Most newer switched autosense whether a port needs to be crossover or not.

Try it!

True.  If the 16 port switch has an uplink port you could also use a
straight cable from there to port 1 on the 5 port switch.

EASY RULE: Any time you are connecting two network devices there must be at
least one crossover (and an odd number if there are more than one).

A crossover is any time you switch from a T568B pinout to a T568A pinout.

Standard network cable terminations (in most installations) and switch ports
are T568B Most NICs are T568A

So to connect Port 1 (T568B) on a switch to Port 1 (T568B) on another switch
you need a cable that is a crossover T568B on one end and T568A on the
other.

To connect the Uplink Port (T568A) on a switch to Port 1 (T568B) on another
swith you need a straight cable T568B on both ends.

To connect a NIC (T568A) to Port 1 (T568B) on a switch you need a straight
cable T568B on both ends.

To connect a NIC (T568A) to the Uplink Port (T568A) on a switch you need a
crossover cable T568B on one end and T568A on the other

To connect a NIC (T568A) directly to another NIC (T568A) you need a
crossover cable T568B on one end and T568A on the other  (Now that's a small
LAN)
