3.4 Card
3.4.1 What Does it Mean When an Indicator Is Yellow on a Card of a CE12800 Series Switch?
Table 3-18 describes the yellow indicators on various cards of a CE12800 series switch.
Card Name | Indicator | Color | Description |
|---|---|---|---|
MPU | RUN/ALM: running status indicator | Yellow | Steady on: The card is in power-off state. (For example, the card has been forcibly powered off using the power off command or is about to start.) |
SFU | |||
CMU | |||
LPU | RUN/ALM: running status indicator | Yellow |
|
Service port indicator | Yellow | Blinking: The port is transmitting or receiving data. |
3.4.2 Are Cards of the CE12800 Series Switches Hot Swappable?
All the cards of the CE12800 series switches are hot swappable.
- Main Processing Units (MPUs) and Centralized Monitoring Units (CMUs) support 1:1 hot standby.
- Switch Fabric Units (SFUs) support N+M hot standby. To remove an SFU, hold down the OFL button (at the bottom of the enlarged image) for at least 6s until the OFL indicator turns red (at the top of the enlarged image). Then remove the SFU from the chassis. Packets may be lost if you remove the SFU before the OFL indicator turns red.
3.4.3 What CMU Models Are Applicable to the CE12800 Series Switches?
The CE12804S/CE12808S/CE12804E/CE12808E/CE12816E chassis do not have independent CMUs, and their monitoring modules are integrated on the MPUs.
CMUs of the CE12804/CE12808/CE12812/CE12816 chassis include CE-CMUA and CE-CMUB. They differ in the following ways:
- They monitor and manage different quantities of power modules and fan modules.
- They are applicable to different chassis models and installed in CMU slots with different slot IDs.
Table 3-19 describes differences between the CE-CMUA and CE-CMUB
CMU Model | Maximum Number of Power Modules Monitored and Managed | Maximum Number of Fan Modules Monitored and Managed | Applicable Chassis Model and Slot ID |
|---|---|---|---|
CE-CMUA | 12 | 17 |
|
CE-CMUB | 20 | 23 | Slot 19 and slot 20 of a CE12816 chassis |
3.4.4 What Are Functions of the Ports on a CE-CMU?
Figure 3-36 shows the ports on a CE-CMU.
ETH port
It is a management port and supports rates of 10 Mbit/s, 100 Mbit/s, and 1000 Mbit/s. This port is reserved for future use.
RS485 port
Ports RS485 0 and RS485 1 are reserved for future function extension.
I/O port
Ports ALM IN and ALM OUT are reserved for future function extension.
3.4.5 Do Ports on a CE-L24XS-EC Card Support GE Optical Modules?
Yes, ports on a CE-L24XS-EC port card support GE optical modules. A CE-L24XS-EC card provides packet processing and traffic management on twenty-four 10GE optical ports.
- When the 10GE ports work in 10GE mode, they support SFP+ 10GBASE-SR/LR/ER/ZR/LRM/USR optical modules, and can work with 10GE Twinax high-speed cables or AOC cables.
- When the 10GE ports work in GE mode, they support SFP 1000BASE-X optical modules and 1000BASE-T copper modules. When using a 1000BASE-T copper module, a port supports 10M/100M/1000M auto-sensing.
3.4.6 What Are Differences Between CE-L24XS-ED and CE-L48XS-EC Cards?
A CE-L24XS-ED card has 24 10GE optical interfaces that share one chip. A CE-L48XS-EC card has 48 10GE optical interfaces that share two chips.
The ED and EC series interfaces cards support different numbers of FIB entries and ACLs, but they have the same MAC address table size.
3.4.7 How Much Is the Power Consumption of a CE-L36LQ-EG Card?
The typical power consumption of a CE-L36LQ-EG card is 605 W, and its maximum power consumption is 986 W.
You can obtain hardware specifications of the CE series switches using the Hardware Query Tool.
3.4.8 How Do I Know Version Support for Various Cards of the CE12800?
You can use the Hardware Query Tool to quickly find the version support for a card of the CE12800 or refer to the "Version Mapping" section of the specific card model under "Cards" in the CloudEngine 12800 Series Switches Hardware Description.
