CHAPTER 1
Product Overview
Cisco Catalyst Micro Series switch is a small form factor micro switch designed to provide networking
solutions for decentralized networking. The Cisco Catalyst Micro Series family of switches is ideal for FTTx
deployments.
The following are some of the features of Cisco Catalyst Micro switches:
•provides four 1 Gigabit Ethernet (G) ports and two 1 G Copper or Fiber uplinks, with line-rate forwarding
performance
• provides power over ethernet plus (PoE+) support with power budget upto 60 W and 120 W for different
switch models
• enables silent operation and enhanced reliability with fan less design
• provides USB-C connector for power sourcing end user devices
• supports flexible mounting options such as wall mount, cable duct mount, desktop and table bottom
mount

Hardware Features
This section describes the different hardware features supported on Cisco Catalyst Micro Series Switches.
PoE and PoE+ Ports
The PoE/PoE+ ports on the switch provide PoE+ support for devices compliant with IEEE 802.3af and IEEE
802.3at and also provide PoE support for end points such as access points, IP camera or surveillance systems,
Cisco IP Phones and so on. The PoE switch ports are Power Source equipment (PSE) capable and source

power to PD devices connected to the downlink ports. The switch can source PoE power of up to 30W per
port, with a total budget that varies depending on the power adapter used. For more information about total
PoE budget, see Power Supply Slot, on page 4.
The PoE ports use RJ-45 connectors with Ethernet pinouts. The end points are connected to the switches using
CAT5/CAT5e/CAT6/CAT6a cables and they are powered and controlled through IP.
Console Ports
The console ports connect the switch to a PC running Microsoft Windows or to a terminal server. Cisco
Catalyst Micro Series switches has a USB 2.0 Type B micro console port (5-pin connector).
To use the USB 2.0 Type B micro console port, an external USB device driver must be installed on any PC
connected to the console port (for operation with Microsoft Windows). Mac OS X or Linux do not require
special drivers. With the USB device driver, you can connect and disconnect the USB cable from the console
port without affecting Windows HyperTerminal operations.
This illustration shows a 5-pin micro-Type B USB port.
Figure 3: USB 2.0 Type B Micro Port
The USB 2.0 Type B micro connector allows a USB Type A port to be connected directly to the switch console
management port using a USB Type A to USB Type B micro cable.
Set the baud rate for the console port to 115200 bits per second using the speed command. For information
on using the CLI to configure the USB console interface, see the Software Configuration Guide.
microSD Flash Memory Card Slot
The switch provides a memory card slot that enables booting the device using a removable microSD flash
memory card. When configured, the switch checks for configuration files and boot images on the microSD
card and prefers booting from microSD memory card to system flash. This enables quick upgrades and
replacement of switches without reconfiguring the new switch.
Power Supply Slot
The switch provides a power supply slot for powering the switch using an external AC-DC adapter. It supports
two power supply adapters of 80 W and 65 W respectively. The default power adapter supported is 65 W.
You must use the power inline ps watt power number CLI to switch between the power supplies. To return
to the default settings use the no form of the command.
You can order an adapter with the switch, or you can order it later from your Cisco representative. The
following are the power adapters supported by Cisco Catalyst Micro Series switches.
• PSU-80W-AC: 80 W AC power adapter
• 65 W AC to DC power adapter with a specification of 53 V/1.22 A

LEDs
You can use the system and port LEDs to monitor switch activity and performance. To conserve power, the
LEDs remain off by default when switch is powered on. Press the Mode button to turn on the LEDs.

Downlink Port Data LEDs
RJ-45 ports have port LEDs. These LEDs, as a group or individually, provide information about the switch
and about the individual ports.
