PoE+ and PoE++ Power Budgets
The PoE+ and PoE++ power budgets of the GS980MX/28PSm,
GS980MX/52PSm, and GS980MX/10HSm Switches are listed here.
Power budgets are the maximum amounts of power that PoE
switches can provide to powered devices on the Ethernet copper
ports.

GS980MX/10HSm
GS980MX/28PSm
GS980MX/52PSm
The GS980MX/10HSm Switch supports IEEE 802.3bt PoE++
Classes 0 to 8 devices. (Maximum 90.0W at the switch ports.)
The GS980MX/28PSm and GS980MX/52PSm Switches support
IEEE 802.3at PoE+ Classes 0 to 4 devices. (Maximum 30.0W at the
switch ports.)
VCStack
™
The VCStack feature is used to manage up to four GS980MX
Switches as a single virtual unit. The switches synchronize their
actions so that switching operations (such as spanning tree
protocols, virtual LANs, and static port trunks) span across all the
ports and switches. Two advantages of stacks are:
You can manage multiple units simultaneously, which can

simplify network management.
You can add redundancy to your network topology by distributing

functions across multiple switches. For instance, static port
trunks on standalone switches have to consist of ports from the
same switch. In contrast, static port trunks in a stack can have
ports from different switches.
Note: For instructions, refer to the GS980MX Series Installation
Guide for Virtual Chassis Stacking.
