How to cascade Cisco 2960s

The only way to do that is to configure them as a cluster and to tell you the truth it's ugly . Myself I would just star them all off a single switch and give each their own ip address for management . If need be make the connections trunks if you need that function . If you want to cluster them then look at this doc.

You will be managing 4 separate switches.
The uplinks between the switches can be made etherchannels to get up to 4Gb/s between switches.
You don't need crossover cables - these switches should have auto-MDIX on their inetrfaces.

DvcAkv, your network configuration is usually dictated by your structured cabling.
Ideally, you nominate one switch to be your "core" and then each of the other 3 switches uplinks to your "core". The core then carries the uplink to the WAN (or wherever).
The uplinks should be something like this:
"Core" 2960:
Ports 1 & 2 = portchannel 2
Ports 3 & 4 = portchannel 3
Ports 5 & 6 = portchannel 4
2960 #2:
Ports 1 & 2 = portchannel 2
2960 #3:
Ports 1 & 2 = portchannel 3
2960 #4:
Ports 1 & 2 = portchannel 4
Each switch should have :
"Interface VLAN 1
ip address nn.nn.nn.n 255.255.255.0"
default gateway nn.nn.nn.nnn
Ports that are *not* in an etherchannel should have
"spanning-tree portfast"
With only 4 switches, there's probably no need to have seperate VLANs and multiple subnets.
