HiPath 4000 HUB C question

[ccmjgb]

Greetings,

Need clarification on a HiPath's Hub C. Currently the HiPath 4000 system includes host, ipda (in different building), and 1 additional shelf in a room next to host.

Shelf 21 is currently patched in to a layer 2 switch that is used to network Node 1 (host) and Node 2 (IPDA in different building) via fiber modules. This layer 2 switch is sitting in the room next to the host, where shelf 21 is located - shelf 21's nciu card plugs in to this layer 2 switch. However, there are spare ports avaialable on the HUB C card of the host and would like to run a patch cord from shelf 21 and directly connect to one of these spare ports instead of connecting to the layer 2 switch. Is this it a simple matter of re-patching to an avaiable HUB C port? or is there any other config needed (e.g. shut / no shut)?

The idea is to minimize unnecessary IP traffic on these layer 2 switches that carry traffic between nodes. There have been several IP payload problems that surface every few months eventually resulting in loss of voice between nodes and want to clean up everything possible.

Thank you!

Is this a very old system, consisting of a large cabinet with the bottom shelf containing the ADP (far left), SWU-A (middle) and SWU-B (far right)?
If so, then there probably is a Hub-C board beside the ADP processor. The Hub-C is for Atlantic LAN only. You 100% cannot use the Hub-C for IPDA connectivity.

If your system is based on a cPCI shelf - six slots, horizontally-mounted DSCXL processors - then (if Duplex) there should be a board in slot 6 called the "Switch Fabric" board (SF2x8). If THAT is what you are referring to as the "Hub-C", then you can use the 8-port switch for IPDA connectivity - as long as there is only one subnet plugged in to that 8-port switch. It is a non-programmable customer switch.

If you re-post and clarify, I will try to add more info.

The description matches the cPCI platform... all horizontal cards

SLOT 6: 2 Atlantic ports, 8 customer ports (4 used: 1 processor A, 1 standby processor, 1 apps processor, 1 uplink)
SLOT 5:
SLOT 4: standby processor
SLOT 3:
SLOT 2: processor A
SLOT 1: applications processor


one of the customer ports in slot 6 is uplinked to the layer 2 switch (or hub) in the next room where shelf 21 now sits. So based on your thoughts, it should be ok to run a new patch cable from shelf 21 and directly patch into port 5 of SLOT 6

Yes, that should work. However, I do not recommend using it. I experienced odd problems using that "built-in" customer switch. I no longer use it. Perhaps that was the exception, though. You never know!
