Generation 1 and Generation 2 Issues Chapter 5 Troubleshooting Mixed Generation Hardware Send documentation comments to [email protected] Module Does Not Come Online Symptom Module does not come online. Table 5-8 Module Does Not Come Online Symptom Module does not come online. Possible Cause Not enough port indexes are available. Available port indexes are non-contiguous. Not enough power is available in the chassis. Solution See the "Verifying Port Index Allocation Using Device Manager" section on page 5-8 or the "Verifying Port Index Allocation Using the CLI" section on page 5-9. If the switch has Generation 1 modules inserted, upgrade to all Generation 2 modules to gain higher total port index availability. See the "Verifying Port Index Allocation Using Device Manager" section on page 5-8 or the "Verifying Port Index Allocation Using the CLI" section on page 5-9. Use the show environment CLI command to determine if you have enough available power for the module. Upgrade your power supply, if necessary. Verifying Port Index Allocation Using Device Manager To verify port index allocation using Device Manager, follow these steps: Step 1 Choose Interfaces > Show Port Index Allocation > Current to display the allocation of port indexes on the switch. Module index distribution: Slot | Allowed | Alloted indices info | | range | Total | Index values | 1 | 0- 255| 16 | 32-47 | 2 | 0- 255| 12 | 0-11 | 3 | 0- 255| - | (None) | 4 | 0- 255| - | (None) | 7 | 0- 255| - | (None) | 8 | 0- 255| - | (None) | 9 | 0- 255| - | (None) | SUP | ----- | 3 | 253-255 | In some cases, the sequence in which switching modules are inserted into the chassis determines if one or more modules is powered up.
