Hw-module Slot
Hw-module subslot card slot/subslot number shutdown unpowered. Example: Device(config)# hw-module subslot 1/0 shutdown unpowered: Powers down the specified module by placing it in low power mode. Example: Device(config)# end: Exits the global configuration mode. Hello All, I need help on the explanation from 'show hw-module' output for below particular section (bold) of the output. What does the output mean? I try to search for document but couldn't find any. And from the command, how do I verify the operating distance that the SFP supported? Although graceful deactivation of a SIP is preferred using the hw-module slot stop command, the Cisco Aggregation Services Router 1000 Series do support removal of the SIP without deactivating it first. If you plan to remove a SIP, you can deactivate the SIP first, using the hw-module slot stop command in global configuration mode.
The Catalyst 6840-X-LE-40G and 6824-X-LE-40G have two native 40-Gb ports.
These ports can be converted to 8x10G ports, starting from Cisco IOS Software Release 15.2(2) SY2, by simply changing the operation mode from ‘FortyGigabitEthernet mode’ to ‘TenGigabitEthernet mode’. The following output provides an example.
Note:Changing the operation mode will reset the whole chassis; all 40G ports configuration will be lost.
Performance Mode
The Cisco Catalyst 6840-X Series has two performance modes: oversubscription mode and performance mode.
No Hw-module Slot 1 Oversubscription
Note that these modes affect port groups rather than an individual port.
By default, the module operates in oversubscription mode since a backplane capacity of 80 GB per DFC4-E feeds 16×10 Gigabit Ethernet ports, resulting in a 2:1 oversubscription ratio.
The default port performance mode can be identified using a show command:
Performance mode can be enabled by issuing a configuration command that will result in shutting down certain ports in the selected port group so as to make the port-to-fabric bandwidth come down from 2:1 to 1:1. The second half of the port group will be disabled when configuring performance mode. (for instance, configuring port group 2 on the Catalyst 6816-X-LE will disable ports 13, 14, 15, and 16, and will be available on ports 9, 10, 11, and 12. The ratio will be a 1:1 port-to-fabric bandwidth.
The Catalyst 6840-X series chassis provides extremely high levels of scalability and performance, with the size and economics of an innovative fixed architecture. This unique platform offers 10-Gb port density; full IPv4/IPv6 and MPLS/VPLS functionality with large table sizes (up to 256,000 Forwarding Information Base [FIB] entries); and more than 15 years of best-in-class features.

With a full suite of Layer 2 and 3, virtualization, security, multicast, IPv6, application visibility, smart operations, and rich media services, the Cisco Catalyst 6840-X delivers superior capabilities from its first day of deployment.
