Cisco Enhanced EtherSwitch Services Modules

Cisco enhanced EtherSwitch service modules are complete switching platforms with increased switch to switch traffic load capacity, with Power over Ethernet (PoE) capability, and capable of supporting the following features:

•Dynamic addition and removal of individual Cisco enhanced EtherSwitch service modules

•Integrated management through all management interfaces (command-line interface [CLI], Simple Network Management Protocol [SNMP], and HTTP)

•Features such as UplinkFast, EtherChannel, and equal-cost routing across the switch that provide redundancy and reduce network disruption from individual component failure

•GE HIMI backplane connection (using the connect (module) command) provides interface support, which allows the Cisco enhanced EtherSwitch service module to route ingress or egress packets directly to or from the Cisco enhanced EtherSwitch service module from or to other GE enabled modules without going through the router CPU.

For information about these and other features available in Cisco enhanced EtherSwitch service modules, see the Cisco Enhanced EtherSwitch Service Modules Configuration Guide at the following URL:

Cisco Enhanced EtherSwitch Service Module Overview

The Cisco enhanced EtherSwitch service modules are switch modules to which you can connect Cisco IP phones, Cisco wireless access point workstations, and other network devices such as servers, routers, switches, and other network switch modules.

---

Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the enhanced EtherSwitch service modules (SM-ES2-16-P, SM-ES3-16-P, SM-ES3G-16-P, SM-ES2-24-P, SM-ES3-24-P, and SM-ES3G-24-P) only to intra-building or unexposed wiring or cable. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring. The intrabuilding cable must be shielded and the shield must be grounded at both ends.

Cisco Enhanced EtherSwitch Service Module Ports

The following sections describes the port types and port numbering on the service modules:

•Cisco Enhanced EtherSwitch Service Module LEDs

•Port Types

Port Numbering

The Ethernet ports are numbered right to left, top to bottom. The port numbering scheme to configure the ports on the Cisco enhanced EtherSwitch service module includes the port type (such as fa or fastethernet for Fast Ethernet, or gi or gigabitethernet for Gigabit Ethernet), the module slot number (always 0), and the switch port number.

For example, to configure the Gigabit Ethernet port 3 in slot 0, the interface configuration command would be:

switch (config)# interface gi 0/3

Port Types

All Cisco enhanced EtherSwitch service modules, use RJ-45 connectors to provide Fast Ethernet (FE) or Gigabit Ethernet (GE) connections.

---

Note 10/100/1000 Ethernet interfaces can support trunks.

---

---

Note Cisco enhanced EtherSwitch service modules do not have a physical console interface, but are accessible for software configuration and other operational procedures through console sessions between the Cisco enhanced EtherSwitch service module and the host router.

---

10/100 and 10/100/1000 Ports

You can set the 10/100 ports on the Cisco enhanced EtherSwitch service module to operate in any combination of half duplex, full duplex, 10 Mbps, or 100 Mbps. You can set the 10/100/1000 ports to operate at 10 Mbps, 100 Mbps, or 1000 Mbps in full duplex. You can also set these ports for speed and duplex autonegotiation in compliance with IEEE 802.3ab. (The default setting is autonegotiate.)

When set for autonegotiation, the port senses the speed and duplex settings of the attached device and advertises its own capabilities. If the connected device also supports autonegotiation, the Cisco enhanced EtherSwitch service module port negotiates the best connection (that is, the fastest line speed that both devices support and full-duplex transmission if the attached device supports it) and configures itself accordingly. In all cases, the attached device must be within 100 meters (328 feet).

Except for SM-ES2-24 modules, all 10/100 ports on the Cisco enhanced EtherSwitch service modules can provide power to IEEE 802.3af-compliant and noncompliant PoE devices. PoE devices are Cisco IP phones, Cisco access points, and some Cisco switches. PoE, formerly referred to as inline power, is available in all network module form factors supported by Cisco modular access routers.

Table 2 provides information on Cisco enhanced EtherSwitch service module port speed and duplex information.

