PC-DBA laptop on site
• You can save the existing database
residing on the switch via a
RECEIVE ALL command. When
you need to modify the database,
you can use the switch version as a
basis so you will not have to
reprogram all its custom settings.
• If you lose the switch database
because of battery failure or
because you must perform a Master
Clear, you will NOT have to
completely reprogram the database
(provided you have previously saved
a copy of the custom switch
database onto your laptop).
• You need a laptop with a serial port.
• You do all programming on site.
• PC-DBA is not a direct interface to
the CPU. Therefore, the possibility
exists that a corruption can occur
when transmitting the laptop
database to the switch.
• You must be diligent in performing a
RECEIVE ALL when first arriving on
the customer site, and prior to
modifying their database. If you
neglect to do so, you may
inadvertently perform a SEND ALL
first, thus writing over their custom
programmed database with
whatever database you last used on
the laptop.

• You can program the customer’s
database while off site, and simply
download it to the switch when you
arrive on site. This reduces the
amount of time you have to spend
on site.
