Power cords specifications (ordered separately):

Tip:

It is recommended to use straight-ended power cords for use with the retention clip, and to avoid blocking other ports with third party right-angled cables.

Danger:

Use AC power cords that have a ground wire (if applicable). If you use power cords without a ground wire, ensure the switch is properly grounded before powering on the unit. Without a proper ground, you are in danger of receiving an electrical shock. Lack of a grounding path to the switch can result in excessive emissions.

VSP 8608 chassis

The VSP 8608 chassis provides eight slots for I/O and control (IOC) modules and three slots for switch fabric (SF) modules in a 7U vertically oriented configuration. The chassis supports four power supplies, and includes five preinstalled cooling modules, each with 2x80 mm fans. For more information, see Hardware Component Specifications and Part Numbers on page 12.

The following figure shows the slot designations for the VSP 8608 chassis. From left-to-right, slots 1 through 4 are designated for I/O and control (IOC) modules, followed by slots SF1 through SF3 for switch fabric modules, and then slots 5 through 8 for IOC modules.

Warning:

Keep the metal cover plate in place over empty module slots. An empty module slot allows air into the chassis, which reduces the negative pressure in the chassis. This reduces airflow to the installed modules.

The following figure shows an example of a populated VSP 8608 chassis with four IOC modules in slots 1 through 4, a switch fabric module in slot SF1, and four AC power supplies.

Cooling modules

Cooling modules

The chassis includes five cooling module slots. The cooling modules plug directly into the backplane at the rear of the chassis. Each module contains 2 x 80 mm fans. The backplane connects the fan control signals to the I/O and control (IOC) slots.

Note:

This document uses the term cooling module to refer to the cooling fans within the VSP 8608 chassis. The terms fan, fan tray, and cooling unit (CU) also refer to the cooling fans within the chassis.

The following figure shows the rear of the chassis with five cooling modules. Facing the rear, the cooling modules are numbered CU1 through CU5 from left-to-right. The airflow direction is from

front-to-back. To ensure uniform airflow across all module slots, the fans in each cooling module create a negative pressure that is evenly distributed across an internal plenum.

Danger:

Risk of personal injury

When you remove a cooling module, allow time for the fans to spin down before you fully withdraw the cooling module. Be careful to keep your fingers out of the fan blades.

Fan speed

Inside the chassis, there are thermal sensors that monitor the temperature. The temperature readings of the sensors send information to the central controller that automatically adjusts the cooling module fan speed to maintain the proper temperature. For example, when the temperature reading of the sensors decreases, the cooling module fan speed also decreases, which helps to minimize fan noise. However, if one of the cooling modules fail or is temporarily removed, the speed of the other cooling modules increase to their maximum rotational speed, which provides maximum cooling to the chassis. The chassis can operate with a single cooling module failure and still

Cooling modules

maintain uniform airflow across all module slots. When all cooling modules are operational, the internal temperature sensors determine the speed of the fans.

Warning:

Do not operate a chassis for more than a few minutes with a missing cooling module. To ensure internal chassis air pressure is maintained and to avoid loss of traffic due to modules overheating and shutting down, leave a failed cooling module installed until you have a replacement.

Alarms are triggered when the temperature exceeds the following alarm thresholds—Warning, Critical, and Shutdown.

Note:

%d represents a number for either a sensor, slot, or temperature. The following list shows the log messages for the three threshold types:

•Warning—Temperature Sensor %d is (%d C) has exceeded the alarm threshold temperature (%d C).

•Critical—Sensor %d slot %d temperature (%d C) exceeded the critical alarm threshold (%d C). Module will be shut down at (%d C).

•Shutdown—Sensor %d in slot %d temperature (%d C) exceeded the shutdown threshold temperature (%d C). Module has been powered down.

Alarms are cleared when the temperature cools by 2° below the threshold temperature. The following list shows the log messages when an alarm is cleared:

•Critical threshold—Sensor %d in slot %d overheat critical alarm cleared

•Warning threshold—Temperature Sensor %d overheat temperature alarm cleared

You can use the following command to monitor current temperature, and view the threshold values for Warning, Critical, and Shutdown.

The following table provides a description of the various threshold limits:

Table 1: Alarm thresholds

	Value	Description
	Sensor Index	Specifies sensor IDs from 1 to 5. There are five sensors on each module.
	Current temperature	Specifies the current temperature sensor reading.
	Warning threshold	Specifies the temperature at which an alarm is raised.
	Critical threshold	Specifies the point at which a log message is generated. Action must be taken at
		this point otherwise the module is at risk of reaching the shutdown threshold.
	Shutdown threshold	Specifies the critical maximum value where the module shuts down.

