Product Overview

Power Supply Slots

The chassis has two power supply slots that accept either AC-input or DC-input power supplies, or one of

each. The chassis is delivered with power supplies pre-installed in the power supply slots. If only one power

supply is ordered, then a blank cover is installed in the empty power supply slot, which must remain installed

if a power supply is not installed.

The management port is a 10/100/1000 copper Ethernet port directly connected to the route processor. The

switch also has a fibre port that can be used as the Ethernet Management port. It supports TFTP image

downloading, network management, SNMP, Telnet, and SSH connections. Flexible NetFlow export is not

supported on the management port. The management port is isolated from other ports in the system in a

dedicated management VRF; it is not part of the EARL forwarding logic. The management port provides

direct access to the CPU, even when the system is heavily loaded.

The management port is a Layer 3 port in host mode, and only accepts traffic that terminates on the router.

This port does not route packets between itself and other ports. The port processes only the following packet

types and properly enqueues them:

• Address Resolution Protocol (ARP)

• IPv4 unicast

• IPv6 unicast

• Cisco Discovery Protocol (CDP)

• Link Layer Discovery Protocol (LLDP)
