Cisco STACK-T1-50CM 50 cm Data Stacking Cable for Catalyst 9300

A 50 cm data stacking cable for Catalyst 9300 Series switches. Cisco lists the STACK-T1 cables for both the C9300 and C9300X models, in three lengths: 50 cm, 1 m (STACK-T1-1M) and 3 m (STACK-T1-3M). The cable links the stack ports on the rear of the switches so they run as one logical switch.

Stack speed depends on the switches, not the cable. Standard C9300 models stack with StackWise-480 at 480 Gbps, and C9300X models with StackWise-1T at 1 Tbps. A stack that mixes 9300X and 9300 switches runs at StackWise-480 speed. Cisco supports up to eight members in a 9300 stack.

The 50 cm length is the short option, meant for switches mounted close together in the same rack; choose the 1 m or 3 m cable when the units are further apart.

Check the switch model before ordering. The fixed-uplink C9300L does not use STACK-T1 cables: it stacks with STACK-T3 cables through the C9300L-STACK-KIT, or STACK-T3A with the C9300L-STACK-KIT2. The Catalyst 9200 uses its own STACK-T4 cables. Cisco's higher-scale 9300 models (such as the C9300-48UB) only stack with other higher-scale units, so a cable alone will not join one to a standard 9300 stack.

Separate StackPower cables carry power sharing between switches; this cable carries data only.
