How do I test a Cisco switch power supply?
Use the show environment status command to check the power supply status. You can use the power supply EXEC command to configure and manage the internal power supply on the device. The device does not support the no power supply EXEC command. A —Selects the power supply in slot A.
How does Cisco VSS work?
In VSS mode, supervisor engine redundancy operates between the active and standby chassis, using stateful switchover (SSO) and nonstop forwarding (NSF). The peer chassis exchange configuration and state information across the VSL and the standby supervisor engine runs in hot standby mode.

How do you turn off a Cisco 6500 module?
If you enter the ‘hw-module shutdown’ command to shut down the module, you will have to enter the ‘no power enable module’ command and the ‘power enable module’ command to restart (power down and then power up) the module.
How much power does a Cisco switch use?
With a single 1,150-watt power supply, one switch consumed around 141 watts idle and 150 watts fully loaded.
How do I check my power supply status?
Test the power supply with a power supply testing unit.
- Connect the power supply testing unit to the 20/24 pin connector.
- Plug the power supply back into the outlet and turn it on.
- Check the voltages.
- Ensure that the voltages are within normal accepted tolerances.
- Test the other connectors.
What is difference between VSS and vPC?
VSS is the 6500 technology to logically combine two physically separate chassis. As you point out vPC is a Nexus technology, the Catalyst equivalent is MEC (Multi-chassis Ether Channel). From your message you are correct in thinking that using etherchannel from the TOR switches to the core is the correct solution.
What is difference between stack and VSS?
A VSS will allow two physical Cisco Catalyst Series Switches to operate as a single logical virtual switch called a virtual switching system.
…
Comparison Table: Stacking vs VSS.
| FEATURE | STACKING | VSS |
|---|---|---|
| Distance Supported | Limited by distance | VSS members can be in geographically distant locations |
What is a Cisco chassis?
Chassis Overview
The 8-slot chassis is a half-height, rack-mounted 8-slot version of the Cisco CRS 16-Slot Line Card Chassis router. The routing systems are built around a scalable, distributed three-stage switch fabric and a variety of line card (packet) interfaces.
Does WS X6748 GE TX support PoE?
Product Description. The Cisco Catalyst X6748-GE-TX PoE module provides intelligent power management such that it negotiates power requirements with Cisco powered devices using Cisco Discovery Protocol.
How do you turn off a Cisco 4500 module?
“hw-module module x shutdown “, this command used to completely power down the particular module.
What Cisco command can you use to display the hardware modules that are installed in the Cisco device vand the serial number of each hardware component?
Use the show hw-module subslot command in Cisco 4400 Series ISRs to obtain diagnostic information related to all supported Cisco services modules and network interface modules(NIM).
How do I calculate power consumption of a switch?
To calculate maximum system power consumption, you first determine the combined maximum internal power requirements of all the switch components and then divide this result by the power supply efficiency.
How much power does a switch consume?
Switches don’t actually consume too much power, which may be surprising given how capable of a device they are. It does vary depending on the manufacturer, the model, and how many ports are available and in use, but you can typically expect a switch to use between 15 and 30 watts to operate.
How do I know if my power supply is failing?
Signs of a Failing PSU
- PC Won’t Boot at All. As the central hub of the energy of your computer, if the power supply has died, the computer will fail to start.
- PC Randomly Restarts or Shuts Down.
- Random Blue Screen of Death (BSoD)
- Extra Noise Coming from the PC Case.
- Smoke or a Burning Smell.
How do I check my power supply voltage?
Switch your multimeter to the range that is appropriate for reading the voltage from your power supply. If your power supply’s voltage is 125 volts, switch your multimeter to read a range of 100-200 volts. Some multimeters may not offer a range, so you may need to choose the approximate voltage on a dial.
What is the benefit of VSS?
VSS reduces the complexity of the network architect. In traditional network architect, we have required the gateway’s redundancy configuration at the distribution/core layer by using FHRP.
What is the difference between VSS and stacking?
Stackwise Virtual and VSS are technically the same. They are called what they are because of marketing. In both instances, two physical chassis for a single logical unit which makes management easier and enables cross-chassis Etherchannel.
Does Cisco 9500 support VSS?
The 9500 series support Virtual Stacking, which is another name for VSS.
What is chassis switch?
A Chassis is a physical container or hardware in which all the switches are defined. Each chassis can be logically partitioned as more than one switch.
What is Cisco Aggregation switch?
Chassis aggregation is a Cisco technology to make two switches operate as a single logical switch. It is similar to stacking but meant for chassis switches like the 6500 and 6800 series switches. It is often used in the core layer and sometimes in the distribution layer.
What is GE TX?
Product Overview. The Cisco® Catalyst® 2948G-GE-TX Gigabit Ethernet Switch is a fixed-configuration switch that provides Gigabit Ethernet connectivity for small and medium-sized networks (Figure 1).
