Booting the Router

117347-A Rev. A 4-3

Preparing to Boot a Router

You access the boot function in the main Site Manager window by choosing

Administration from the main menu bar.

Booting a router warm-starts every processor module in the router. Pressing the

Reset button on the front panel of the router performs the same procedure.

Booting interrupts router operation, so plan your boot carefully. Before you boot

the router, decide the following:

• Which router you are booting

• Whether to use the default conﬁguration and image ﬁles, or ﬁles you specify

• Whether to use a scheduled boot

FN/LN/CN Router Boot Prerequisite

The PCMCIA/Floppy switch on the Flash System Controller board of an FN

, or CN

router determines where the router looks for the image (ace.out)

and conﬁguration ﬁle when it is booting. The PCMCIA position is for memory

card boot access, and the Floppy position is for diskette boot access.

You can use Site Manager and the Technician Interface to access both the memory

card and diskette ﬁles, regardless of the position of this switch. But you cannot

override the switch setting when booting. For example, you cannot boot from a

diskette if the switch is set to the PCMCIA position.

When you use Site Manager to boot the router, or when you specify an image and

conﬁguration ﬁle in a Technician Interface

boot command, the software veriﬁes

the ﬁles’ existence before allowing the boot to take place.

Note: You can use Site Manager to warm-start a router only. To cold-start a

router to initiate diagnostic tests, you must physically turn off and then turn on

the router, or use the Technician Interface

diags command. Refer to Using

Technician Interface Software for information about the

diags command.
