Fan-Tray Assembly
The fan-tray assembly is preinstalled on the right side of theCisco ME 2600X shelf. The fan-tray assembly
is removable and holds fans and fan-control circuitry for the shelf. The fan-tray assembly should be accessed
only if a fan failure occurs.
The fan-tray assembly has the following ports:
• EOBC (Ethernet Out-of-Band Channel)—An RJ-45 port that supports high bandwidth external
connectivity. If the shelf fails to boot up, the EOBC port also called as the disaster recovery port is used
to log in to the shelf for troubleshooting.
Note
The EOBC port is meant only for TAC (Technical Assistance Center) usage.
• PPS (Pulse Per Second)—A mini BNC output port that provides timing signals to an external equipment
from the shelf.
• 10MH—A mini BNC output port that provides timing signals at a frequency of 10 MHz to an external
equipment from the shelf and RET for power terminals A and B.

OL-28849-02
31
Installing the Cisco ME 2600X Shelf
Fan Speed
• ToD/PPS (Time of Day/Pulse Per Second)—An RJ-45 serial output port that provides time and day
information and timing signals to an external equipment from the shelf.
• CONSOLE—A USB port that is used to connect a console terminal. The console terminal can be one
of the following:
• An ASCII terminal or a PC running terminal emulation software
• A modem
The following figure shows the ports on the fan-tray assembly:
Figure 14: Ports on the Fan-Tray Assembly
Note
The timing signals are compliant with the IEEE 1588 standard.
The console port provides access to the shelf either locally (using a console terminal), or remotely (using a
modem). Console connections transmit at slower speeds than modems; therefore, the console connection is
suited for use with console terminals.
Note
An RJ-45 serial port is used for TOD/PPS functionality. The two RJ-45 pins 7 and 8 is used for TOD
(Time Of Day) functionality and the other two RJ-45 pins 1 and 2 are used for PPS functionality. Even
though an RJ-45 cable is used for TOD/PPS connection, a serial link is established. Two mini coax
connectors with RG316 1.0/2.3 M/M cables (50 ohm) are used for PPS (Pulse Per Second) and for 10MHz
sinusoidal signal. Cable for TOD/PPS and 10MHz shall be shielded.
Note
For rules about provisioning timing references, see Telcordia SR-NWT-002224.
Fan Speed
Fan speed is controlled by the microprocessor present in the Cisco ME 2600X shelf. The sensors measure the
critical component temperature of the Cisco ME 2600X shelf. Multiple fan speed levels are supported.

Measuring DC Voltage on the Cisco ME 2600X shelf
Caution
Do not apply power to the shelf assembly until you complete all the installation steps.
Procedure
Step 1
Using a voltmeter, verify the office battery and ground at the following points on the fuse panel:
a) To verify the power, place the black test lead of the voltmeter to the return (RET). Place the red test lead
on the BAT-A connection and verify that:
For a –48 VDC power supply, the voltage is between –40.5 VDC and –57.6 VDC. Place the red test lead
on the BAT-B connection and verify that it is between –40.5 VDC and –57.6 VDC.
Note
The voltages –40.5 VDC and –57.6 VDC are, respectively, the minimum and maximum voltages
required to power the shelf that has –48V DC power supply. The nominal steady state voltage is
–48 VDC.
b) To verify the ground, place the black test lead of the voltmeter to the frame ground. Place the red test lead
on the BAT-A return ground and verify that no voltage is present, that is, meter reading must be 0 VDC.
Place the red test lead on the BAT-B return ground and verify that no voltage is present, that is, meter
reading must be 0 VDC.
Step 2
To power up the node, insert the fuse into the fuse position according to site practice. For a –48V DC power
supply, the fuse rating must not exceed 10 A.
Step 3
Using a voltmeter, verify the shelf for –48 VDC battery and return:
a) To verify the BAT-A of the shelf, place the black lead of the voltmeter to the return. Place the red test
lead to the –48V (BAT-A battery connection) red cable. Verify that it reads between –40.5 VDC and –57.6
VDC. Then place the red test lead of the voltmeter to the RET1 (BAT-A return ground) black cable and
verify that no voltage is present, that is, meter reading must be 0 VDC.
Note
For a shelf that has –48 VDC power supply, the voltages –40.5 VDC and –57.6 VDC. are,
respectively, the minimum and maximum voltages required to power the shelf. The nominal
steady state voltage is –48 VDC.
b) To verify the BAT-B of the shelf, place the black test lead of the voltmeter to the return. Place the red test
lead to the –48 V (BAT-B battery connection) red cable. Verify that it reads between –40.5 VDC and
–57.6 VDC. Then place the red test lead of the voltmeter to the RET2 (BAT-B return ground) black cable
and verify that no voltage is present, that is, meter reading must be 0 VDC.
c) To verify the ground, place the black test lead of the voltmeter to the frame ground. Place the red test lead
on the BAT-A return ground and verify that no voltage is present, that is, meter reading must be 0 VDC.
Place the red test lead on the BAT-B return ground and verify that no voltage is present, that is, meter
reading must be 0 VDC.

