PCMCIA Slots
The Management IV module has two PCMCIA slots, numbered 1 and 2.
• In a 4-slot chassis, slot 1 is on top and slot 2 is on the bottom.
• In an 8-slot chassis, slot 1 is on the right and slot 2 is on the left.
• In a 15-slot chassis, slot 1 is on the right and slot 2 is on the left.
Some flash file management operations require that you specify the flash card slot(s) or subdirectory path(s)
involved in the operation. For example, when you copy a file to or from a flash card, you must specify the flash
card you are copying to or from and the subdirectory path for the file location. However, some other commands
do not require a flash card slot or subdirectory path as a parameter. Instead, these commands assume that you
want to perform the operation on the flash card slot and path that currently has the management focus.
The management focus determines the default flash card and subdirectory path (if applicable) for a file
management operation. For example, when you list a directory of the files on a flash card, the PCMCIA slot and
subdirectory path parameters are optional. If you do not specify the slot or subdirectory path, the software
displays the contents of the subdirectory that currently has the management focus on the card in the slot that
currently has the management focus. As another example, the command for deleting a file from a flash card does
not require that you specify the PCMCIA slot or subdirectory path. If you do not specify the slot or subdirectory,
the command deletes the file from the flash card and subdirectory that have the management focus.
When you power on or reload a device, if the management module contains only one flash card, the slot that
contains the flash card receives the management focus by default. If both slots contain flash cards, slot 1 receives
the management focus by default.
To determine the slot and subdirectory that currently have the management focus, enter the pwd command. (See
"Determining the Flash Card Slot and Subdirectory Path That Currently Have the Management Focus" on page 5-
20.) To change management focus to the other slot or subdirectory, enter the cd... or chdir... command. (See
"Switching the Management Focus" on page 5-21.)
Commands that accept a slot number as a parameter can accept either of the following values:
• slot1 – indicates slot 1
• slot2 – indicates slot 2
The CLI provides commands to switch the focus from one PCMCIA slot to the other and to determine the slot that
currently has the focus.
Subdirectories
The software supports subdirectories on the flash card.
Software release 07.1.00 enhances the PCMCIA flash card support by enabling you to create and navigate
among DOS-like subdirectories on a flash card.
You can create up to 512 subdirectories from the root directory level. The actual number depends on how you
name the subdirectories. If you use names that are not more than eight characters long for each directory, then
you can create 512. If you use longer names, the name information occupies more space in the file system and
you therefore can create fewer than 512 subdirectories.
The limit of 512 or fewer subdirectories applies only to ones you create at the root directory level. The number of
subdirectories you can create at another subdirectory level is limited only on the amount of space on the flash
card.
The full path name for a file's location can be a maximum of 260 characters. You can nest subdirectories as deep
as you want so long as the full path name is 260 characters or less.
When you include a subdirectory path in a file management command, use a backslash between each level. For
example, to create a subdirectory for flash code and copy a flash image file to the subdirectory, enter the following
commands:
BigIron# mkdir slot1 \RouterCode\07100
BigIron# ncopy tftp 10.10.10.1 B2R07100.bin slot1 \RouterCode\07100\
