Description

This Cisco StackWise stacking cable joins Cisco Catalyst 3750 Series switches into a single stack through the dedicated StackWise ports on the rear panel. At 3 m (9.8 ft) it is the longest of the three StackWise cable lengths Cisco approves, which are 50 cm, 1 m and 3 m.

The extra length suits stacks where switches sit further apart in a rack or are spread across rack positions, where the shorter 50 cm and 1 m cables will not reach. On the Catalyst 3750 Series, StackWise provides a 32 Gbps stack interconnect and supports stacks of up to 9 switches. Stacking uses the dedicated StackWise ports, so no user ports are consumed.

Cabling every switch to both of its neighbours gives full bandwidth and redundant connections. This is a passive cable with no power draw and no licence requirement. It is designed for StackWise on the Catalyst 3750 Series and is not compatible with StackWise-480 or StackWise-160 cables.

FAQs

Q: Does this cable need a licence or power?
A: No. It is a passive cable with no power requirement, no PoE function and no licensing.

Q: Which switches does it work with?
A: It is an approved StackWise cable for the Cisco Catalyst 3750 Series. It is not compatible with StackWise-480 cables such as STACK-T1-xx used on the Catalyst 3850, or with StackWise-160 cables.

Q: How does it differ from the other StackWise cable lengths?
A: The functionality is the same across the family. CAB-STACK-3M is the 3 m length, while CAB-STACK-50CM and CAB-STACK-1M are the shorter 50 cm and 1 m versions for switches mounted closer together.

Q: Does stacking use up switch ports?
A: No. Stacking uses the dedicated StackWise ports on the rear panel, so all user ports remain available.

Q: Should every switch in the stack be cabled to two neighbours?
A: Yes. Cabling each switch to both neighbours gives full stack bandwidth and redundant connections. A stack with incomplete cabling runs at half bandwidth with no redundancy.
