Brocade 4900 and HP2 8GB SAN Switches

Hi everyone.  I'm brand new to fiber channel switches.  I'm trying to connect an 8GB blade chassis san switch to my existing brocade 4GB 4900 fabric.  It's giving me nothing but errors.  No matter if I change cables, ports, modules, etc it always settles into this pattern:

Brocade side:

RX Power:    -40.0  dBm (0.1 uWatts)

TX Power:    -4.6  dBm (349.8 uWatts)

Chassis side:

                                          Alarm                  Warn

                                      low        high       low         high

Temperature: 31      Centigrade     -15         100        -10         95

Current:     0.002   mAmps          2.000       8.500      2.000       8.500 

Voltage:     3273.0  mVolts         2800.0      3800.0     2970.0      3630.0

RX Power:    -5.0    dBm (316.8 uW) 0.0    uW   6550.0 uW  49.0   uW   1100.0 uW

TX Power:    -40.0   dBm (0.1   uW) 50.0   uW   800.0  uW  100.0  uW   700.0  uW

The chassis switch is fab os version: 6.3.2e and the brocade 4900 is 6.2.2f.  Are these two products compatible? 

Brocade side:

fc64sw101d:root> portcfgshow 14

Speed Level:  4G

Fill Word:  0(Idle-Idle)

AL_PA Offset 13:  OFF

ISL R_RDY Mode  OFF

QOS E_Port  OFF

Chassis side:

Fill Word:  0(Idle-Idle)

AL_PA Offset 13:  OFF

Any help would be really appreciated.  I'm stuck as to why these are not talking to one another.  HP support said their chassis switch was completely fine.

Hello,

--->>> I'm trying to connect an 8GB blade chassis san switch to my existing brocade 4GB 4900 fabric.

check please Both ( Blade and 4900) Domain ID, keepin mind each switch in the Fabric must have unique Domain ID,

switchshow command output can you see the current domain ID in both switch.

From you post, show as the 4900 is productive, in such case if both have same DID you shold change DID in new non-productive switch.

Another problem, make sure both have compatible FOS release.

Re: Brocade 4900 and HP2 8GB SAN Switches

switchshow says the domain id's are unique, so that's good.  How would I check to see if the FOS releases are compatible?  I originally had both on 6.2.2f but that didn't work so I tried upgrading the 8Gb chassis switch to 6.3.2e.  No luck there either.

Hi,

to check if releases are compatible you need to read the release notes (so check the one from 6.3.2e if it says that it's compatible with 6.2.2f).

Also portdisable;portenable on the ISL port can often help.

TX Power:-40.0

This SFP is nearly not transmitting enough.
