Release Notes for Cisco IOS Release 12.0(10)W5(18c) Feature Packs for the Cisco Catalyst 8500 CSR
78-10598-02
Catalyst 8540 CSR Route Processor and Switch Module Redundancy
If you have already assigned port channel IDs 57 to 64, you must reassign them before installing an
8-port Gigabit Ethernet line module.
If your switch router does not have an 8-port Gigabit Ethernet line module, you can assign port channel
ID numbers up to 64.
Restrictions on the Online Insertion and Removal of Modules
The following restrictions apply to the online insertion and removal (OIR), also known as hot swapping,
of line modules on the Catalyst 8500 CSR:
• Wait at least one minute after removing a line module before inserting a new one.
• Do not remove more than one line module at a time while the device is operational.
FPGA Upgrade Restriction
On an 8540 CSR, the reprogram command for upgrading the FPGA on the switch processor requires
power cycling the box after completing the FPGA download.
1000BaseZX GBIC Restriction
The Catalyst 8510 and 8540 CSR systems support extra long haul (1000BaseZX) GBICs as follows:
• Catalyst 8540 CSR: A maximum of 12 1000BaseZX GBICs per system to comply with FCC Class
A emissions (CFR 47 Part 15), or 8 1000BaseZX GBICs per system to comply with EN55022 Class
B emissions (CISPR22 Class B).
• Catalyst 8510 CSR: Up to four 1000BaseZX GBICs in a total of four Gigabit Ethernet line
modules to comply with radiated emissions requirements.
Catalyst 8540 CSR Route Processor and Switch Module
Redundancy
The Catalyst 8540 CSR supports the use of redundant route processors and switch modules. The second
route processor would be installed in slot 8, and an additional switch module would be installed in
slot 6.
Route Processor
There are some precautions that need to be taken before removing a route processor module from a
chassis that is powered-up. If a route processor module that is currently running IOS is removed from
the chassis in a skewed manner such that the left side of the processor comes out before the right side
does, the traffic flowing through the device may stop flowing.
To avoid this, make sure the route processor module that is being removed is currently at the ROM
monitor prompt; it is then safe to remove it from the chassis. One way to get the system into ROM
monitor from IOS is to issue a reload command. This will work if the system is not configured to
auto-boot. If the system is configured to auto-boot, it starts booting IOS again.
