Basic Information | |
Description | S5731-L16P2SR-RUA(16*10/100/1000BASE-T ports, 2*GE SFP ports, PoE+, Fanless, AC power) |
Part Number | 98012157 |
Model | S5731-L16P2SR-RUA |
First supported version | V200R022C10 V600R022C10 |
Remarks | The RU itself does not have a software version. Instead, the first supported version of the RU depends on the software version of the central switch and varies for central switches running V200 and V600. |
