I believe the 7150-24P has ports like 1/2/1-1/2/8, right? You can use these as your trunking ports.
To do this, tag both vlans on the port you want to use, for example 1/2/1. Both vlans can be tagged across one port, then you only need one cable to uplink to another switch.
Or if you want to lag, you can use 1/2/1 and 1/2/2, or more. Then you would need more cables but the vlans would still be tagged across all ports.