Table 2 Port Speed and Duplex

Port Function	Explanation
Speed	The operating speed of the switch port. You can choose Auto (autonegotiation) if the connected device can negotiate the link speed with the switch port. The default settings are: •Auto for the external 10/100-Mbps Fast Ethernet ports •Auto for the external Gigabit Ethernet RJ-45 (10/100/1000-Mbps) ports •
Duplex	The duplex mode of the switch port. Choose from one of the following: •Auto (autonegotiation) if the connected device can negotiate with the switch •Full (full duplex) if both devices can send data at the same time •Half (half duplex) if one or both devices cannot send data at the same time The default settings are: •Auto for the external 10/100-Mbps Fast Ethernet ports •Auto for the external Gigabit Ethernet RJ-45 (10/100/1000-Mbps) ports Note You cannot set the port to half duplex if the port speed is set to Auto.

Cisco Enhanced EtherSwitch Service Module LEDs

Cisco enhanced EtherSwitch service module LEDs provide green, amber, and off states for system and port status. The following sections describe LEDs on the service modules:

•EN LED

•Port LEDs

---

Note Port LEDs on nonstacking Cisco enhanced EtherSwitch service modules only show link status.

---

EN LED

All Cisco enhanced EtherSwitch service modules have an enable (EN) LED. This LED indicates that the module has passed its self-test and is available to the router. (See Figure 8.) Table 3 lists the EN LED colors and their meanings.

Figure 8 EN LED

Table 3 EN LED 

State	System Status
Off	The Cisco enhanced EtherSwitch service module is not yet operational.
Green	The Cisco enhanced EtherSwitch service module is operational.
Amber	An error has occurred.

Port LEDs

Each port has a port LED. These port LEDs, as a group or individually, display information about the module and about the individual ports.

Table 4 explains how to interpret the port LED colors for link status on the Cisco enhanced EtherSwitch service modules.

Table 4 Port LED on the Cisco Enhanced EtherSwitch Service Modules 

Port LED Color	Description
Off	No link, or the port was administratively shut down. On PoE ports, no inline powered device (PD) detected, or the port is not connected.
Green	A link is present. The port or system is functioning normally. On PoE ports, the Cisco enhanced EtherSwitch service module is providing power to a PD.
Flashing green	Activity is occurring. The port is transmitting or receiving data. Module POST is in progress.
Alternating green-amber	Link fault. On PoE ports, the Cisco enhanced EtherSwitch service module is denying power to a PD, or is experiencing a power delivery fault.
Amber	The port is blocked by the Spanning-Tree Protocol (STP) and is not forwarding data. Note After a port is reconfigured, the port LED can remain amber for up to 30 seconds. On a PoE port, indicates that the port is denied power and that the port is administratively disabled. The system is receiving power but is not functioning properly.
Flashing amber	The port is blocked by STP and is transmitting or receiving packets. On a PoE port, indicates an inline power delivery fault.

Power Considerations

This section describes the power considerations for the router and Cisco enhanced EtherSwitch service modules:

•Power Considerations for the Router

•Power Considerations for the Service Module

---

Warning Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection methods, unless the exposed metal parts are located within a restricted access location and users and service people who are authorized within the restricted access location are made aware of the hazard. A restricted access area can be accessed only through the use of a special tool, lock and key or other means of security. Statement 1072

---

Power Considerations for the Router

Cisco 2900 series and Cisco 3900 series routers supply -48 V power internally (with AC-PoE power supplies) to the Cisco enhanced EtherSwitch service modules.

Power Considerations for the Service Module

The Cisco enhanced EtherSwitch service module supports inline powering of IP phones with -48 V power. This allows IP phones to be plugged into a standard RJ-45 jack and be powered from the switch rather than from an AC wall outlet.

The Cisco enhanced EtherSwitch service module distributes the -48 V power to each of the Ethernet ports that are configured for PoE. Each port can be independently configured for PoE.

Connecting to the Enhanced EtherSwitch Service Module Ports

Both FE and GE ports are used to connect PCs or workstations to the network.

A 10/100/1000 Gigabit Ethernet (GE) port can be used as an uplink port to connect to another router or a server, or can trunk to another Cisco enhanced EtherSwitch service module or switch located in the same chassis or in a separate installation.

Connecting a FE or GE port to the network requires a Category 5 cable with RJ-45 male connectors, not provided with the switch module. Category 5 cables are widely available.
