Need help with Cisco environment

I recently started working with a  hotel.
they have a corporate network and a "office" network.  since the hotel is a franchise, they have two separate networks. the current provider for the office network is "ATT".  they are getting rid of the ATT line and installing Telepacific. the GM has ZERO documentation. I don't know what belongs to who.  I can only go by what I get when I run ipconfig /all from the computers.  

They have several CISCO boxes - routers/switch/firewalls.  

what would be the recommended approach to this?  I don't have any passwords and limited knowledge about cisco equipment.

would network network assistant help me discover and access the devices?

Sounds like a lot of sleepless nights in your future... :)

Connect to different ports/wifi, note subnets/gateways/domains; try traceroute to the outside, see where you go.
Connect console to Cisco devices, try your luck with no/default passwords, see what you get.
Use nmap or any other network scanner to map the things on subnets.
Trace visible cables between devices.
Draw a lot of diagrams for layers 1, 2 and 3.
Establish a nice hourly rate... :)

You can use cisco password recovery to get access to the config of the equipment WITHOUT DAMAGE!

When we are doing "hostile" takeovers password recovery (or in the cisco case, config recovery) is really helpful!

@Hank: unless password-recovery was disabled (which is a fairly rare case).

Even if it's not a strict 24/7 environment like a hospital, I'd start out with non-intrusive mapping as much as possible. You don't want to get caught pants down in a live environment.

yes it is, but for different equipment you can have different instructions.

google for  "password recovery catalyst 2950" if you have a 2950 switch. or "password recovery cisco 887va", etc.
