Catalyst 4500 Series Switches

The Catalyst 4500 series switches consist of the Catalyst 4503 switch, the Catalyst 4506 switch, the Catalyst 4507R switch, and the Catalyst 4510R switch. The switches are designed for high-performance, high-density wiring closet applications. A detailed overview of these switches is in the Catalyst 4500 Series

Installation Guide.

Supervisor Engines

These sections describe the supervisor engines available for the Catalyst 4500 series switches:

• Supervisor Engine I (WS-X4012), which is used in the Catalyst 4003 switch

(Figure 1-1)

• Supervisor Engine II (WS-X4013, which is used in the Catalyst 4006, 4503,

and 4506 switches (Figure 1-2)

• Supervisor Engine II-Plus (WS-X4013+), which is used in the Catalyst 4006,

4503, 4506, and 4507R switches (Figure 1-3)

• Supervisor Engine II-Plus TS (WS-X4013+TS), which is used in Catalyst

4503 switches only (Figure 1-4)

• Supervisor Engine II-Plus 10GE (WS-X4013+10GE), which is used in

Catalyst 4503, 4506, and 4507R switches (Figure 1-5)

• Supervisor Engine III (WS-X4014), which is used in the Catalyst 4006, 4503,

and 4506 switches (Figure 1-6)

• Supervisor Engine IV (WS-X4515), which is used in the Catalyst 4006, 4503,

4506, and 4507R switches (Figure 1-7 )

• Supervisor Engine V (WS-X4516), which is used in the Catalyst 4006, 4503,

4506, 4507R, and 4510R switches (Figure 1-8)

• Supervisor Engine V-10GE (WS-X4516-10GE), which is used in the

Catalyst 4503, 4506, 4507R, and 4510R switches (Figure 1-9)

On the Catalyst 4006, 4503, and 4506 switches, you can install the Supervisor Engine in slot 1 only. On the Catalyst 4507R or 4510R switch, you install the primary supervisor engine in slot 1, and you can install an optional redundant supervisor engine in slot 2.

Supervisor Engines

The supervisor engines have the following features:

• Data path and control for all network interfaces

• Management functions:

–

Interface monitoring

–

Environmental status

–

SNMP and console/Telnet interface

• Hot-swapping

Note Packets are not forwarded while the module is removed. A system

reboot occurs when a supervisor engine is reinserted.

• The Supervisor Engine II-Plus TS provides 12 nonblocking

10/100/1000BASE-T (RJ-45) ports and 8 1000BASE-X (SFP) ports.

• The Supervisor Engine II-Plus 10GE and Supervisor Engine V-10GE provide

2 nonblocking 10GBASE uplink ports.

• The Supervisor Engine II-Plus 10GE and Supervisor Engine V-10GE provide

4 1000BASE-X (SFP) ports.

• The Supervisor Engine IV and V support the Catalyst 4500 series NetFlow

Services Card (WS-F4531). NetFlow is integral to the Supervisor Engine V-1 0 G E.

To install a supervisor engine, follow the procedure in the “Installing the

Modules” section on page 3-2.

The supervisor engines used in Catalyst 4000 and Catalyst 4500 switches are shown in Figure 1-1 to Figure 1-8.

Front-Panel Components

The following connectors, LEDs, and buttons are located on the front panel of the supervisor engine:

• The STATUS LED, which indicates the operating state of the module

• Two Gigabit uplink ports (WS-X4013, WS-X4013+, WS-X4014, and

WS-X4515 supervisor engines only)

• Four SFP Gigabit uplinks ports and 2 10-Gigabit uplink ports on

WS-X4013+10GE and WS-X4016-10GE.

• Eight unmarked switch load indicator LEDs, which provide an approximation

of the current traffic across the backplane

• A console port (DB-25 for the WS-X4012; RJ-45 for the WS-X4013,

WS-X4013+, WS-X4013+ TS, WS-X4013+10GE, WS-X4014, WS-X4515, WS-X4516, and WS-X4516-10GE supervisor engines)

• An Ethernet management port (RJ-45)

• A link status LED, which provides status for the management port

(10BASE-T on the WS-X4012 and 10/100BASE-T on the WS-X4013, WS-X4013+, WS-X4013+ TS, WS-X4013+10GE, WS-X4014, WS-X4515, WS-X4516, and WS-X4516-10GE supervisor engines)

indicates the current traffic load over the backplane (as an approximate percentage).

