Power supplies
The following power supplies can be installed in the 2930M switches:
• Aruba X371 12VDC 250W 100-240VAC Power Supply (JL085A): A 250 watt power supply for the non-PoE
switches. This power supply does not provide any PoE power. It is keyed so that it will not fit into the power
supply slots of 2930M PoE switches.
• Aruba X372 54VDC 680W 100-240VAC Power Supply (JL086A): A 680 watt power supply for 2930M PoE
supported switches. This power supply offers up to 370 watts of PoE+ power. It is keyed so that it does not fit
into the power supply slots of non-PoE 2930M switches.
• Aruba X372 54VDC 1050W 110-240VAC Power Supply (JL087A): A 1,050 watt power supply for 2930M
PoE supported switches. This power supply offers up to 740 watts of PoE power. It is keyed so that it does not
fit into the power supply slots of non-PoE 2930M switches.
For initial power supply installation, see the Aruba 3810M/2930M Switch Power Supply Quick Setup Guide and
Safety/Regulatory Information that was shipped with the power supply units.
For more power supply information, see (Optional) Installing a second power supply.
Power connector
The 2930M switches do not have a power switch. They will power on when either one or both power supplies are
connected to an active AC power source.
Stacking module slot
Each of the 2930M switches has one module slot that can accept the following:
• 2930M Stacking Module (JL325A)
• 2920/2930M 0.5m Stacking Cable (J9734A)
• 2920/2930M 1.0m Stacking Cable (J9735A)
• 2920/2930M 3.0m Stacking Cable (J9736A)
These components provide high-speed connectivity to other 2930M switches. Only the 2930M switches support
this module.
Uplink port slot and module support
The 2930M family of switches features a module slot that allows the user to customize the uplink ports on the
switch. The slot support 40Gbps of maximum bandwidth and is available in three possible options: four Smart
Rate, four SFP+, or one QSFP+.
NOTE: Unsupported modules are mechanically prevented from installing into unsupported slots.
