STACK-T3A-50CM Description

The STACK-T3A-50CM is a Cisco Catalyst 9300L and 9300LM Series Type 3A StackWise-320 stacking cable for data stack links between adjacent fixed-uplink switches. The cable is 0.5 m long, has a 1.6 in. minimum bend radius and joins stacks of up to eight switches through the C9300L-STACK-A adapter. The cable pairs only with Type 3A adapters on Catalyst 9300L and 9300LM, and support starts with Cisco IOS XE Cupertino release 17.9.

Application Scenarios

Adjacent Switches In One Rack

In a wiring closet with two Catalyst 9300L or 9300LM switches mounted one above the other, the cable links their C9300L-STACK-A adapters between the stack ports without leaving extra slack behind the rack.

Mixed 9300L And 9300LM Stack

A stack that combines Catalyst 9300L and 9300LM members uses the cable as the Type 3A link, because Catalyst 9300LM switches stack only over Type 3A cabling at StackWise-320.

Not applicable for 0.5 m cable

STACK-T3A-50CM is the default 0.5 m cable in C9300L-STACK-KIT2 and covers both Catalyst 9300L and Catalyst 9300LM, while STACK-T3-50CM is the default cable in C9300L-STACK-KIT and is listed for Catalyst 9300L only. Racks where members are not adjacent move to STACK-T3A-1M at 1 m or STACK-T3A-3M at 3 m, and STACK-T3A-3M needs a 3.2 in. / 82 mm bend radius against 1.6 in. / 41 mm on this cable. A stack with any Catalyst 9300LM member must stay on the Type 3A family, so STACK-T3-50CM is not an alternative there.

Ordering Checklist

  • Catalyst 9300L hosts: Order for Catalyst 9300L fixed-uplink switches, such as C9300L-24T-4X-E and C9300L-48P-4X-A. Catalyst 9300L models stack only through the C9300L-STACK-KIT or C9300L-STACK-KIT2 path; Catalyst 9300 modular-uplink switches use STACK-T1 cables instead.
  • Catalyst 9300LM hosts: Order for Catalyst 9300LM fixed-uplink switches, such as C9300LM-24U-4Y-E, which stack through C9300L-STACK-KIT2. A Catalyst 9300LM order needs Type 3A cabling from C9300L-STACK-KIT2 rather than Type 3 cabling.

Questions & Answers

  • Can STACK-T3A-50CM be used to stack C9350 Series Smart Switches?

    No. Per the C9350 stacking cable documentation, T1A and T3A cables do not interoperate, and C9350 switches do not accept Catalyst 9300 Series cables. STACK-T3A-50CM runs StackWise-320 on Catalyst 9300L and 9300LM with C9300L-STACK-A. A C9350 stack takes STACK-T1A-50CM.
  • Can STACK-T3A-50CM be coiled?

    No. Per the Catalyst 9300 hardware installation guide, STACK-T3A-50CM has a 41 mm bend radius and cannot be coiled. The 0.5 m cable must run straight between adjacent members with no slack to manage.
  • From which IOS XE release is STACK-T3A-50CM supported?

    Support for STACK-T3A-50CM and the C9300L-STACK-A adapter starts with Cisco IOS XE Cupertino 17.9.x. The cable is the default cable of C9300L-STACK-KIT2 and joins stacks of up to eight Catalyst 9300L or 9300LM switches.
  • Which spare PID orders a replacement STACK-T3A-50CM?

    The spare PID is STACK-T3A-50CM=. The Catalyst 9300 data sheet lists it with the STACK-T3A cable spares for C9300L-STACK-KIT2. Order the spare with the equals sign for a damaged 0.5 m (1.64 ft) StackWise-320 cable.
