• 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.

Management

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 conguration. 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.

Cooling

Each base model is available with front-to-back cooling.

Switch cooling is provided by replaceable fan modules. The available fan module uses

airow 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 airow is available for VSP 4900

switches.

Power Supplies

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 airow.

For more information about the power supplies used in the VSP 4900 switches, see

Removing and Replacing Components on page 62.

Power supplies are ordered separately.

Caution

Air must ow in the same direction for all installed fan modules and power

supplies in a switch.
