Removable components

The S5120V3-30MS-UPWR-DP-EI switch uses the modular design and supports the following removable components.

Table 10 Removable components

Removable component model	S5120V3-30MS-UPWR-DP-EI
Removable power supplies
PSR360-56A	Supported
PSR720-56A	Supported
PSR1100-56A	Supported
PSR560-56D	Supported

You can install one power supply, or two power supplies for redundancy on the S5120V3-30MS-UPWR-DP-EI switch. Ensure uninterrupted power supply when only one power supply is present. The PoE power capacity of the switch varies by power supply configuration. For more information, see Table 4. The PoE capacity of the switch degrades when a power supply is faulty.

The removable components available for the S5120V3-30MS-UPWR-DP-EI switch are subject to change over time. For the most recent list of removable components for the switch, see the release notes.

NOTE:

To view electronic label information of the S5120V3-30MS-UPWR-DP-EI switch, execute the display device manuinfo power command.

Combo interface

The S5120V3-28P-HPWR-LI and S5120V3-28S-HPWR-LI switches each provide four combo interfaces on the front panel. The S5120V3-12TP-HPWR-LI switch provides two combo interfaces on the front panel. A combo interface contains an SFP port and a 10/100/1000BASE-T autosensing Ethernet port. Only one of these two ports can operate at a time.