Hardware fundamentals

Value	Description
	Note:
	If a module enters a shutdown state, upon return to normal state, the
	module must be powered on.
	Normal state is when the temperature is below the Warning threshold value,
	and there is no alarm on the system.

Important:

In a situation where there is a single module in either IOC slot 1 or 2 that runs the control plane (CP) software and the module reaches the maximum value, the switch shuts down. If redundancy is in place where there are modules in both IOC slots 1 and 2, and one of these modules reaches the maximum value, the switch remains operational.

IOC Modules

The input/output and control (IOC) modules occupy slots 1 through 4 and slots 5 through 8.

The front panel on each IOC contains an RJ–45 console port, OOB Ethernet management port, USB port, and status LED indicators.

Electrostatic alert:

ESD can damage electronic circuits. Do not touch electronic hardware unless you wear a grounding wrist strap or other static-dissipating device.

Warning:

Keep the metal cover plate in place over empty module slots. An empty module slot allows air into the chassis, which reduces the negative pressure in the chassis. This reduces airflow to the installed modules.

You can power on the chassis before or after the modules are installed. However, you must have an IOC module in either slot 1 or slot 2 for the system to operate. For redundancy purposes, you must have an IOC module in both slots 1 and 2. The IOC modules in slots 1 and 2 run control plane (CP) software, as well as I/O software for the local ports on the IOC module. The modules are hot swappable. Install a filler panel in any unpopulated IOC slot.

Note:

For part numbers (including Trade Agreement Act (TAA) compliant part numbers), see Hardware Component Specifications and Part Numbers on page 12.

The chassis supports the following IOC modules:

MACsec Support for IOC Modules

The following table identifies the IOC modules that offer hardware and software MACsec support.

8616QQ	No	No	N/A
8606CQ	Yes	Yes	128bit and 256bit

Note:

MACsec is not supported on channelized ports.

Channelization support

Channelization allows to configure a single port to operate as four individual ports. Channelization can apply to the following port speeds:

•40 Gbps (QSFP+) — when channelized, operates as four 10 Gbps ports

•100 Gbps (QSFP28) — when channelized, operates as four 25 Gbps ports

Channelization on the 8616QQ module

The 8616QQ module supports channelization on the first four ports only. By default, the ports are not channelized, which means that the 40 Gbps QSFP+ ports operate as 40 Gbps ports. You can

September 2018

Installing the VSP 8600

23

Hardware fundamentals

enable or disable channelization on any of the first four ports. Ports 5-16 do not support channelization.

Channelization enables you to configure 40 Gbps QSFP+ ports to operate as four separate 10 Gbps ports. You can use either 40GBASE-CR4 (copper) or 40GBASE-SR4 (fiber) breakout cables to connect the 10 Gigabit Ethernet ports to other servers, storage devices, and switches. For breakout cable details, see Installing Transceivers and Optical Components on VSP Operating System Software.

Channelization on the 8606CQ module

The 8606CQ module supports channelization on all six 100 Gbps ports. The channelized port can operate as four 25 Gbps ports if QSFP28 cables are used or four 10 Gbps ports if QSFP+ cables are used. This allows the 100 Gbps port to operate as a 40 Gbps port with the sub-ports operating at 10 Gbps speed. You can use 40GBASE-CR4 (copper) or 40GBASE-SR4 (fiber) or 100GBASECR4 (copper) or 100GBASE-SR4 (fiber) breakout cables to connect the 40/100 Gigabit Ethernet ports to other servers, storage devices, and switches.

By default, the ports are not channelized. If channelization is not enabled, the ports display the existing port format as “slot/port”. Once channelization is enabled, ports display the format as “slot/ port/sub-port” in the input/output.

MACsec is not currently supported on the channelized 10G/25G ports on the 8606CQ. If a MACsec enabled port is channelized, then the MACsec configuration on that port will be lost.

Considerations

•10 Gbps ports may indicate a link up state error, which represents a misconfiguration and can create a black hole for packets. This can only happen if all of the following conditions are true:

-A QSFP+ with a fiber breakout cable is installed in a 40 Gbps port.

-The 40 Gbps port connected to the breakout cable is not yet channelized.

-The 40 Gbps port is administratively up.

