HP Switch part numbers
We need to connect two sites via single-mode fiber that's already in place. Network traffic will be minimal. We're looking at a pair of HP 2510 switches (part J9279A).
My question is related to the fiber modules. Two part numbers are given:
HP X112 100M SFP LC BX-D Transceiver (J9099B)
HP X112 100M SFP LC BX-U Transceiver (J9100B)
I'm not familiar with the concept of upstream/downstream when it comes to SFP modules. Reading the part descriptions it mentions using a single strand of fiber; I'm guessing this is the reason for the upstream/downstream parts?
I figured we would need one of each part number but wanted some expert feedback.
Thanks!

Glad I helped :)
not that fussed about the point but this is a little confusing
"#a40764802 (0 points) as the solution for the following reason:
Both real-world and vendor specs quoted in answer, answered question clearly and quickly."
no points for answering the question correctly and clearly and quickly? or is the system playing up?
has it had a long day like me?

Yeah, that was definitely not my intention. It showed 500 points when I closed.
More fully...
I don't use EE a lot, but in the past I remember an option to select the number of points when the question was created.
I didn't see that this time, but went ahead anyway.
When I closed the question, I saw 500 points at the top, and though "ok, it's different now, but the points are still there"
Apparently not though. Can a mod clear this up for us?

I thought my comment was going to a mod lol
I think there is a little bug in the system at the moment it's happened a couple times where a question was closed with no points then actually closed with points.
Like i said I’m not fussed and the comment you made looked applicative :)

re-accepting solution. I'm seeing 500 points awarded, just like yestreday.
