through a Telnet or SSHv2
connection.
