Two switches are cascaded.  Server 1 is on switch 1.  A number of PCs are on switch 2.  Are the PCs sharing the bandwidth of the one uplinked port when connecting to server 1?  Can several ports be used on switch 1 for the uplink to increase the available bandwidth?  How would this be done, specifically on Cisco 2900 switches?

    Yes

    "Can several ports be used on switch 1 for the uplink to increase the available bandwidth?"
    Yes. Using FastEtherchannel.

    "How would this be done, specifically on Cisco 2900 switches?"
    Connect 2 ports on switch 1 to 2 ports on switch 2. Then:

    Switch#config t
    Switch(config)# interface range f0/1 - 2
    Switch(config-int)# channel-group 1 mode desirable (or "on")
    Switch(config-int)# end

    Do this on the interfaces of both switches that are connected to each other.
