The following information is for FCC compliance of Class A devices: This equipment has been teste d and found to com ply wi th the lim its f or a Class A digital device, p ursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operate d in a commer cial
environment. This equipment generates, uses, and can radi ate radio- frequency energy a nd, if not ins talled and used in acco rdance with th e instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required
to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not
installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to
comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable
protection against such interference in a residential inst allatio n. However , there is no guarantee t hat inter ference wil l not oc cur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital
devices. In that event, your right to use the equipment may be li mited by F CC regula tions, and y ou may be re quired to co rrect any interference to radio or television
communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipm ent or one o f its
peripheral devices. If the equipment causes interference to radio or televisio n receptio n, try to co rrect the in terferen ce by using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio .
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits
controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

LINK A link status LED is located below the 10-GB uplink ports.
1.If either LED is green a nd the ot her is OFF the power supp ly is probabl y not plugge d in. If it is r ed, the
supply is either plugged in and not switched on or it is faulty. It may be necessary to inte rrogate the syst em
for further status using the CLI.
Chassis Cooling
The hot-swappable chassis fan tray (WS-X4992) provides cooling air for the internal ch assis
components. The fans draw air in from the right side of the chassis and exhaust the heated air through
perforations on the right side of the chassis.
Caution When the fan tray is removed, internal circuitry is exposed that should not be touched by tools or fingers.
The system should not operate without a fan tray for longe r than i s necessar y to repl ace a fau lty fan tray
with a new fan tray.
Figure 1-4 shows the direction of airflow through the switch.

Figure 1-4 Catalyst 4900M Chassis Airflow
There are five fans in the fan tray. If an individual fan fails, the other fans continue to run. Sensors
monitor the internal air temperatures. The number of fans in operation and their speed varies according
to the internal temperature for the quietest operation possible. If the air temperature exceeds a desired
threshold, the environmental monitor displays warning messages.
Note Individual fans in the fan tray cannot be replaced; the entire fan tray must be replaced.
Power Supplies
Note For complete power specifications for the Catalyst 4900M switch, see Appendix A, “Specifications.”
The Catalyst 4900M switch has two redundant internal 1000 W AC-input or 1000 W DC- input power
supplies.
The internal power supplies have individual power cords and status LEDs (PS1 and PS2 on the front
panel). There are also LEDs on the power supplies that show status for the input (Input OK) and output
(Output OK) currents. A power cord is used to connect the power supplies to the site AC source. There
is a power switch on the AC-input power supplies; AC power is present when a power cord is plugged
into a power supply and the switch is set to the On position. DC-input power supplies attach to source
DC using customer-supplied cables.
The switch starts with only one power supply plug ged in, bu t redu ndant failove r and load sha ring is not
available in this configuration. Cisco recommends that you always connect both power supplies to
separate AC or DC circuits for optimal power reliability.

Catalyst 4900M Switch Chassis

Catalyst 4900M Half-Card Modules
For safety reasons, the AC power supply must be s witched off and unplugged before it is remove d from
a chassis or inserted into a chassis. DC supplies should have power shut off from the source before they
are removed.
If only one power supply is used, you must use the supplied blank faceplate to cover the empty power
bay. The blank power supply cover maintains EMI shielding and proper air flow through the chassis.
Environmental Monitoring of the Power Supplies
Using the environmental monitoring and reporting functions, you can maintain normal system operation
by resolving adverse environmental conditions prior to loss of operation.
Each power supply monitors its own temperature and output voltages. The C atalyst 4900M swit ch senses
the operating condition of the power supply and reports status through software.
Power Management for the Cataly st 4900M Switch
You can select either AC-input or DC-input power supplies f or your switc h. The Catalyst 4900M switch
supports the following power supplies:
• 1 000 W AC-input
• 1 000 W DC-input
A redundant power supply can be identified and diagnosed by a running system regardless of its input
status. The AC-input and DC-input supplies are interchangeable.
Power Management Modes
The Catalyst 4900M switch supports the redundant power management mode. In this mode, if both
power supplies are operating normally, each provides from 20/80 to 45/55 percent of the total system
power requirements at all times. If one power supply fails, the other unit increases power to 100 percent
of the total power requirement.
Catalyst 4900M Half-Card Modules
The Catalyst 4900M switch chassis has two half-card slots available allowing two half-card modules to
be installed. The following half-card modules are available:
• WS -X4920-GB-RJ45 Hal f-Card Ethernet Mod ule, page 1-9
• WS -X4904-10GE Half-C ard Ethernet Module, pa ge 1-10
• WS -X4908-10GE Half-C ard Ethernet Module, pa ge 1-11
• WS -X4908-10G -RJ45 Half -Card E thernet Module, page 1-13
The half-card modules can be mixed in a chassis.

The WS-X4908-10GE module (Figure 1-7) is an 8-port 10-Gigabit Ethernet module that has the ability
to operate as a 16 port 1-Gigabit module by installing a Cisco TwinGig converter module in the X2
transceiver socket and then installing two 1-Gigabit SFP transceivers in the TwinGig converter.

Note When using TwinGig converters and X2 transceivers on this m odule, keep them grouped i n pairs as
