BITS Port
The Building Integrated Timing Supply (BITS) port is an RJ-45 interface that provides external
synchronized clocking through a timing signal generator (TSG). The BITS input is an external timing
reference that must be traceable to a stratum 3 clock or better. The BITS port on the switch can be
configured to accept either a T1 or an E1 framed input. Although this clock input is T1 or E1 framed, it
does not carry data and cannot be used for any other purpose than to derive clocking for the system.
Alarm Input Port
The switch supports four alarm inputs. The alarm input is a dry-contact alarm port. Use the CLI to define
each alarm input to respond to a normally open or closed dry-contact closure and to define the alarm
severity as minor, major, or critical. When a condition triggers an alarm, the console displays an alarm
message, and the corresponding Alarm LED responds (see the “Alarm LEDs Description” section on
page 1-9).

Product Overview

Management and Console Port
You can connect the switch to a host such as a Windows workstation or a terminal server through the
10/100/1000 Ethernet management port or the console port. The 10/100/1000 Ethernet management port
connection uses a standard RJ-45 crossover or straight-through Ethernet cable. The console port
connection uses a RJ-45-to-DB-9 female cable.
The Ethernet management port operates in any combination of 10, 100, or 1000 Mb/s, and its traffic is
isolated from the other ports. See Table 1-7 for descriptions of the Ethernet management port LEDs. See
the “10/100/1000 Ethernet Management Port” section on page B-3 for pinout information.
For console port and adapter pinout information, see the “Console Port Adapter Pinouts” section on
page B-8.
10/100/1000 Gigabit Ethernet Ports
The 10/100/1000 Ethernet ports use standard RJ-45 connectors with Ethernet pinouts. The maximum
cable length is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires Category 5,
Category 5e, or Category 6 unshielded twisted pair (UTP) cable. The 10BASE-T traffic can use
Category 3 or Category 4 UTP cable.
The autonegotiation feature is enabled by default. The switch ports configure themselves to operate at
the speed of attached devices. If the attached device does not support autonegotiation, you can explicitly
set the switch port speed and the duplex parameters. To maximize performance, either let the ports
autonegotiate both speed and duplex, or set the port speed and duplex parameters on both ends of the
connection.
For simplified cabling, the automatic medium-dependent interface crossover (auto-MDIX) feature is
enabled by default. The switch detects the required cable type for copper Ethernet connections and
configures the interface accordingly. You can use either a crossover or a straight-through cable for
connections to a switch 10/100/1000 Ethernet port, regardless of the type of device on the other end of
the connection.
SFP+ and SFP Modules
The switch 10-Gigabit Ethernet SFP+ modules are used for connections to other devices. These
transceiver modules are field-replaceable, providing the uplink interfaces when inserted in an SFP+
module slot. You can use any combination of SFP+ or SFP modules. The SFP+ modules have LC
connectors for fiber-optic connections. The SFP+ module slots support SFP+ and 1000BASE-X SFP
modules. The SFP+ module slots do not support 100BASE-X and 1000BASE-T modules.
Use only Cisco SFP+ or SFP modules on the switch. Each Cisco module has an internal serial EEPROM
that is encoded with security information.

Power Supply Module Features
Power Supply Module Features
The Cisco ME 3800X and ME 3600X switches support two power supply modules, either AC or DC
input. You can install two AC or DC input power supply modules, a mix of AC and DC input power
supply modules, or one power supply and one fan module. The power supply and fan modules are
hot-swappable.
Caution
Both slots must be occupied either by two power supply modules or a power supply and a fan module.
Do not run the switch with an empty slot unless you are replacing a faulty power supply or fan module.
Running the switch with an empty slot triggers an alarm.
Each power supply module contains three fans. The switch can operate safely if one fan fails. A fan
failure triggers an alarm. When a fan fails, replace the power supply module immediately.
See Chapter 3, “Installing and Removing AC and DC Input Power Supply and Fan Modules,” for
instructions on installing the AC and DC input power supply and fan module. See Appendix A,
“Technical Specifications,” for voltage and other specifications.

•
Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent
lighting fixtures. Make sure that the cabling is safely away from other devices that might damage
the cables.
•
Airflow around the switch and through the vents is unrestricted.
Note
•
If the switch is installed in a closed or multirack assembly, the temperature around it might be
greater than normal room temperature.
Before you connect the switch to a power source, note the power consumption specifications in
Appendix A, “Technical Specifications.”
Verifying Switch Operation
Before installing the switch in a rack, on a wall, on a table, or on a shelf, you should power the switch
and verify that the switch passes the power-on self-test (POST).
To power on the switch, see Chapter 3, “Installing and Removing AC and DC Input Power Supply and
Fan Modules.”
When the switch begins POST, the System LED blinks green, and the other LEDs remain green. When
the switch passes POST, the System LED becomes green. The other LEDs turn off and return to their
operating status. If the switch fails POST, the System LED is amber.
Note
Contact Cisco Systems immediately if your switch fails POST.

