The 10 port module is just a pass through allowing direct connection to each blade nic, you should have 2 of these giving connections to the 2 nics on each blade. These are gigabit only, so if your switches are 10/100mb then you won't get a connection.
Dear expert, I just received an old Dell Chassis 1855. everything seem ok but now i have trouble at switch module: When i connect a port on switch module with laptop, the port on switch module up and work fine. I can ping from laptop to blade and blade to laptop. But when i connect a port on switch module with switch Cisco or any normal switchs the port on switch module down, no led blink :(. I try config cisco port as mode access, mode trunk but it wasn't work. i try with other ports on switch module but it's the same. my switch model is dell BMX-PHY 10 port i try to connect to switch module throuht DRAC but:  DRAC/MC:connect switch-1THIS ACTION IS NOT ALLOWED - THIS MODULE DOES NOT SUPPORT SERIAL CONSOLE. thanks alot!!
Switch module on dell chassis 1855 cannot connect with Switch Cisco
