The document discusses Huawei's naming conventions for parts and components. It provides details on: - The 12-character naming structure which includes information on product series, component type, version, and specific part. - Descriptions of the last 6 characters which provide additional details on the part such as interface type, capacity, and attributes. - Explanations of the naming conventions for different part types including cards, MPUs, LPUs, flexible service units, value-added cards, and more.

1. Naming Conventions of Huawei Parts
The nameing Conventions of Huawei switches Parts
A card name contains 12 characters, which are divided into four segments, as
shown in Figure 1.
The Huawei S9700 card for exemple:
Figure 1 Card naming conventions
E H 1 D 2 S R U D C 0 0
a (the first three characters): represents the
product series. EH1 represents the S9700
series.
b (the fourth character): represents the
component type. The letter D represents a card.
c (the fifth character): represents the card
version, depending on the V version of the
product. For example, if a card is available in
V200R001C00 and later versions, c is 2.
d (the last six characters): represents the card
type and attributes. See Description of the Last
Six Characters in a Card Name for the meaning
of each character.

MPU
Figure 2 and Table 1 explain the last six characters in an MPU name.

Table 1 Description of the last six characters in an MPU name
ID Description
d1 MPU type:
• MCU: Main Control Unit of the
S9703
• SRU: Switching and Routing Unit
of the S9706 and S9712
d2 • For MCUs, this character is
assigned in alphabetical order (A,
B, C, and so on) to identify MCU
types.
• For SRUs, this character
represents the switching capacity
(A: 512 Gbit/s; B: 1 Tbit/s; C: 960
Gbit/s; D: 1.92 Tbit/s).
d3 Extended attribute. The letter C means
that the MPU has a clock daughter card.
This character is 0 by default.

3. d4 • A number that identifies the MPU
type. The number is assigned to
different types of MPUs in
ascending order from 00 to
99.entries.
Single-interface-type LPU
All the interfaces on such an LPU are the same type. For example, an EH1D2X12SSA0
card provides only 10GE BASE-SFP+ optical interfaces.
Figure 3 and Table 2 explain the last six characters in such an LPU's name.

ID Description
d1 Interface speed:
• F: 100M interface
• G: GE interface
• X: 10GE interface
• L: 40GE interface
• C: 100GE interface

4. d2 Number of interfaces on the LPU. The
value ranges from 00 to 99.
d3 Interface type:
• T: electrical interface
• S: SFP/SFP+ optical interface
• X: XFP optical interface
• Q: QSFP+ optical interface
d4 Card series:
• S: standard series. This series
does not support MPLS or
extension of table entries.
• F: common series. This series
supports MPLS but does not
support extension of table
entries.
• E: enhanced series. This series
supports MPLS and extension of
routing, ACL, and MAC address
entries.
• B: large buffer series. This series
has a large buffer and supports
MPLS and extension of routing,
ACL, and MAC address entries.
d5 Sizes of the MAC address table and FIB:
• A: MAC entries ≤ 32K; FIB
entries ≤ 32K
• C: MAC entries ≤ 128K; FIB
entries ≤ 128K
• D: MAC entries ≤ 512K; FIB
entries ≤ 512K
D6 A number that identifies the LPU type.
The number is assigned to different LPU
types in ascending order from 0 to 9.

5. Multi-interface-type LPU
Such an LPU has interfaces of two or more types. For example, an EH1D2T24XEA0 card
provides 10GE BASE-XFP interfaces and 10M/100M/1000M BASE-T interfaces. The
interface type with the largest number of interfaces is the major interface type, and the
other interfaces are minor interfaces.
Figure 4 and Table 3 explain the last six characters in such an LPU's name.

• Q: QSFP+ optical interface
d2 Number of major interfaces. The value
ranges from 00 to 99.
d3 Minor interface type:

• C: combo interface
• S: SFP/SFP+ optical interface
• X: XFP optical interface