Troubleshooting the Cisco ME 2600X Shelf
This chapter explains how to troubleshoot the Cisco ME 2600X shelf.
• Check Switch Connections, page 71
• Check Switch Performance, page 73
• Environmental Alarms for Cisco ME 2600X, page 74
Check Switch Connections
Review this section when troubleshooting switch connectivity problems.
Bad or Damaged Cable
Always check the cable for marginal damage or failure. A cable might be sufficient to connect at the physical
layer but it could cause packet corruption because of subtle damage to its wiring or connectors. You can
identify this situation by packet errors, or the port constantly loses and regains link. In these situations:
• Check or change the copper or fiber-optic cable with a good working cable.
• Look for broken or missing pins on cable connectors.
• Rule out any insufficient patch panel connections or media convertors between the source and the
destination. If possible, bypass the patch panel or eliminate faulty media convertors, such as
fiber-optic-to-copper convertors.
• Try using the cable in another port or interface to see if the problem exists there.
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 unshielded twisted pair (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 ports on the connected device match and that they use the same type of encoding, optical
frequency, and fiber type.
Cisco ME 2600X Series Ethernet Access Switch Hardware Installation Guide
OL-28849-02
71
Troubleshooting the Cisco ME 2600X Shelf
Check Switch Connections
• For copper connections, determine if a crossover cable was used when a straight-through cable was
required, or the reverse. Enable auto-MDIX on the switch, or replace the cable.
Link Status
Verify that both sides are linked. A single broken wire or one shutdown port can cause one side to show link,
but the other side does not have link.
A link 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 link light for the port does not come on:
• Connect the cable from the switch to a good working device.
• Make sure that both ends of the cable are connected to the correct ports.
• Verify that both devices have power.
• Verify that you are using the correct cable type.
• Check for loose connections. Sometimes a cable appears to be connected, but it might not be. Disconnect
and then reconnect the cable.
SFP Module Port Issues
Use only Cisco small form-factor pluggable (SFP) modules on the switch. Each Cisco module has an internal
serial EEPROM that is encoded with security information. This encoding helps us identify and validate that
the module meets the requirements for the switch. Check these items:
• Bad or wrong SFP module. Exchange the suspect module with a good working module. Verify that this
module supports this platform.
• Use the show interfaces privileged EXEC command to check the port for module error-disabled, disabled,
or shutdown status. Re-enable the port if necessary.
• Make sure that all fiber-optic connections are properly cleaned and securely connected.
Port and Interface Settings
One of the causes for port connectivity failure could be a disabled port. Verify that the port or interface is not
disabled or for some reason powered down. If a port or interface is manually shut down on one or the other
side of the link, the link does not come up until you re-enable the port. Use the show interfaces privileged
EXEC command to check the port for interface error-disabled, disabled, or shutdown status on both sides of
the connection. If necessary, re-enable the port or the interface.
Ping the End Device
Check the end device by pinging it 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
Spanning Tree Protocol (STP) loops can cause serious performance issues that might appear to be port or
interface problems. In this situation, the switch bandwidth is used repeatedly by the same frames, crowding
out legitimate traffic.
Cisco ME 2600X Series Ethernet Access Switch Hardware Installation Guide
72
OL-28849-02
Troubleshooting the Cisco ME 2600X Shelf
Check Switch Performance
A unidirectional link can cause loops. This occurs when the traffic that the switch sends is received by its
neighbor, but the switch does not receive the traffic that is sent from the neighbor. A broken fiber-optic cable
or a port issue could cause this one-way communication.
You can enable the UniDirectional Link Detection (UDLD) protocol on the switch to help identify
difficult-to-find unidirectional link problems. UDLD supports a normal mode of operation (the default) and
an aggressive mode. In normal mode, UDLD detects unidirectional links because of incorrectly connected
interfaces on fiber-optic connections. In aggressive mode, UDLD also detects unidirectional links caused by
one-way traffic on fiber-optic and twisted-pair links and by incorrectly connected interfaces on fiber-optic
links. For information about enabling UDLD on the switch, see the "Understanding UDLD" section in the
software configuration guide.
Check Switch Performance
Review this section when you troubleshoot switch performance problems.
Speed, Duplex, and Autonegotiation
If the port statistics show a large number of alignment errors, frame check sequence (FCS), or late-collisions
errors, a speed or duplex mismatch might be the problem.
A common issue with speed and duplex occurs when the duplex settings are mismatched between two switches,
between a switch and a router, or between the switch and a workstation or server. This can happen when you
manually set the speed and duplex or because of autonegotiation issues between the two devices.
These circumstances can result in a mismatch:
• A manually set speed or duplex parameter is different from the manually set speed or duplex parameter
on the connected port.
• A port is set to autonegotiate, and the connected port is set to full duplex with no autonegotiation.
To maximize switch performance and ensure a link, follow one of these guidelines when you set or change
the settings for duplex and speed:
• 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, configure the duplex settings on the two ports to match. The
speed parameter can adjust itself even if the connected port does not autonegotiate.
Autonegotiation and NIC Cards
Problems sometimes occur between the switch and third-party network interface cards (NICs). By default,
the switch ports and interfaces are set to autonegotiate. It is common for devices such as laptop computers or
other devices to also be 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, the firmware or software on your NIC card might be causing the problem. Upgrade the
NIC card driver to the latest version available from the manufacturer.
