ExtremeSwitching VSP 4900 Series switches provide support that can be deployed in either Enterprise LAN or high-density, top-of-rack high-performance enterprise and aggregation applications. The switches also provide a modular Versatile Interface Module (VIM) slot that allows a user to choose an uplink model that is suitable for their needs. The VSP 4900 Series switches run the VOSS operating platform.
VSP 4900 Series switches include the following base models:
VSP4900-48P - switch with 3 fan modules and 2 unpopulated power supply slots
VSP4900-12MXU-12XE - switch with 3 fan modules and 2 unpopulated power supply slots
VSP4900-24S - switch with 3 fan modules and 2 unpopulated power supply slots
VSP4900-24XE - switch with 3 fan modules and 2 unpopulated power supply slots
The 10/100/1000BASE-T ports on the VSP 4900-48P model can operate in half-duplex mode when operating at 10Mbps or 100Mbps. In addition, this model supports IEEE 802.1AE MACsec.
The following Versatile Interface Module (VIM) are available for VSP 4900 series switches:
VIM5-4X versatile interface module that provides four 10-GbE (SFP+) ports.
VIM5-4XE versatile interface module that provides four 10-GbE (SFP+) ports, LRM/MACsec capable.
VIM5-2Y versatile interface module that provides two 25-GbE (SFP28) ports.
VIM5-4Y versatile interface module that provides four 25-GbE (SFP28) ports.
VIM5-4YE versatile interface module that provides four 25-GbE (SFP28) MACsec capable ports.
VIM5-2Q versatile interface module that provides two 40-GbE (QSFP) ports.
Warning
The switch must be powered off before you install any VIMs options. The interface module options are not hot swappable.
An RJ45 serial console port on the rear panel of the VSP 4900 series switch enables you to connect a terminal and perform local management. An Ethernet management port can be used to connect the system to a out of bound management network for administration. Alternatively, you can use an Ethernet cable to connect this port directly to a laptop to view and locally manage the switch configuration. The Ethernet management port supports 10/100/1000 Mbps speeds.
There is also a USB console port. If the USB console port is connected, it will be selected over the RJ45 console port. The USB console port will disconnect when the switch is rebooted. You can re-connect the port if needed. When the USB console is active, any messages from the switch to the client terminal will be echoed to both the front panel USB console and the rear panel RJ45 serial port; however, no user input will be accepted from the rear panel port.
Each base model is available with front-to-back cooling.
Switch cooling is provided by replaceable fan modules. The available fan module uses airflow from front to back. Two modular power supply slots accommodate AC power supplies. Power supplies have integrated cooling fans that operate independently of the switch fan.
A spare fan module (XN-FAN-002-F) with front-to-back airflow is available for VSP 4900 switches.
Two power supply bays accommodate AC power supplies. Power supplies have integrated cooling fans that operate independently of the switch fans. Like the fan modules, the power supplies are available in models with front-to-back cooling airflow. For more information about the power supplies used in the VSP 4900 switches, see Removing and Replacing Components.
Power supplies are ordered separately.
Caution
Air must flow in the same direction for all installed fan modules and power supplies in a switch.Each Solid-state Drive (SSD) provides modular storage support. VSP 4900 series switches accommodates one SSD module using a reserved slot on the rear of the switch, and is supported on VOSS release 8.1.5 and later.
Warning
The switch must be powered off before you install any interface module options (VIM5s). The interface module options are not hot swappable.
See Solid-state Drives for more information.
All VSP 4900 switch models support an operating range from 0°C to 50°C.
