I hate to say always or never to a question like this. But, in general,
you can use an optical module (such as the 2-port OC-12c ATM SI+) in
any slot. But, for each particular particular module you should always
check the documentation as to what slots are supported. Especially when
using the 6513.
There is a 32 Gbps connection to the shared bus in a 6500, but a 40 Gbps
connection to the switch fabric (20Gbps per channel). Doing some
math... 720/40 equals 18. So, you can have 18 20Gbps channels per
Sup720. On the current 6513, slots 1-8 only have a single channel.
Where, 9-13 have a dual channel. So, 1 channel per the first 8 slots is
8 channels, 2 channels for the last 5 slots is 10 channels, for a
combined 18 channels. All current E chassis's (6503-E, 6504-E, 6506-E,
6509-E have dual channels on all slots).

Hi Mike,
Regarding 6500... Do you know if we can install an optical card on any
module? Or it is restrict on Slot 1?
Thanks,
Gabriel

Up until recently, you could even run 7600 code on a 6500, so
this has
caused a lot of confusion over time.

As a very broad generalization, the 6500 is geared towards
Converged
Enterprise LAN+WAN customers. The 7600 is typically seen more
in
service provider environments or as WAN edge for large
enterprises.
Yes, I know, it's a generalization.
More information about 7600/6500 codes 12.2S:
- IOS 12.2SR is not supported on 6500s, and future 6500 IOS
versions will not be supported on 7600s.
- 7600 chassis is not equivalent to the enhanced 6500 chassis
(7600 is
architecturally similar to the non-E 6500 chassis)
- Currently no hardware differences between 6500 and 7600,
depending
upon IOS version. For example, OSMs are not support in the new
IOS with
Software Modularity.
- Next 6500 IOS releases will have a lot of CatOS parity
features
(especially 802.1X extensions) that will not be on the 7600.
- Software feature differences between 12.2SRA and the 12.2SX on
the
6500.
12.2(33)SRA delivers the following functionality - ranging
from Carrier Ethernet to Mobile to the Enterprise WAN.
- Carrier Ethernet: Ethernet OAM (802.1ag, 802.3ah), Multipoint
Bridging with Locally Significant VLANs, Muxed L2+L3 UNI, H-VPLS
on
SIP-400
- IP / MPLS Routing: Prefix-Independent MPLS TE+FRR,
Class-based &
AToM Tunnel Selection, BGP Next Hop Tracking, BFD for eBGP
- High Availability: Layer 3 MPLS NSF/SSO, OSPF Graceful
Restart
(RFC 3623)
- Hardware: FE SPAs, OC-48/STM-16 POS SPAs, CHSTM-1/CHOC3 SPAs
- Network Management: Config Rollback, IP SLA, PWE3 MIB
www.cisco.com/go/fn is probably the best way to look for
detailed
feature differences.

Hi Guys
just a quick question, what are the technicval difference
between a
cisco 7600 router and cisco 6500 switch. to my understanding
they seem
the same, lots of modules are nterchangeable so far i cannot
find a
module that is not interchangeable.
your inouts will be appreaciated.
TIA
