JMT ADT-R27 PCIe 5.0 / 4.0 x4 to U. 2/U. 3/E1. S/E3. S Hard Disk Adapter 128Gbps with Bracket Compatible with EDSFF Hard Disk Drive Bandwidth R27A, R27B: PCIe 4.0 x4
R27C: PCIe 5.0 x4 R27A, R27B and
R27C usage: Not compatible with each other, can`t be mixed. R27A is suitable for use with U. 2 hard disks. R27B is applicable with U. 3 hard disk. R27C works with E1. S hard disk and E3. S hard disk. U. 2 and U. 3 interfaces look the same but have different pin definitions and cannot be mixed, so please be careful to recognize them. Product Advantages. 1. Support PCIe 5.0 / 4.0 X4 Compatible with Gen3/Gen4/Gen5 2. Uniquely designed bracket base plate, perfect fit for U. 2/U. 3/E1. S/E3. S hard disk. 3. Gold-plated gold fingers, gold thickness up to 10U, in line with IPC level 1 international standards. 4. high-frequency, low resistance, high temperature and oxygen-resistant PCB board, no deformation of the color yellow crystal semi-transparent, not white, not black. Indicator light R27A and
R27B: D2 light for the power indicator, D1 light for reading and writing light, under normal circumstances, D1 light is always on, D2 light reading and writing state will blink.
R27C: Under normal circumstances, both D1 and D2 light are normally lit, of which D1 light will be lit as long as the device is in the power state, if you need to go out, please turn off the power.