Connecting to the 10/100/1000 Ports
The switch 10/100/1000 ports configure themselves to operate at the speed of attached devices. If the
attached ports do not support autonegotiation, you can explicitly set the speed and duplex parameters.
Connecting devices that do not autonegotiate or that have their speed and duplex parameters manually
set can reduce performance or result in no linkage.
To maximize performance, choose one of these methods for configuring the Ethernet ports:
•
Let the ports autonegotiate both speed and duplex.
•
Set the port speed and duplex parameters on both ends of the connection.
Follow these steps to connect to 10BASE-T, 100BASE-TX, or 1000-BASE-T devices:
Step 1
Note
Step 2
When connecting to workstations, servers, and routers, connect a straight-through cable to an RJ-45
connector on the front panel. (See Figure 2-15.) When connecting to switches or repeaters, use a
crossover cable. (See the “Cables and Adapters” section on page B-5 for cable-pinout descriptions.)
You can use the mdix auto interface configuration command in the CLI to enable the automatic
medium-dependent interface crossover (auto-MDIX) feature. The switch then detects the required cable
type for copper Ethernet connections and configures the interfaces accordingly. Therefore, you can use
either a crossover or a straight-through cable for connections to a copper 10/100/1000 or 1000BASE-T
SFP module port on the switch, regardless of the type of device on the other end of the connection.
Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on
when both devices have established link. (See Figure 2-15.)

Diagnosing Problems
The LEDs on the front panel provide troubleshooting information about the switch. They show power-on
self-test (POST) failures, port-connectivity problems, and overall switch performance. You can also get
statistics from the CLI or from an SNMP workstation. See the software configuration guide and the
switch command reference on Cisco.com or the documentation that came with your SNMP application
for more information.
Switch POST Results
As the switch powers on, it begins the POST, a series of tests that runs automatically to ensure that the
switch functions properly. It might take several minutes for the switch to complete POST.
When the switch begins POST, the System LED blinks green, and the other LEDs remain green. When
POST succeeds, the System LED becomes green. The other LEDs turn off and return to their operating
status. If the switch fails POST, the System LED is amber.
You can use the show diagnostics post user EXEC command to display the POST results.
Note
POST failures are usually serious. Contact your Cisco technical support representative if your switch
does not pass POST.

Troubleshooting
Diagnosing Problems
Switch LEDs
You must have physical access to the switch to do this. Look at the port LEDs for troubleshooting
information about the switch. See the “LEDs” section on page 1-6 for a description of the LED colors
and their meanings.
Switch Connections
Bad or Damaged Cable
Always examine the cable for marginal damage or failure. A cable might be just good enough to connect
at the physical layer, but it could corrupt packets as a result of subtle damage to the wiring or connectors.
You can identify this situation because the port has many packet errors or the port constantly flaps (loses
and regains link).
•
Examine or exchange the copper or fiber-optic cable with a known, good cable.
•
Look for broken or missing pins on cable connectors.
•
Rule out any bad patch panel connections or media convertors between the source and the
destination. If possible, bypass the patch panel, or eliminate faulty media convertors
(fiber-optic-to-copper).
•
Try the cable in another port or interface, if possible, to see if the problem follows the cable.
Ethernet and Fiber Cables
Make sure that you have the correct cable type for the connection:
•
For Ethernet, use Category 3 copper cable for 10 Mb/s UTP connections. Use either Category 5,
Category 5e, or Category 6 UTP for 10/100 or 10/100/1000 Mb/s connections.
•
For fiber-optic connectors, verify that you have the correct cable for the distance and port type. Make
sure that the connected device ports both match and use the same type encoding, optical frequency,
and fiber type.
•
For copper connections, determine if a crossover cable was used when a straight-through was
required or the reverse. Enable auto-MDIX on the switch, or replace the cable.
Link Status
Verify that both sides have link. A single broken wire or one shutdown port can cause one side to show
link, but the other side does not have link.
A port LED does not guarantee that the cable is fully functional. The cable might have encountered
physical stress that causes it to function at a marginal level. If the port LED does not turn on:
•
Connect the cable from the switch to a known good device.
•
Make sure that both ends of the cable are connected to the correct ports.
•
Verify that both devices have power.