-Any, or all, of the 10 Gbps ports connected to the other end of the breakout cable are administratively up.

To avoid this error, set the 40 Gbps port to administratively down prior to installing the channelization breakout cable.

FEC configuration support

Configure Forward Error Correction (FEC) on a port to obtain error control in data transmission over an unreliable or noisy channel. You can configure FEC on 100 Gbps ports or on channelized 100 Gbps ports operating at 25 Gbps speed.

The following FEC options are supported:

•Clause 91

•Clause 108

•Clause 74

September 2018

Switch fabric modules

FEC configuration on the 8606CQ module

The 8606CQ module supports FEC configuration on all six 100 Gbps ports and on channelized 100 Gbps ports operating at 25 Gbps speed. On a 100 Gbps port, only the Clause 91 and Clause 108 options are supported. On the channelized ports, you can configure either Clause 108 for extra latency or Clause 74 for reduced latency.

FEC is not supported on a 100 Gbps port operating at 40 Gbps speed or on a management port.

Important:

On ports that support FEC configuration, ensure that you configure the same option at both endpoints. Otherwise, the link does not come up.

For more information on FEC, see Administering.

MACsec Encryption Cipher Suites

The 8606CQ module supports configuration of a cipher suite for MACsec encryption. You can configure either the GCM-AES-128 cipher suite with a maximum key length of 128 bits, or the GCM- AES-256 with a maximum key length of 256 bits. The default cipher suite is the GCM-AES-128. The 256-bit algorithm provide enhanced security and includes the security provided by the 128-bit algorithm.

Note:

You cannot configure a MACsec cipher suite on a channelized port of the 8606CQ module. For more information on how to configure a cipher suite on a port, see Configuring Security.

Switch fabric modules

The three center slots are dedicated to switch fabric (SF) modules. Two SF modules provide enough switching bandwidth to accommodate all the populated modules (including the highest speed modules). The control processors (CP) on the SF modules provide functions such as fabric initialization and multicast table updates on the SF.

The processors located in IOC slots 1 and 2 use a gibabit-Ethernet connection to communicate with the switch fabric modules in slots SF1 through SF3. The modules are hot swappable.

The number of SF modules that you require for redundancy depends on the types of modules installed. Use the following examples to provide a guide for redundancy:

•If you have installed only 24 port, 10 Gbps IOC modules, you require two SF modules to provide 1+1 redundancy, where one SF module supports the bandwidth and the second SF module provides redundancy.

•If you have higher speed IOC modules (40 Gbps and 100 Gbps), you require two SF modules to support the bandwidth and a third SF module to provide 2+1 redundancy.

AC and DC power supply fundamentals

Port channelization

For ports that use channelization, use only breakout cables (copper direct attach cables (DAC) or fiber). Otherwise, the link behavior can be unpredictable due to mismatched link status between link partners, which can lead to additional network issues.

For non-channelized ports, do not use breakout cables.

AC and DC power supply fundamentals

The chassis supports four 3,000 watt AC power supply units or 2,500 watt DC power supply units. Each power supply is self enclosed and vents directly to the rear of the chassis; therefore, empty power supply bays do not need a filler panel. If the chassis has more than one power supply installed, you can hot swap a power supply on an operational switch.

You require one power supply to operate the chassis; however, the system software prevents some of the IOC modules from entering a fully operational state if there is insufficient power available. As you populate the chassis with more modules, additional power supplies might be required. Use the Power Calculator tool to assist with calculating the power available versus the power load.

Caution:

Use the power calculator to determine if your AC power supply units (PSU) provide the correct power capacity for your chassis configuration. In situations when your switch is heavily populated, it is preferred that you connect to a 240–VAC power source to provide each AC PSU with up to 3,000 watts. Or, in situations when your switch is lightly populated, you can connect to a 120–VAC power source to provide each AC PSU with approximately 1,400 watts.

Power calculator tool

Use the power supply calculator tool to help you determine the power requirement when configuring the chassis, I/O and control (IOC) modules, switch fabric modules, optical transceivers, and power supplies. This tool can be used to calculate the available power from the power supplies and the power consumption for each IOC and each populated port. The results provide typical and maximum power consumption, which helps you to determine your power reserve (power margin) to ensure you do not exceed the maximum power allotted for all power supplies.

Important:

You require a basic knowledge of the various transceiver types and quantities used with each line card. This tool does not alert you if port devices are incorrectly selected for a card or if incorrect quantities of port devices are selected.
