All productsHuawei MA5800 series GPON service board GPHF and GPUF have different function, but with almost same appearance export for the board name label on the handle bar. Since GPUF is lower performance than GPHF, also lower price than GPHF; To earn more, some suppliers change GPUF label and configuration info to GPHF, then deliver customers GPHF nominally, actually it is GPUF functionally.
GPUF and GPHF both currently have two versions:
H901GPUF, H902GPUF;
H901GPHF, H902GPHF
H901GPUF and H901GPHF have same appearance (location of chips, radiator and circuit element are same), H902GPUF H902GPHF has same appearance.
Here we take H901GPUF H901GPHF for an example.
Huawei original H901GPUF
Huawei original H901GPHF
You can see above pictures, appearance of GPHF and GPUF are totally same. The label on Huawei original H901GPUF flat board even shows GPHF, just the labels on the front panel and handle bar show GPUF. So the dishonest supplier changes these two labels and change the configuration info on MA5800, and cheat customers in this way.
Then how to definitely identify GPHF and GPUF?

From the comparison list, GPHF and GPUF are different in MAX MAC address, 9K Jumbo frames, HQoS, PON ISSU and D-CCAP. Most of these differences only can be identified during use on site and cannot to be shown in OLT system, but you can check two boards’ 9K Jumbo frames according to the steps in the following to distinguish them.
1, insert GPHF and GPUF, power on MA5800 (we do the test on MA5800 X17)
2, Login MA5800 via Secure CRT
3, “display board 0”
MA5800-X17(config)#display board 0
{ <cr>||<K> }:
Command:

4, Confirm board in slot 5, 11 and 13
MA5800-X17(config)# board confirm 0/5
0 frame 5 slot board confirms successfully
MA5800-X17(config)# board confirm 0/11
0 frame 11 slot board confirms successfully
MA5800-X17(config)# board confirm 0/13
0 frame 13 slot board confirms successfully
5, Check board jumbo-frame
MA5800-X17(config)#interface gpon 0/5
MA5800-X17(config-if-gpon-0/5)#jumbo-frame 0 enable
Failure: The board does not support this operation
MA5800-X17(config-if-gpon-0/5)#interface gpon 0/11
MA5800-X17(config-if-gpon-0/11)#jumbo-frame 0 enable
MA5800-X17(config-if-gpon-0/11)#interface gpon 0/13
MA5800-X17(config-if-gpon-0/13)#jumbo-frame 0 enable
You can see board in slot 5 GPUF does not support jumbo-frame, while GPHF in slot 11 and 13 support.
So if you plan to purchase GPHF, confirm with the suppliers that it is real GPHF or fake GPHF; and if one supplier’s quotation is much lower than market price of other suppliers’ price, you need to double check because GPHF and GPUF price both increased due to less and less stock in the market.