Look for loose connections. Sometimes a cable appears to be seated, but is not. Disconnect the cable
and then reconnect it.
SFP+ and SFP Module Port Issues
Use only Cisco SFP+ and SFP modules on the switch. Each Cisco module has an internal serial
EEPROM that is encoded with security information. This encoding provides a way for Cisco to identify
and validate that the module meets the requirements for the switch. Check these items:
•
Bad or wrong SFP+ and SFP module. Exchange the suspect module with known good module.
Verify that the module is supported on this platform. (The switch release notes on Cisco.com list the
SFP+ and SFP modules that the switch supports.)
•
Use the show interfaces privileged EXEC command to see if the port or module is error-disabled,
disabled, or shutdown. Re-enable the port if needed.
•
Make sure that all fiber connections are properly cleaned and securely connected.
Port and Interface Settings
An obvious but sometimes overlooked cause of port connectivity failure is a disabled interface. Verify
that the interface is not disabled or powered off for some reason. If an interface is manually shut down
on one side of the link or the other side, the link does not come up until you re-enable the interface. Use
the show interfaces privileged EXEC command to see if the interface is error-disabled, disabled, or
shutdown on either side of the connection. If needed, re-enable the interface.
Ping the End Device
Ping from the directly connected switch first, and then work your way back port by port, interface by
interface, trunk by trunk, until you find the source of the connectivity issue. Make sure that each switch
can identify the end device MAC address in its Content-Addressable Memory (CAM) table.
Spanning Tree Loops
STP loops can cause serious performance issues that look like port or interface problems.
Unidirectional links can cause spanning-tree loops. A unidirectional link occurs when the traffic sent by
the switch is received by its neighbor, but does not receive traffic sent by the neighbor. A broken
fiber-optic cable, other cabling, or a port issue could cause this one-way communication.
The UniDirectional Link Detection (UDLD) protocol helps identify unidirectional link problems. For
more information, see the “Understanding UDLD” section in the switch software configuration guide on
Cisco.com.

Troubleshooting
Clearing the Switch IP Address and Configuration
Switch Performance
Speed, Duplex, and Autonegotiation
If the port statistics show a large amount of alignment errors, frame check sequence (FCS), or
late-collisions errors, this might mean a speed or duplex mismatch.
A common issue with speed and duplex is when the duplex settings are mismatched between two
switches, between a switch and a router, or between the switch and a workstation or server. Mismatches
can happen when manually setting the speed and duplex or from autonegotiation issues between the two
devices.
To maximize switch performance and to ensure a link, follow one of these guidelines when changing the
duplex or speed settings.
•
Let both ports autonegotiate both speed and duplex.
•
Manually set the speed and duplex parameters for the ports on both ends of the connection.
•
If a remote device does not autonegotiate, set the same duplex settings on the two ports. The speed
parameter adjusts itself even if the connected port does not autonegotiate.
Autonegotiation and NICs
Problems sometimes occur between the switch and third-party network interface cards (NICs). By
default, the switch ports and interfaces are set to autonegotiate. Devices like laptops or other devices are
commonly set to autonegotiate, yet sometimes autonegotation issues occur.
To troubleshoot autonegotiation problems, try manually setting both sides of the connection. If this does
not solve the problem, there could be a problem with the firmware or software on your NIC. You can
resolve this by upgrading the NIC driver to the latest available version.
Cabling Distance
If the port statistics show excessive FCS, late-collision, or alignment errors, verify that the cable distance
from the switch to the connected device meets the recommended guidelines. See the “Cables and
Adapters” section on page B-5 for cabling guidelines.
Clearing the Switch IP Address and Configuration
This section describes how to reset the switch by rerunning the initial configuration dialog (system
configuration dialog). These are reasons why you might want to reset the switch:
Caution
•
You installed the switch in your network and cannot connect to it because you assigned the wrong
IP address.
•
You want to clear all the configuration settings from the switch and assign a new IP address.
This procedure clears the IP address and all configuration information stored on the switch. Do not
follow this procedure unless you want to completely reconfigure the switch.

Troubleshooting
Finding the Switch Serial Number
To reset the switch:
1.
At the switch prompt, enter enable, and press Return or Enter.
2.
At the privileged EXEC prompt, switch#, enter setup, and press Return or Enter.
The switch displays the prompt to run the initial configuration dialog. The switch now behaves like an
unconfigured switch. You can configure the switch by using the CLI setup procedure described in
Appendix C, “Configuring the Switch with the CLI-Based Setup Program.”
Finding the Switch Serial Number
If you contact Cisco Technical Assistance, you need to know the serial number of your switch. Use these
figures to locate the serial number location. You can also use the show version privileged EXEC
command or the show inventory user EXEC command to get the serial number.

