Glossary

Maximum PoE+ W Average PoE+ W on 12 ports

1835 W with two power

supplies

• VSP 4450GSX-PWR+ can support 802.3af 17.8 W or 32.4 W on each port with one power

supply installed. You can add a second power supply for redundancy.

supply installed. You can add a second power supply for redundancy.

Input/output port redundancy

You can protect I/O ports using a link aggregation mechanism. MultiLink Trunking (MLT), which is

compatible with 802.3ad static, provides a load sharing and failover mechanism to protect against

module, port, fiber, or complete link failures.

You can use MLT with Link Access Control Protocol (LACP) disabled or use LACP enabled by itself.

Configuration redundancy

You can define primary and backup configuration file paths. This configuration protects against

system failures. For example, the primary path can point to system flash memory and the backup

path to the external Compact Flash card.

Platform redundancy
