| • The module may not be receiving enough power. Brocade |
|
|
|
|
|
| recommends installing power supplies in a fully redundant |
|
|
|
|
|
| configuration as described for each router model in this |
|

|
|
|
|
|
| • Check the Pwr LED on the management module. If it is on, |
|
|
|
|
|
| the management module may be preventing power from |
|
|
|
|
|
| getting to the interface module. |
|
|
|
|
|
| • Enter the show chassis command at any level of the CLI to |
|
|
|
|
|
| determine if the management module recognizes the |
|
|
|
|
|
| presence of all power sources. |
|
|
|
|
|
| • If you are using AC power supplies, see the entry for the AC |
