G	Uplink port type: C: The product supports extended cards and its uplink ports are provided by an extended card or are fixed 10GE ports. PC: The product supports extended cards and its uplink ports are provided by an extended card or are fixed GE ports. X: The product has fixed 10GE uplink ports. TP: The uplink ports of the product include combo ports consisting of electrical and optical ports. P: The uplink ports of the product are fixed GE optical ports.

H	PWR: The product supports Power over Ethernet (PoE). PWH: The product supports PoE++. NOTE: If the product name does not contain this field, the switch does not support PoE.
I	Level type: LI: lightweight version SI: standard version EI: enhanced version HI: high-level version, which supports high-performance operation, administration, and maintenance (OAM) and built-in real-time clock (RTC)
J	Downlink port type: 24S: 24 downlink SFP optical ports 48CS: 48 downlink compact SFP (CSFP) optical ports NOTE: If the product name does not contain this field, all downlink ports of the switch are electrical ports.
K	Power supply type: AC: switch using AC power supply AC1 or ACF: switch using AC power supply and supporting high-power PoE power modules ACL: switch using AC power supply and having a built-in low-power PoE power module DC: switch using DC power supply BAT: battery LAN switch NOTE: Some product models that support pluggable power modules are sold with AC or DC power modules (standard configuration), and their product names contain "-AC" or "-DC". However, the silkscreen or nameplate on the chassis does not contain "-AC" or "-DC". For example, the S5720-56C-HI supports pluggable AC and DC power modules. If its standard configuration includes AC power modules, its product name is S5720-56C-HI-AC, but the name on its silkscreen or nameplate is still S5720-56C-HI.
