About Modules
This table describes the supervisor module options for switches in the Cisco MDS 9000 Family.
Product | Number of Supervisor Modules | Supervisor Module Slot Number | Switching and Services Module Features |
---|---|---|---|
Cisco MDS 9513 | Two modules | 7 and 8 | 13-slot chassis allows any switching or services module in the other eleven slots. |
Cisco MDS 9509 | Two modules | 5 and 6 | 9-slot chassis allows any switching or services module in the other seven slots. |
Cisco MDS 9506 | Two modules | 5 and 6 | 6-slot chassis allows any switching or services module in the other four slots. |
Cisco MDS 9216 | One module | 1 | 2-slot chassis allows one optional switching or services module in the other slot. |
Cisco MDS 9216A | One module | 1 | 2-slot chassis allows one optional switching or services module in the other slot. |
Cisco MDS 9216i | One module | 1 | 2-slot chassis allows one optional switching or services module in the other slot. |
Supervisor Modules
Supervisor modules are automatically powered up and started with the switch. The Cisco MDS Family switches have the following supervisor module configurations:
-
Cisco MDS 9513 Directors—Two supervisor modules, one in slot 7 (sup-1) and one in slot 8 (sup-2). When the switch powers up and both supervisor modules come up together, the active module is the one that comes up first. The standby module constantly monitors the active module. If the active module fails, the standby module takes over without any impact to user traffic.
-
Cisco MDS 9506 and Cisco MDS 9509 Directors—Two supervisor modules, one in slot 5 (sup-1) and one in slot 6 (sup-2). When the switch powers up and both supervisor modules come up together, the active module is the one that comes up first. The standby module constantly monitors the active module. If the active module fails, the standby module takes over without any impact to user traffic.
-
Cisco MDS 9216i switches—One supervisor module that includes an integrated switching module with 14 Fibre Channel ports and two Gigabit Ethernet ports.
-
Cisco MDS 9200 Series switches—One supervisor module that includes an integrated 16-port switching module.
Module Terms | Fixed or Relative | Usage |
---|---|---|
module-7 and module-8 |
Fixed usage for the Cisco MDS 9513 Director |
module-7 always refers to the supervisor module in slot 7 and module-8 always refers to the supervisor module in slot 8. |
module-5 and module-6 |
Fixed usage for the Cisco MDS 9509 and Cisco MDS 9506 Directors |
module-5 always refers to the supervisor module in slot 5 and module-6 always refers to the supervisor module in slot 6. |
module-1 |
Fixed usage for the Cisco MDS 9200 Series switches |
module-1 always refers to the supervisor module in slot 1. |
sup-1 and sup-2 |
Fixed usage |
On the Cisco MDS 9506 and MDS 9509 switches, sup-1 always refers to the supervisor module in slot 5 and sup-2 always refers to the supervisor module in slot 6. On the Cisco MDS 9513 Directors, sup-1 always refers to the supervisor module in slot 7 and sup-2 always refers to the supervisor module in slot 8. |
sup-active and sup-standby |
Relative usage |
sup-active refers to the active supervisor module-relative to the slot that contains the active supervisor module. sup-standby refers to the standby supervisor module-relative to the slot that contains the standby supervisor module. |
sup-local and sup-remote |
Relative usage |
If you are logged into the active supervisor, sup-local refers to the active supervisor module and sup-remote refers to the standby supervisor module. If you are logged into the standby supervisor, sup-local refers to the standby supervisor module (the one you are logged into.) There is no sup-remote available from the standby supervisor module (you cannot access a file system on the active sup). |
Switching Modules
Cisco MDS 9000 Family switches support any switching module in any non-supervisor slot. These modules obtain their image from the supervisor module.
Services Modules
Cisco MDS 9000 Family switches support any services module in any non-supervisor slot.
