Power Supplies

The S5000 supports two hot-swappable PSUs.

The S5000 has SKUs that support the following congurations:

• AC PSU with fan airow from I/O to Utility

• AC-R PSU with fan airow from Utility to I/O

• DC PSU with fan airow from I/O to Utility

• DC-R PSU with fan airow from Utility to I/O

PSUs are eld replaceable. To ensure power redundancy and adequate cooling, install two power supplies in the switch. When

running with full redundancy (two PSUs installed and running), you can remove and replace one PSU while the other PSU is running

without disrupting trac.

NOTE: You can swap the fans and PSUs with fans/PSUs in the opposite airow direction (from I/O to Utility or from

Utility to I/O). However, do not mix directions in a single chassis. All the fans and PSUs must ow in the same direction.

If you create a mixed airow conguration, the software noties you of the invalid conguration.

Fans

The S5000 supports two hot-swappable fan trays with airow directions from I/O to Utility or Utility to I/O.

The S5000 has SKUs that support the following congurations:

• Fan with airow from I/O to Utility

• Fan-R with airow from Utility to I/O

NOTE: You can swap the fans and PSUs with fans/PSUs in the opposite airow direction (from I/O to Utility or from

Utility to I/O). However, do not mix directions in a single chassis. All the fans and PSUs must ow in the same direction.

If you create a mixed airow conguration, the software noties you of the invalid conguration.