LINK Indicates the status of the 10/100BASE-T

Ethernet management port or uplink ports.

Green The link is operational.

Orange The link is disabled by user.

Flashing orange The power-on self-test indicates a faulty

port.

Ethernet Management Port

The WS-X4012 supervisor engine has a 10BASE-T Ethernet management port. The WS-X4516-10GE and WS-X4013+10GE supervisor engine modules have a 10/100/1000BASE-T Ethernet management port.The other supervisor engine modules have a 10/100BASE-T Ethernet management port. Supervisor engines use an RJ-45 connector on the front panel with a link status LED. For the location of the port, see Figure 1-1 (WS-X4012), Figure 1-2 (WS-X4013), Figure 1-3 (WS-X4013+), Figure 1-4 (WS-X4013+TS), Figure 1-5 (WS-X4013+10GE),

Figure 1-6 (WS-X4014), Figure 1-7 (WS-X4515), Figure 1-8 (WS-X4516), or Figure 1-9 (WS-X4516-10GE).

TCP/IP-based management services available through inband access also are provided through this port (Telnet and SNMP). This management port also supports image download.

Note The 10BASE-T and 10/100BASE-T Ethernet management ports are for network

management only. These ports do not support network switching.

Console Port

The console port allows you to perform the following functions:

• Configure the switch from the CLI

• Monitor network statistics and errors

• Configure SNMP agent parameters

• Download software updates to the switch or distribute software images

residing in Flash memory to attached devices

The Catalyst 4003 console port is a DCE DB-25 receptacle, which supports a DCE EIA/TIA-232 interface. The console port is an RJ-45 receptacle on the Catalyst 4006, 4503, 4506, and 4507.

Note EIA/TIA-232 was known as recommended standard RS-232 before its acceptance

as a standard by the Electronic Industries Association (EIA) and Telecommunications Industry Association (TIA).

Chapter 1 Module Overview and Specifications

Hot-Swapping Feature

Catalyst 4500 series switches allow you to remove and replace switching modules without powering down the switch. This feature is known as hot swapping.

When you remove or insert a switching module while the switch is operating, the system does the following:

1. Scans the backplane for configuration changes.

2. Initializes all newly inserted switching modules, notes any removed modules,

and places them in the administratively shutdown state.

3. Places any previously configured interfaces on the switching module back to

the state they were in when they were removed. Any newly inserted interfaces are put in the administratively shutdown state, as if they were present (but unconfigured) at boot time. If you insert a similar switching-module type into a slot, its ports are configured and brought online up to the port count of the original switching module.

The system runs diagnostic tests on any new interfaces. If the test passes, the system is operating normally. If the new switching module is faulty, the system resumes normal operation but places the new module in the “faulty” state.

If the diagnostic test fails, the system crashes, which usually indicates that the new switching module has a problem and should be removed.

Port Status

2

Indicates individual port status.

Green The port is operational (a signal is detected).

Orange The link has been disabled by software.

Flashing orange

The link has been disabled due to a hardware failure.

Off No signal is detected.

Caution To avoid erroneous failure messages, allow at least 15 seconds for the system to

reinitialize, and note the current configuration of all interfaces before you remove or insert another switching module.

When you hot swap switching modules, the system displays status messages on the console screen. The following sample display shows the messages logged by the system when a switching module is removed from slot 2:

Console> (enable) 2001 Sep 09 12:23:26 %SYS-5-MOD_REMOVE:Module 3 has been removed Console> (enable) 2001 Sep 09 12:23:44 %SYS-5-MOD_INSERT:Module 3 has been inserted Console> (enable) 2001 Sep 09 12:23:47 %SYS-5-MOD_OK:Module 3 is online Console> (enable)

If you use the show port command to query the module before reinstalling a module to replace the removed one, the system responds, “Module 3 is not installed.” When the module is reinserted, the system recognizes the module as ready again.