1. Modal bandwidth applies only to multimode fiber.
2. A mode-field diameter/cladding diameter = 9 micrometers/125 micrometers.
3. Requires a mode-conditioning patch cord. An ordinary patch cord with MMF, 1000BASE-LX/LH SFP modules, and a short link distance can cause
transceiver saturation, resulting in an elevated bit error rate (BER). When using the LX/LH SFP module with 62.5-micron diameter MMF, you must also
install a mode-conditioning patch cord between the SFP module and the MMF cable on both the sending and receiving ends of the link. Link distances
greater than 984 feet (300 m) require the mode-conditioning patch cord.
4. 1000BASE-ZX SFP modules can send data up to 62 miles (100 km) by using dispersion-shifted SMF or low-attenuation SMF; the distance depends on
the fiber quality, the number of splices, and the connectors.
Note
When the fiber-optic cable span is less than 15.43 miles (25 km), you should insert a 5-decibel (dB) or
10-dB inline optical attenuator between the fiber-optic cable plant and the receiving port on the
1000BASE-ZX SFP module at each end of the link.

To identify a crossover cable, compare the two modular ends of the cable. Hold the cable ends
side-by-side, with the tab at the back. The wire connected to pin 1 on the left plug should be the same
color as the wire connected to pin 3 on the right plug. The wire connected to pin 2 on the left plug should
be the same color as the wire connected to pin 6 on the right plug.

Console Port Adapter Pinouts
The console port uses an 8-pin RJ-45 connector, which is described in Table B-3 and Table B-4. If you
did not order a console cable with your switch, you need to provide an RJ-45-to-DB-9 adapter cable to
connect the console port of the switch to a console PC. You need to provide an RJ-45-to-DB-25 female
DTE adapter if you want to connect the switch console port to a terminal. You can order a kit (part
number ACS-DSBUASYN=) containing that adapter from Cisco. For console port and adapter pinout
information, see Table B-3 and Table B-4.

Configuring the Switch with the CLI-Based
Setup Program
This appendix provides a CLI-based setup procedure for a standalone switch. Before connecting the
switch to a power source, review the safety warnings in Chapter 2, “Switch Installation” and Chapter 3,
“Installing and Removing AC and DC Input Power Supply and Fan Modules.”
Accessing the CLI Through the Console Port
You can access the CLI on a configured or unconfigured switch by connecting the console port of the
switch to the serial port on your PC or workstation and accessing the switch through a Telnet session.
Starting the Terminal-Emulation Software
Before you power on the switch, start the terminal emulation session so that you can see the output
display from the power-on self-test (POST).
The terminal-emulation software—frequently a PC application such as Hyperterminal or
ProcommPlus—makes communication between the switch and your PC or terminal possible.
Follow these steps to start a terminal-emulation session:
Step 1
Start the terminal-emulation program if you are using a PC or terminal.
Step 2
Configure the baud rate and character format of the PC or terminal to match these console port default
characteristics:
•
9600 baud or 115200 baud (suggested rate)
•
8 data bits
•
1 stop bit
•
No parity
•
None (flow control)

Appendix C
Configuring the Switch with the CLI-Based Setup Program
Entering the Initial Configuration Information
To power on the switch, connect one end of the AC power cord to the AC power connector on the switch,
and connect the other end of the power cord to an AC power outlet.
To power on a DC switch, see Chapter 3, “Installing and Removing AC and DC Input Power Supply and
Fan Modules.”
Entering the Initial Configuration Information
To set up the switch, you need to complete the setup program, which runs automatically after the switch
is powered up. You must assign an IP address and other configuration information necessary for the
switch to communicate with the local routers and the Internet.
IP Settings
You will need this information from your network administrator before you complete the setup program:
•
Switch IP address
•
Subnet mask (IP netmask)
•
Default gateway (router)
•
Enable secret password
•
Enable password
•
Telnet password
Completing the Setup Program
Follow these steps to complete the setup program and to create an initial configuration for the switch:
Step 1
Enter Yes at these two prompts.
Would you like to enter the initial configuration dialog? [yes/no]: yes
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
Basic management setup configures only enough connectivity
for management of the system, extended setup will ask you
to configure each interface on the system.
Would you like to enter basic management setup? [yes/no]: yes
Step 2
Enter a host name for the switch, and press Return.
On a command switch, the host name is limited to 28 characters; on a member switch to 31 characters.
Do not use -n, where n is a number, as the last character in a host name for any switch.
Enter host name [Switch]: host_name
